arthury Posted February 7, 2014 Share #1 Â Posted February 7, 2014 Advertisement (gone after registration) I had a 90mm 'Cron APO some time ago but sold it away. It produced beautiful images on my M9 but focusing it correctly was a challenge and composing using the smallest frame-line was poison to my soul. Â Question: which frame-line is the 75mm 'Cron using when it is engaged into an M9 or M240? Link to post Share on other sites More sharing options...

MarkP Posted February 7, 2014 Share #2 Â Posted February 7, 2014 The frameline inside the 50mm frameline. Link to post Share on other sites More sharing options...
erl Posted February 8, 2014 Share #3 Â Posted February 8, 2014 75 cron is a fabulous lens but a challenge to focus. IMO, harder than a Noctilux. But don't let that put you off. Both are rewarding lenses. Just need practice, practice, ......... Same as using a RF. Link to post Share on other sites More sharing options...
hoppyman Posted February 8, 2014 Share #4  Posted February 8, 2014 Every time this topic comes up, I think "Am I the only one with this lens working perfectly? ":confused: Well I guess that most of my use would be at f/4 for portraits, not wide open but I LIKE the precision of the focus mechanism and much prefer it over the longer throw lenses for my style at least. I have very little experience with the Summilux though. f/2 Thoughtful in BW photo - Geoff Hopkinson photos at pbase.com ~f/2.8 here.

Flyfisherman Posted February 8, 2014 Share #5 Â Posted February 8, 2014 I recently gotten a 75 apo as well...I discovered that when I take close portraits under certain light conditions indoor, my subject gets a greenish forehead or chin. Wonder if anyone here hv similar experiences? Link to post Share on other sites More sharing options...
MarkP Posted February 8, 2014 Share #6 Â Posted February 8, 2014 Geoff, Â mine was bought new, was out of calibration on delivery, and was impossible to focus wide open. Â Perfect after a trip to Leica. I have no problems with the short throw focus No abnormal colour casts. Â Lovely lens. Link to post Share on other sites More sharing options...

Impossible to say anything definitive without your picture of course. Link to post Share on other sites More sharing options...
erl Posted February 8, 2014 Share #8 Â Posted February 8, 2014 Geoff, Mine is working perfectly, as is my Noctilux. The problem is the user, not the lens. Â I work frequently at speed and without pause or time to deliberate. That does pose a challenge for the short throw of the 75. OTOH the long throw of the Noctilux can be a boon by slowing one down to be more deliberate. It is mostly user error that we all fall foul of. Not the lens.

Peter H Posted February 9, 2014 Share #9 Â Posted February 9, 2014 I don't yet know whether it's love or infatuation, but I think my new 75 Summicron is simply wonderful. Â Time will tell since I've only had it for three days, but so far, it's my new sweetheart. Â Mind you, the rest of the harem are already getting restless!

mctuomey Posted February 20, 2014 Share #12  Posted February 20, 2014 Just received my 75 cron. Dragan-style test portrait of my son, wide open, M9:  my son by shadowcrusher, on Flickr  I like the short throw versus, say, the 75 lux or 90 elmarit-m.

erl Posted February 20, 2014 Share #13 Â Posted February 20, 2014 Congratulations on your acquisition Mike. It is a truly delightful lens and a most useful focal length, IMO. Â Beware of that short throw for focussing. If, like me, you indulge a lot of spontaneous shooting, that short throw can throw your focus off with the slightest nudge. I believe it is the hardest lens in the Leica range to maintain focus.

mirekti Posted February 21, 2014 Share #15 Â Posted February 21, 2014 I've been using this lens a lot, and reported a funny black mark on the helicoid ring which I learnt every 75mm Cron lens has. What I understood, in some cases it is visible, and in some it is hidden behind the mount part of the lens. Â Anyhow, I was offered by Leica to examine the lens, and not sure whether to send it or not as the lens is great as it is. The only reason that might make me change my mind, and send it for a check up, is exactly the above mentioned short throw. I do like it a lot, but I find the focusing ring too easy to turn. Do you believe Leica could make the focusing ring turns harder that it is at the moment? Â A bit ironic though, 135 APO has the longest throw of my lenses, and the focus ring is the stiffest. :-) Link to post Share on other sites More sharing options...
erl Posted February 21, 2014 Share #16 Â Posted February 21, 2014 Sending the lens back will not alter the 'short throw'. That is the design. Changing the lubricant to a thicker grease can tighten the focus feel, but in very cold weather can get too stiff, possibly. Link to post Share on other sites More sharing options...
Peter H Posted February 21, 2014 Share #17 Â Posted February 21, 2014 Everyone should have at least one "difficult to focus" lens in their collection. It makes you appreciate how easy the others are. Link to post Share on other sites More sharing options...
tobey bilek Posted February 21, 2014 Share #18 Â Posted February 21, 2014 In my opinion it is not the short throw, but something is different in the .68 digital finders. It is much easier on my .72 M6. Â I understand the 240 VF is improved , but still .68 . Don`t have one. Â The 75 is a great lens, but hard to focus even with perfect vision. I can miss focus on a subject at 300 feet at 5.6. Been using Leica since 1980 and never had focus issues. Link to post Share on other sites More sharing options...
mctuomey Posted February 21, 2014 Share #19  Posted February 21, 2014 Peter: good one probably should just stay with a 28mm zone focused at 5 feet, then just point and shoot  Tobey: well, for what it's worth, i have a M6 ttl and a couple digi M's. i don't find a difference in ease of focus with longer lenses between them. i do miss focus at times on all my bodies - my eyesight is not so good and i often shoot in poor light and dark venues. i haven't tried the M240. i understand it's better than its predecessors from comments on the web and reviews.

Wonder if anyone here hv similar experiences? Â Generally when I see that it is due to mixed lighting and often fluorescent light sources are involved. In that situation a white balance that gives proper skin tones will result in a green tint in the highlights. My solution is selective color balance using Lightroom 5.
