Live View and the Optical Viewfinder

Sony Live View impressed us at PMA, and now that we've spent more time with a production A350 we are even more impressed with the Sony version. Sony Live View is definitely unique compared to others, and their description as Quick AF Live View is justified.

Everyone else now uses the imaging sensor to provide Live View, and while that method works and is fairly cheap to implement, it does have serious limitations. First, it eats precious power, as the mirror has to be flipped up and held out of the image path during Live View. Second, the camera must flip down the mirror for focus and metering, which slows down shooting and momentarily turns off Live View. This makes Live View more a check-box feature on today's digital SLRs than something truly like the Live View seen on Point-and-Shoot cameras. Some variations of this exist, such as the Canon Live View system with contrast-detection focusing that has been announced for the Canon XSi, but all the Live View systems have been slower and less capable than optical AF.


In the A300 and A350, Sony introduces a totally different Live View System, based on an additional live view sensor and a tilting pentamirror. In the Sony Quick AF Live View, the pentamirror tilts and the optical viewfinder closes during live view. It can also run continuously without overheating the sensor, which is an early reported problem with the Canon system.


One huge improvement from the prototypes we saw at PMA is the top mounted switch for Live View or the Optical Viewfinder. It is a mechanical switch that works with or without camera power, and it is exceptionally easy to slide without the excessive resistance we saw on the PMA cameras. When the switch is in Live View, the viewfinder blind closes so there is no mistaking the camera mode.

In our shooting with a production A350, the Quick AF Live View seemed just as fast as the optical viewfinder. Sony specifies a slight speed penalty with Live View, however, with continuous shooting of 2FPS in Live View and 2.5FPS with the Optical Viewfinder. If you look closely at the specs on page two you will see this is slower than the 10.2MP models (A200 and A300) which manage 3FPS with less info to write with the lower-resolution sensor.

Those who are used to the Live View capabilities of their point-and-shoot digitals will love the new Sony A350 and A300. They will seem very familiar and Live View is exceptionally easy to select and use. The bad news is that the 2.7" Live View LCD only shows 90% of the image you will capture. That won't matter for the snapshots LV will mainly be used for, but it is an obvious problem if you are using Live View for high or low-angle Macro shots with the tilting Live View Screen. When you process or review the captured images, there is a lot more around the image than you framed on the Live View screen. Keep that in mind during critical shooting and it will be less of a problem.

Optical Viewfinder

It's a good thing the Live view is useful and fast because the optical viewfinder is absolutely horrible - both dim and tiny with a pronounced "looking down a tunnel" effect. You can see why this is the case with a close look at the viewfinder specs on page two. The top A700 has a good viewfinder with a .90x magnification, and it uses a true pentaprism for a bright clear image.

The 2006 A100 had a decent .83X pentamirror viewfinder that was both larger and brighter than normally seen on cropped sensor DSLR cameras. That viewfinder appears to be carried over intact to the new A200. Then there is the new A350/A300 with a .74X optical viewfinder. The view is reasonably bright - for a light at the end of a tunnel - but the tunnel is so long you are left with the impression that the viewfinder is dim. The screen itself appears tiny and the usefulness of the optical viewfinder is seriously reduced in the A350 and its sister A300.

If you will mainly shoot with the optical viewfinder and don't really care about the tiltable LCD and Live View, then go with the A200 as the viewfinder is much better. The fly in the ointment comes if you want the 14.2MP sensor because the other options are 10MP - and that gives the A350 about 40% higher resolution than the other entry-level Sony cameras.

It's a good thing the A350 has good full-time Live View because we would flunk the camera if we had just the optical viewfinder to depend on. Even the tunnel-like Olympus E-510/410 viewfinders are better than the new A350 - and they are hampered by the smaller sensor with the 2X multiplier. There are ways to get around most viewfinder issues as Olympus showed us with the superb viewfinder in the new E-3, where the small sensor is assisted with a high pentaprism with a 1.15X magnification. The A350 optical viewfinder is usable, but in general it is pretty awful. Sony really needs to improve this viewfinder because it will matter to most users who don't mainly use Live View, and many will be buying this camera for the 14.2MP sensor and not just the Live View.

    When it comes to measurebaters, I know what you're talking about. However, it's not the case here. You are not saying that comparing images taken with different aperture values and exposure times aren't visible in real life, are you?

    As said before, what people are demading aren't quite huge here. It's as simple as taking pictures in possible same conditions. People aren't demanding to remove all variances. People are demanding the reviwer to follow just basic rules. Really, think about it. What kind of a reviwer tests cameras using AUTO mode unless it's done so for the sake of it? Even worse, what kind of a reviewer compares resolution of the camera when the aperture value is all different on a such a shallow /f lens?

    BTW, where did that "If its not Canon/Nikon, its not a camera" come from? Last time I checked, nobody here put down A350 or K20 because they aren't Nikon/Canon cameras. In fact, people put down the review as it was done such, if not less, an amateur level.

    When people are pointing the obvious, don't water it down by saying that they're just being measurebators and Nikon/Canon fanbois. It only helps the ego of the person not the review; What people here care about is the quality of the review, not the ego of the "PRO" photographer reviewer.

    If you take a look, I was one of the first few people who commented on the different apertures throwing the test, which was brought up days before 50 other comments jumped on the bandwagon, and was fixed swiftly. Wesley also acknowledged all the CONSTRUCTIVE criticism civilly and took it onboard to improve his review, it wasn't until people starting on about stuff like varying ISO standards and default settings between camera brands that he became mildly irate. You can't seriously say that level of bitching isn't measurebation for this sort of review.

    Crap like that never ends. If you judge on jpeg quality, the settings between cameras becomes a variable. If you judge on RAW, the converter used becomes a variable, and the level of NR that in some cameras can't be disabled.

    He made some mistakes in his first review, and fixed them. Very few of the later comments were valid, but people keep harping on.

    Last time I checked, I said OTHER REVIEW SITES are often biased towards Canon/Nikon.

    The test methods the reviewer used would be the call for 'measurebators' as it measurs the difference between cameras; You can expect someone to not measure when the review itself is based on measurement. How can you do a camera review without being a measurebator in the first place? www.luminous-landscape.com would be the answer. If he's a "PRO" photographer who doesn't know much about measuring cameras as witnessed, he should just write up reviews Luminous-landspace way. That'd be the perfect solution.

    You see, the problem we have here is how he's setup a testing system that's got too many variables. People didn't demand him to to varible free, people demanded him to be get rid of ridicoulous varibles. He did manage to fix some of the problems yet some remains. I suggested that he mention and explain it if he's doing it for some purposes. As you probably know why, a reviwer shouldn't just throw out images and compare them without letting the people know about crucial settings being different.

    About the Canon/Nikon comment.
    I was mostly refering to the reviwer's reply although it was directed to someone else:

    "You could just stop the pain, stop reading, and move on to comfortable sites where Canon and Nikon always top the performance charts and always win every award"

    Now, isn't it just silly when the reviwer gets all personal saying stuffs like that when he's the one who created this chaos?

    Now would probably be a good time to stop writing prosumer DSLR articles. This whole thing is littered with inaccuracies and just plain incoherent information. Reading this really reminds me of when I interview people for jobs they are not qualified for, and they just break down and start tossing out buzzwords. I got no problem with AT publishing some SLR articles, but they at least have to make sense. Heck, you did not even compare the Sony against the compatable Nikon and Canon models. Why the hell would you use a 5D? The 5D is in a completely different class, and the Pentax has such a small share of the market. This is basically a slap in the face to anyone who is a camera enthusiast.
  • Wesley Fink - Friday, April 4, 2008 - link

    How rude of me to compare ISO noise of a 12.2 megapixel “low-end Pro” full-frame 5D to a pedestrian 14.2 megapixel APS-C Sony and a “tiny market share” 14.6 megapixel APS-C Pentax. I suspect a comparison to an APS-C Nikon D300, which at $1799 is very close in actual price today to a 5D, would probably be OK. Or can I only compare the Sony A350 to current 10-meapixel APS-C Canon and Nikon models priced below $899?

    You really don’t have to put up with this sacrilege. You could just stop the pain, stop reading, and move on to comfortable sites where Canon and Nikon always top the performance charts and always win every award.

    Of course I knew what you were talking about when you mentioned ISO variance among cameras at the same ISO setting. I am always willing to listen to constructive criticism, but I have little patience with comments that are self-serving grandiosity. I have made a living as a PRO photographer - have you?

    You should also mention that almost every NEW camera that has been tested for ISO speed variation is today largely correct in the reported ISO. I am aware of the issue but its importance today is low and not that signigficant to our intended audience. The biggest offender was Canon, and their newer cameras are now testing correct as well. I doubt, however, that your real goal was to share information. It sounds from your tone that your goal was to belittle rather than educate or provide constructive criticism..

    -------------------------------------------------------------------

    As another person has already pointed out, your being professional photographer doesn't make you a decent reviewer. I do have friends who are professional landscape/wedding/sports photographers but they don't know much about cameras than I do.
    They know it,I know it and we know our boundries: They don't write thoughtless reviews on major review sites and I don't claim my pictures are decent because I know well about cameras in terms of mechanics. It's the same case when it comes to many subjects. A good racer wouldn't argue with mechaics by saying 'I have made a living as a PRO racer - have you?' A good progammer wouldn't try to argue with hardware geeks by saying 'I have made a living as a PRO programmer - have you?'
    As you can see, I hope, it's just silly to come out with that logic even if we're all in elementry school.

    You claim that you knew what I was talking about when I mentioned ISO level being different on certain cameras. Maybe you did and I do hope you did. However, when I mentioned it, you came with some weird answers; you said it'd be fine as you have updated the firmware to the latest version. If you knew it, why did you have to come out with such a nonsense answer?

    -------------------------------------------------------------------

    I don't know everything, but you haven't mentioned one thing that I don't understand, so please get off your soap box. We have stated many times that we have no desire to mirror dpreview. They are a terrific site for photo information and in-depth reviews. I have read and enjoyed them for years, but they are not everyone's cup of tea. Most of our readers are intimidated with the info at the dedicated old school photo sites and they have asked us to provide reliable information at a lower level. That is our intention.

    --------------------------------------------------------------------
    As I've already said, I don't expect you to know everything. I just want you to know very basic stuffs. No, I don't want you write Dpreview levels of reviews. I just want you to write reviews that are not thoughtless. I don't know why you're making it sound that I expected too much of you. As I said, I just expect the camera review at least half of the level of another Anandtech articles done by other guys. You see, you remind me of this kid who yelled out loud that he doesn't want to be Einstien when I only told him that 1+1 isn't 11.
    BTW, how can you possibly claim "provide reliable information" when you keep used thoughless testing methods? Using different aperture values on different cameras then talking about resolution? Uploading ISO 800 images claming it's the ISO 1600 imgages? Using Bright mode and high contrat/saturation settings on K20D when other cameras were set at standard mode?

    --------------------------------------------------------------------

    I also briefly discussed the impact of noise reduction in the review and I am keenly aware of the ongoing discussion about the impact of noise reduction schemes on image detail. I also am aware the K10D is best RAW and the noise reduction algorithm is poor, but that is from my experience with the camera. I might add that the K20D behaves differently - from experience - but you don't know that yet because while I have done a first hands-on look at the K20D, the major photo sites haven't posted any real reviews of the K20D yet.

    --------------------------------------------------------------------
    What makes you think I woudn't know? Because "major photo sites haven't posted any real reviews?" How Silly that is.

    First of all, There're two ways of NR fuctioning on K20(Might have been fixed as users demanded firmware solution to get by it): When the shutter speed is longer than 0.3 sec, or ISO is higher than 800. This means when the shutter speed is lower than 0.3 sec or if ISO is lower than 800, the NR would be off. Now this is crucial because there have been reviews where the thoughtless reviewers thought they did a fair test not realizing this, thus coming out with a result that made K10D to look like it's got less noise. However, K20D provides images with more noise with greater details.

    In addition, K20D has somewhat hidden fucntions such as 'fine sharpness' mode which provides better sharpness/detail solutions yet it's put deep in the menu as it increases the noise.

    Oh and K20D uses Samsung sensor that has a utilizes wider photons thus providing less noise without the much help from a software noise algorithms.

    BTW, how can you say that K10D has poor noise algorithms when you said this about A 350? "The good news about the sensor is that output is very clean and noise remains low up to ISO 1600"
    If A350 high ISO images look good to you, K10D should be the same if not better.
    --------------------------------------------------------------------

    Yes, we made errors in this first real DSLR review, but we have worked diligently to correct them. I have just posted the crops and full images for the reshoot with the Sony A350, so all images are now consistent in shooting conditions and they can be fairly compared. I think you will find what I concluded in my initial review can now be more clearly seen in the crops and full images.

    --------------------------------------------------------------------
    True that there were many errors yet you made a same error. Check out the exposure time of K20D and 5D.
    --------------------------------------------------------------------

    We are obviously too basic for your tastes and I wouldn't want your head to hurt with the drivel you see here. By all means continue to get the information you need from the current established photo sites. We are aiming to provide reliable information to a wider cross-section of users and we will not likely satisfy the level of detail you seek.
    -------------------------------------------------------------------
    Again, I do want GOOD basic reviews. I do not expect you to write in-depth reviews. The problem is that your reviews are not even fair even in the basic level. As pointed out by many others, you reviews are not only less than basic but also very misleading when you test iamges using all different aperture values with mixed in-camera image settings. I and some others who have basic knowledge could point out the terrible mistakes you committed but those "wider cross-section of users" woudn't be able to do so. That's what concerns me.

    Don't take it personal. I never said you're stupid. It's your review that is stupid and as you're not a stupid person, the review written by you shouldn't be stupid. Stop making "honest mistakes" and work on it so it can be "reliable." Those stupid "honest mistakes shoud stop here. After all, this is not your blog, it's Anandtech.
  • Wesley Fink - Thursday, April 3, 2008 - link

    I did not "commit the same error" in the reshoot. I used aperture priority and manual focus as I stated in the article. I did not intend to use, nor did I use the same manual exposure settings on the various cameras.
  • Deadtrees - Friday, April 4, 2008 - link

    If that's the case, as I said, you should've stated how using AV mode on ISO resulted different exposures and the possbile reason why it was so. Not doing so just falls into the same category of mistakes you've made. Think about it. 1 sec. vs 1.5 sec of exposure difference is quite huge; it is something readers should know and reviewers ought to inform. Without knowing it, the point of comparing ISO noise level tests loses much of its meaning.

    In addition, you really need to explain why you used bright mode along with high contrast/shrpenss settings on K20D when all the cameras had their default settings. What's your "intension"? Was it just one of those your "honest mistakes"?

    Again, if you intend to use some weird and all mixed methods testing cameras, let the readers know about it. I really don't think you're on the payroll of some companies but the "honest mistakes" you've made were testing methods done by reviwers who were on it.

    You see, what you've done is like comparing CPUs with same GPU so that reders would think it's the set setup yet one GPU is underclocked. Given that, of course, one CPU will look worse than the other as the tests were not fair. And you know what you've done is even worse than that scenario. Stop coming out with excuses like "honest mistakes" and "intension" that doesn't make sense.
  • Wesley Fink - Friday, April 4, 2008 - link

    Bright mode appears to be the default mode on the K20D. I did not "tweak" or adjust saturation or contrast on the K20D. In Bright mode Contrast is +1 and Sharpness is +1. The choices are Bright, Natural (with -1 Sharpness), Portrait (all at default but not the default mode), Landscape, Vibrant (another all at default mode) and B&W. None of the custom modes really do very much as the greatest variation is +/-1 in the modes with a potential adjustment range of each value of +/-4. The camera was reset prior to shooting the images to set default values.

    I have checked the "hidden" settings in the Fn 'Custom Image' menu and see nothing out of the ordinary, but I do see the EXIF details you mention. I will check with Pentax to get a better understanding of how the 20D controls these parameters.
