  • Very likely.  Close shots require very good alignment to the target. No, of course not.  Lenses are designed to have flat fields after all... That said, field curvature can be worse at close focus ...
  • That’s not quite what is happening.  Panasonic and Olympus cameras both have UV filters in them the difference being Panasonic cuts at a longer wavelength than Olympus.  As you mention this means ...
  • If you have issues when using a 420nm filter then it is going to have issues on a Panasonic body as well.  So it isn’t a Olympus vs Panasonic issue as the OP is asking about. I tested the 8–18 on ...
  • Heavier, larger, more expensive and: Or lighter, smaller, less expensive and: The usual trades in size, weight and cost vs. image quality. The 40/2 looks so far like a delightful small lens that ...
  • The Amazon case is interesting in particular as it is a failure on their part to control their inventory and supply chains sufficiently to reject counterfeit items.  Worse, the way Amazon does ...
  • So actually the issue is Sony never does anything about the "bright" banding (or I think more commonly called "striping") that can rarely occur on PDAF sensors. So on some Sony cameras you'll very ...
  • How are you being a "good guy" exactly? I never order from anywhere without checking their policies which Nikon very clearly states: Nikon Store Return Policy Subject to the exceptions, time ...
  • Replied in Disagree
    Nikon products cost exactly the same amount in a bricks and mortar store as they do at an online retailer (and that includes nikonusa.com that the OP is complaining about).  That's the whole deal ...
  • If you follow through the thread and all of its branches it appears the camera is making some sort of estimate from the scene as to whether PDAF mask reflections are likely to cause what I'll call ...
  • It is apparently not unusual to not see banding as so far it appears to be the result of a somewhat ham-fisted attempt by camera processing to eliminate the potential for a different kind of ...
  • You know, my experience with xRite is quite old - probably at least five years at this point - so it is quite possible it is either by default or by some settable option now actually computing its ...
  • Yes!  Unfortunately xRite just copies the WB computation matrices from the LR profiles and never computes it's own new ones so it is dependent on LR/ACR getting it correct in the first place.  In ...
  • As folks have already pointed out there was a change in how camera settings were imported into LR awhile back.  Another very important change for the Z7 specifically was that for a good long while ...
  • Yep, that's right.  So if you want it to refocus each time you can as long as you have half press focus enabled.  If you use back button focus instead then it won't refocus.  Or of course if you ...
  • It’s up to you.  You can either lock focus at the start or have it refocus each shot.
  • In these situations I find it easiest to just set the camera on time lapse taking an image every five seconds or so. Then you can walk to your family calmly and even try a few different poses.  It ...
  • What it had was a service advisory for a tiny number of the very first units off of the production line which Nikon was servicing free of charge. And which Nikon proactively on their own went out ...
  • People who have followed their ever changing pages over the years where in the past they were more explicit about what they did and then took the time to verify what they are doing from their ...
  • DxO doesn't use a black frame for DR.  Their DR figure includes shot noise as well.  It is just with their lower SNR threshold for acceptability typically there is mostly read noise and little ...
  • Ah yes, I see that now.  Sorry I swept in too quickly!  Sounds like we are on the same page. Yes, agree.  Of course both DxO and Bill are doing this entirely for free so I'm prepared to cut both of ...
