jmahto Posted January 3, 2018 Share #21  Posted January 3, 2018 (edited) Advertisement (gone after registration) CL, CV 15/4.5 v2, f/4.5, 100 iso, focus on the tree at the top left corner.  C1010544_lisi_web.jpg  C1010544_lisi_crop.jpg Good results. Further click on removing CA (in LR) will make it even sharper (leaves will be well defined).  Now CL is becoming quite tempting.  But then again, on M240/M10, that will be a 12mp crop (with optional drama of full 15mm FOV in case you feel like using it). Decisions decisions... Edited January 3, 2018 by jmahto Link to post Share on other sites More sharing options...
Advertisement Posted January 3, 2018 Posted January 3, 2018 Hi jmahto, Take a look here CV 15/4.5 v2 on T/TL/TL2/CL. I'm sure you'll find what you were looking for!
lct Posted January 3, 2018 Author Share #22  Posted January 3, 2018 Well i would not compare APS to FF personally. SEM 21/3.4 asph, Elmarit 21/2.8 asph and even CV 21/4 are hard to beat on FF bodies and for sharper results i would use the CV 15/4.5 v2 at f/5.6 preferably. Same for the CV 21/4 which is a bit soft at full aperture as well. BTW the CV 15/4.5 v2 has no CA at all at f/4.5 in my view (see full size below) but it is a bit soft a f/4.5 and there were wind gusts when i shot this pic. Also the lens is hardly better than other M wides as far as field curvature is concerned so i would not rely on f/4.5 to get sharp landscapes with it actually. YMMV. https://photos.smugmug.com/photos/i-LJwc3HT/0/7e592ba3/O/i-LJwc3HT.jpg (20 MB file) Link to post Share on other sites More sharing options...

Very slight but will clean up nicely. I will try it tonight and see what I get.  Very nice result btw. Perfectly useable. I use this lens on my Nex-6 to get star trails etc. as well. Wide enough to give me good coverage. https://flic.kr/p/BwgtHs  and timelapse from the same sequence. Very useful lens for me while hiking.

There is indeed CA but it is very little (notice red fringes between leaves in the left pic). The following compares are at 200% zoom. I will consider the result pretty good. Welcome, dear visitor!

lct Posted January 5, 2018 Author Share #25  Posted January 5, 2018 Just trying to hand code the CV 15/4.5 v2 as a WATE on the CL. To no avail so far. The camera sees it as an "Unknown Lens". I use the 010000 code (pic) and same "Zebra" permanent marker as for my other ZM and CV lenses though. Am i doing something wrong?  Welcome, dear visitor!

Exodies Posted January 5, 2018 Share #26 Â Posted January 5, 2018 The frame line selector has to match that of the coded lens, I think. Link to post Share on other sites More sharing options...
jdlaing Posted January 5, 2018 Share #27 Â Posted January 5, 2018 Advertisement (gone after registration) The frame line selector has to match that of the coded lens, I think. Not in the case of the WATE. The mount, however, has to activate the proper frameline trigger to make the selection register with the camera. I think it trips the 28 or 35.

Â I thought of that as well but the CV 15/4.5 v2 brings up the same 28/90 framelines as those of the WATE on M cameras. Curious that the CV 21/4 is so easy to hand code by comparison.

jmahto Posted January 6, 2018 Share #29  Posted January 6, 2018 (edited) On M240 I use 000001 (21mm 2.8) but still have to use flat field if there is lots of sky. Welcome, dear visitor!

lct Posted January 6, 2018 Author Share #30  Posted January 6, 2018 On M240 I use 000001 (21mm 2.8) [...] Photo Jan 05, 4 53 37 PM_small.jpg  Works fine with my CV 21/4 on the CL but not with the CV 15/4.5 v2.

lct Posted January 6, 2018 Author Share #31 Â Posted January 6, 2018 All the more curious that the CV 15/4.5 v2 is recognized as a "4/16mm" lens by my M240 in auto lens detection mode and w/o any coding. Link to post Share on other sites More sharing options...

Never noticed that, and I can't verify since I have already coded. Are you sure it is not due to some bug (residual code from earlier mounted lens or something like that)? Or dirt on the sensor? The coding area on this lens is fully clean without any marking, that's why I am suspecting something funky in the camera side.

lct Posted January 6, 2018 Author Share #33  Posted January 6, 2018 The bug was in my brain sorry... Forgotten to remove hand coding from the lens... No wonder why the lens was recognized then... Now this proves that the lens is properly coded at least. Yet it is recognized only by the M240 i don't understand why... Oh well i will assign it a profile in the CL for now. Link to post Share on other sites More sharing options...
