And the face detect does seem to act as DPReview reported, sometimes I would get the closest eye and sometimes the farthest in focus. I haven’t seen any Leica claims outside of including “face recognition.” Link to post Share on other sites More sharing options...

hillavoider Posted February 23, 2021 Share #163 Posted February 23, 2021 (edited) So DPreview made that up? I’d put 100 dollars down on them being told it has eye auto focus at the launch just like all the sales people did at the Sydney launch and the Sydney store unfortunately they have covered their Lieing backsides very well, there is no mention of it online like you have pointed out Edited February 23, 2021 by hillavoider 1 Link to post Share on other sites More sharing options...

Slender Posted February 23, 2021 Share #174 Posted February 23, 2021 All I know is that I did some corporate portrait session for most of the day last Friday, and I decided to trust face/body detect mode and iAF or AF-S so the viewfinder stays sharp all the time. All worked fine with accurate focus, a single miss on 93 shots, certainly because I got distracted whilst adjusting something. I would be indeed cautious when using shallow DOF with low magnification focal length (lets say: you can missfocus from closest to furthest eye on a face when your subject is not facing you straight.... and not notice easily with a 35 f2 at a distance.... whereas if you are up close with a 90 you will see before pressing the shutter that the camera is not getting it right). I heard before that the Face detect mode of Leica does detect the eyes (its a facial feature after all) but does not highlight those individualy, and therefore can induce the "far eye in focus" quirk more easily without the user noticing. Sony A1 testers already complain it focuses on eyelashes most of the time. I also heard Canon R5 users complaining their cameras focus on the "deep inside of the eyes" 😜 on the contrary. I did not have any of those issues so far.... it's either OFF focus (completly, but thank god seldomly) or DEAD SPOT ON with my SL2 when it comes to face/eyes. Never trust your camera to do all the hardwork, but given the right settings and conditions, the SL2 AF is deadly accurate. I wish ((american)) war planes would use such a system 🤯🤠🤪 2 2 1 Link to post Share on other sites More sharing options...

Can you post any photos at F5.6-F11 at infinity focus? My M Summicron 28 is very good at close focus distance and wide open but infinity rendering is not to my liking. I'm seriously considering SL2-s + SL35 or SL28 lens in the future. How about distortion at infinity/landscape/architectural shots? Any impression yet? Maybe it is just me, but from Jono beach photo it seems all people in the left corner are somehow distorted... Jono at the beach seems to be using f/2.0 (and probably electronic shutter) but his picture overlooking a distant highway and farms was taken at f/6.3 and is really sharp. I noticed the leaning people at the left of one beach shot (but not at the right) and wondered if there was a contribution to this from the distortion correction that LightRoom applies when rendering the DNG with a small postprocessing correction. Leica left a little bit of barrel distortion in this lens, which pushes things in at the corners, and there are three sorts of things that can easily be done about it. A -- (the purist solution) just go with the pixels that you have got, don't correct anything, because that requires interpolation and possible loss of resolution. B -- (Adobe's default) reverse the barrel distorition by pulling the image out at all corners, but then trim what you have done down to the original pixel resolution (you only get what you paid for). C -- (The full Monty) keep all the stretched pixels, only trimming at the edges to make them straight and square. This gives 50.5 M pixels rather than the original 46.7, a nice benefit. I borrowed a few of Jono's DNGs and tried rendering them in Capture One, which lets you control this final step. In particular, I was looking for any loss of resolution from the interpolation. Didn't see any. The distortion correction makes things in the corner a little larger and rotates the overall image slightly. Here are two cropped examples, using method A (correction disabled) Welcome, dear visitor!

scott kirkpatrick Posted March 4, 2021 Share #180 Posted March 4, 2021 (edited) As the excitement today is all in the M lens threads where there is a new APO 35 Summicron to first leak via pictures and then compare. Steven in those threads has one of the new M 35 and his first impression is that the it puts the SL 35 (Peter Karbe's "best lens ever brought to market " as of a year ago) to shame. I'll leave that comparison for him to prove. I'm learning things about my new SL APO 28 Summicron. Such as how well does it do very close up, and how strong is the barrel distortion that is corrected in software. And does that actually matter, since it is the designer's choice to correct it that way. So I set up a test target to be shot at the closest distance for which I could get autofocus to succeed. This was 7.5 cm from the end of the lens hood, 10 cm away from the end of the lens otself. This is so close that even lighting is hard to achieve, so the test target is on my editing display: Welcome, dear visitor!
