Noise

The noise test consists of pictures of our studio shot taken at increasing ISO levels to show the effect on the image. The pictures were taken after resetting the cameras to their factory default settings. The cameras were then set to record with the highest quality option with manual WB.

Noise on both cameras is well-contained at ISO 50 and 100. However, at ISO 200 the images begin to lose a noticeable amount of detail and discoloration appears in shadow areas. At ISO 400, there is a large loss of detail and the images become very noisy. The Z3 appears to have a higher default contrast than the Z2.

    Stephen, thanks for the information (and the review!). I'm looking at using either the Z2 or the Z3 for astrophotography where I would need detail derived from dark areas. I like the antishake and separate viewfinder that the Z3 offers, but I think from your comments the picture quality of the Z2 would be better.

    Thanks again!

    There are certainly ways to deal with some of the Z3's shortcomings by doing post-work. However, There isn't a way to deal with the loss of detail in shadow areas.

    The real question is what issues will a new firmware address? It will be interesting to see what Konica Minolta will do.

    Until new firmware is released, is it possible to deal with Z3's flaws (e.g. under-exposure, darker images, colour reproduction) using standard image processing software?

    Kelh,

    Both cameras have an accessory shoe that fits Konica Minolta flash units: 2500(D), 3600HS(D), and 5600HS(D). However, these flash units are sold separately. I hope this answers your comment ;-)

    One of the things I never find in these reviews is wether the cameras include a flash stand. Sometimes the flashes that come with digicams are not good enough and night pictures look dark.

    Is it worth the price difference?
    Here in The Netherlands the difference is about €140,=.

    I think it is very much

    what the reviewers call jpeg compression artefacts may be just normal noise... I don't know...
    Depends on the reviewers...

    All cameras have some sort of horizontal lines...
    I don't see when it will be a problem.

    I think 3 mb for 4 Mpixel pictures show that the compression isn't very effective.

    It seems that Z3's flaws can be dealt with with firmware updates.

    Perhapos that is why the current new firmware 1.01e is not official yet, even though it solved many problems.

    In my mind these cams are uncomparable as one has image stabilisation and thoe other hasn't.
    It has to be compared with the panasonic or the canon.

    I had a Z2 for a brief period of time (I had to return it when my PSU killed my motherboard) and it was an awesome camera.

    The Z3 looks even better. I would recommend that anyone looking for a high-zoom camera check these out.
