  • Both the flare problems seem to be solved with the new setup, this is a very nice improvement. Thanks everyone for commenting :-) I'm now starting to experiment with HDR to handle the most...
  • After some experimenting I'm now using my Sigma 2.8/150 macro instead of the Micro-Nikkor. As a result, the Liveview exposure problem is gone, and during the experimenting I discovered that one of...
  • I don't have any reference, just from what I remember from long ago when I was more involved in macro stuff and needed critical sharpness. I'm using 'real macro' for lenses designed for 1:1 or even...
  • From what I know most of these 50-60mm macro lenses are optimised for about 1:10, just like most enlarger lenses. They are still pretty good near infinity or 1:1 (stopped down a few stops),...
  • Replied in But how small?
    agree, these 28mm lenses look better in the corners than many DSLR WA lenses ... (except maybe some of the most expensive ones).
  • I have two flare issues: one is a slight increase in brightness near the sides, which points to a problem similar to what you mentioned. This occurs in some of the slides and is only visible in...
  • Do you consider the RX100 too big? In a few months we will probably see how small Canon can build such a camera with relatively big sensor. They have lots of expertise in this area with the S...
  • Please give one example of a camera/lens combo that beats the GR in image quality at 28mm or 21mm effective for similar or lower price and size/weight. I don't think there is any ... Like others...
  • Replied in Conclusions...
    thanks, you answered my question :)  So apparently the GR indeed has a better lens than the DP1 - when used near infinity and near wide open. Those parameters are important for me as I mostly do...
  • Thanks for the feedback and enjoy your 6D :-) I will definitely consider HDEW if the 6D prices in my area stay at the current high level.
  • yes, I have read that page some time ago; will check again :-) Yes, it might be related to the diffusion enlarger head. I'm using the 6x6 setting on my M605 for 35mm slides. When I use the 35mm...
  • thanks for the feedback :-) I have been using a similar procedure lately. Unfortunately, the slides are not allways 'correctly exposed' and even if they were, I sometimes have to make minor...
  • Replied in Conclusions...
    please don't use selective quoting then, because your quote is taking my remark out of context (at least in my view).
  • Replied in Conclusions...
    I'm not comparing apples and oranges (I'm talking about three 28mm effective f/2.8 lenses) and I'm sure that at least some of the comments I read were not doing that either, they were from people...
  • Replied in Conclusions...
    my impression was that the GR is clearly better in the corners at long distance (near infinity), but that at average distance e.g. for street photography there is no clear difference, maybe only a...
  • CMOS requires a lot more effort to get a decent picture compared to CCD. This effort can be either lots of extra on-chip circuitry and/or additional in-camera processing. Canon showed with the 5D...
  • Replied in GR hood
    There is an optional rectangular hood for the GR. Big compared to the camera, but probably very effective. Looks fine to me, for situations where one could worry about lens flare etc.
  • IMHO that is the wrong choice for your applications when you use an APS-C body. The 24-105 is designed for FF, on crop the 15-85 will give you FAR more reach (on the wide side, slightly less on the...
  • My guess is that the optically corrected lens would always be more expensive because it requires more elements. Software correction is a one-time expense (give that there already is a special image...
  • The corrections that take place in the corners/borders with several recent compacts with bright WA lens are more destructive than small level, perspective or cropping corrections. If you check what...
