mdg1371 Posted March 23, 2015 Share #1 Posted March 23, 2015 Advertisement (gone after registration) Anyone using the limited edition collapsible Konica 50mm f2.4 on an M9 or M240? I've tried searching, and the scant few threads that are present are either pre-digital, or are M8 centric. I'm looking for as much detailed information as possible as to the qualities of the lens-- resolution, bokeh, mechanics, etc. Any feedback appreciated.

Advertisement Posted March 23, 2015 Posted March 23, 2015 Hi mdg1371, Take a look here Konica 50mm f2.4 on full frame bodies. I'm sure you'll find what you were looking for!
graphlex Posted March 23, 2015 Share #2 Posted March 23, 2015 I used to have one. Magnificent optics, somewhat sloshy mechanics. DAG told me that the looseness of the mount was due in part to Konica's grease, which included Teflon. I expect it would shine optically on the M240.

furcafe Posted March 24, 2015 Share #3 Posted March 24, 2015 (edited) I've had one for just over 6 years, using it to replace a 50/2.8 Elmar-M (modern version). It works fine on the M 240, just like it did on the M9, M8 & my film bodies. Not sure how to describe its qualities (including boke), but mine appears to live up to its excellent reputation. IIRC, Erwin Puts tested it as slightly better than the Elmar-M; I can't say that mine is noticeably better than the Elmar, but it's certainly comparable. As far as mechanics/build quality, it is made of a lighter alloy than the chrome Elmar-M I had so was noticeably less heavy, so probably more like a black Elmar-M (my Hexanon has the silver finish, but it's not chrome plate on brass like the Leica). The focus action is smooth &, as already mentioned, there have been no focus-related problems on my digital bodies (which is consistent w/my experience w/all of my LTM & M mount Konica glass). There is a tiny bit of play in the lens tube when the lens is extended, unlike my Elmar-M (more like a 1930s-40s Elmar), but it doesn't seem to have any optical effect. Don't have too many samples online, & none digital right now (a couple years behind on my flickr uploads), mainly because it's way too slow to be in my regular rotation. I had originally thought I was going to use it as a travel lens for daylight shooting (& I liked that it was lighter & used 40.5mm filters), but I've found it easier just to carry 1 fast lens. I am using it more now w/the M 240 on account of its acceptable ISO 2500-3200 performance. Anyone using the limited edition collapsible Konica 50mm f2.4 on an M9 or M240?

mbc 1944 Posted April 8, 2015 Share #4 Posted April 8, 2015 Can you safely collapse the lens on an M240 without harming the sensor? Michael Quote Link to post Share on other sites More sharing options...

ynp Posted April 8, 2015 Share #7 Posted April 8, 2015 Advertisement (gone after registration) Can you also do so without harming the shutter? Yes. I use the Konica on my MP3 and M9. The lens cannot be used collapsed on the M5. 1 Quote Link to post Share on other sites More sharing options...
Raid Amin Posted March 9, 2018 Share #8 Posted March 9, 2018 This is a wonderful lens overall. I use it on my M8 and M9 cameras. 1 Quote Link to post Share on other sites More sharing options...
Ecar Posted March 9, 2018 Share #9 Posted March 9, 2018 Funny that you are resurrecting this topic, Raid. Actually, I bought another one of these only a couple of months ago, after having briefly owned (and sold) a previous copy several years ago. The price was very good (it came with a Dual 21-35) and I figured I'd give it a second chance. I have never been a big fan of the Hexanons, with the possible exception of the UC-Hex 35/2 that's beautifully built (and that I kind of regret having sold as well). Anyway, to make a long story short, I still find the 50/2.4 somewhat underwhelming, especially compared to the 50/2.8 Elmar-M: hard to explain, but the Konica is just *meh*, without the color richness and balanced contrast of the Elmar-M. To put it differently: it's not as good as comparable "modern" lenses and does not have the character of vintage glass. But that's just me. The focus tab is nice, though. On a separate note: I haven't found time to play with it properly yet, but the Dual may improve my opinion of Konica lenses . Quote Link to post Share on other sites More sharing options...
Raid Amin Posted March 10, 2018 Share #10 Posted March 10, 2018 I have never tried out a dual lens, so I don't know what you will get. I have also an Elmar 50/2.8, which is a beautiful lens. The Hexanon 50/2.4 is a sharper lens, though. 2 Quote Link to post Share on other sites More sharing options...

farnz Posted September 30, 2018 Share #13 Posted September 30, 2018 Is this actually the same lens as the Konishiroku 50/2.4? Pete. Quote Link to post Share on other sites More sharing options...
Ecar Posted September 30, 2018 Share #14 Posted September 30, 2018 Is this actually the same lens as the Konishiroku 50/2.4? Pete. Interesting question. AFAIK, there's no 50/2.4 lens labeled Konishiroku (they made only very few lenses in LTM in the 50's). However, Konishiroku was the predecessor of Konica, which, in turn, later merged with Minolta. The Konica Hexanon 50/2.4 is a collapsible Limited Edition lens in screw mount that was manufactured at the turn of the millennium. Quote Link to post Share on other sites More sharing options...
Raid Amin Posted September 30, 2018 Share #15 Posted September 30, 2018 It may be one of the sharpest 50mm ltm lenses around. I waited for years until I bought one. 2 Quote Link to post Share on other sites More sharing options...

Thanks, Ecar, I recall seeing a Konishiroku 50/2.4 for sale a few years ago and nearly pulled the trigger but I already had fourteen 50 mm lenses at that stage so discretion became the better part of valour.

Summicron35 Posted August 24, 2020 Share #17 Posted August 24, 2020 I have this lens almost permanently on my silver 0.85 M7, and sometimes when film developing is inconvenient I wear it on the silver M9-P; colors go well together with these bodies. More importantly I have gotten really great results with this collapsible lens. Great colors and contrast, and I prefer it to the Elmar - Highly recommended! 2 Quote Link to post Share on other sites More sharing options...
paulleica Posted April 30, 2022 Share #18 Posted April 30, 2022 I have just bought one too. When you use it on the SL2 compared to the Elmar-M (I have the silver one) you can see very clearly how much superior the Hexanon is to the Elmar. Does anyone have more information about the lens construction, for example a cross-sectional view? Quote Link to post Share on other sites More sharing options...
