Ecar Posted February 19, 2018 Share #41 Posted February 19, 2018 Advertisement (gone after registration) The one criticism of the APO I would make would be its hood. While the mechanics of the hood is clever (rotates out and locks), it is a tad too short. Messr. von Overgaard is presently selling vented hoods for the lens which seems of an ideal size. Cheap 39mm screw-in vented hoods can be found on eBay and work too. 1 Quote Link to post Share on other sites More sharing options...

james.liam Posted February 19, 2018 Share #42 Posted February 19, 2018 I guess if the cheap hood is vented, it ought to work as well. Sent from my iPhone using Tapatalk Quote Link to post Share on other sites More sharing options...
SiggiGun Posted February 19, 2018 Share #43 Posted February 19, 2018 Hi Do I need this lens ? NO! if you are an film M user. Do I need it if I am a digital M user? PERHAPS! Do I own this lens YES! I have owned a 50LUX and I replaced it by the 50AA. Realy booth are great lenses. YES the handling with the 50LUX is better but It is bigger on the other side. From a Image quality of view? Differences are, in my opinion, very very small. My lens was in Wetzlar 2 times for flare. For "normal" application a classic CRON or a PLANAR are cheaper and good options. I tried to compare the "boked" of different 50 lenses, here are some images https://siggigun.wordpress.com/2015/04/25/bokeh-bei-blende-2-0/ 2 Quote Link to post Share on other sites More sharing options...
jay968 Posted April 20, 2018 Share #44 Posted April 20, 2018 (edited) APO lenses have been around far longer than digital sensors. Their benefit is realized on film as much as on digital sensors. An APO lens better focuses all 3 primary colors on the same plane than a non APO lens. This results in less aberrations. The 50 Summilux ASPH has been said to actually also be an APO design but Leica never deemed it as such. In any comparison I have ever seen between the Summilux and the 50 APO, I have seen hardly any difference whatsoever between the two other than the fact that the 50 APO seems to handle edges a slight bit better. Don't get me wrong, I would love to own the 50AA, but at twice the price? Not sure its performance is double that of the Summilux.

Jon Warwick Posted April 20, 2018 Share #45 Posted April 20, 2018 I have the 50 APO. And v5 Summicron. Edge to edge sharpness / no field curvature / higher contrast / richer colours are the key benefits of the 50 APO. Resolution in the centre on low megapixel cameras like the M240 / M10 look near identical at (say) f5.6, however. In contrast, i DO see resolution benefits that are apparent on the M246 Monochrom due its non-Bayer sensor (ie effectively much higher resolution sensor). The Monochrom and 50 APO is an incredibly lossless chain when it comes to detail capture. Quite extraordinary for large prints, in fact. Finally I partly see the 50 APO as being beneficial when higher resolution colour cameras (whether SL or M) eventually emerge, even if benefits to centre resolution on low resolution 24mp colour cameras is currently de minimis. 2 Quote Link to post Share on other sites More sharing options...

ibramr Posted April 24, 2018 Share #48 Posted April 24, 2018 All, I love this forum and the info you all provide. Edited ........ Also - does anyone know after what serial number the flare problem was fixed? Thanks! Greetings. Here are the three reasons to buy the APO. Firstly, we only live once. Secondly, it is that good (and it will shine more on the Monochrom). And thirdly, you can. Enjoy in good health. Quote Link to post Share on other sites More sharing options...
romanus53 Posted April 24, 2018 Share #49 Posted April 24, 2018 Had the 50 lux asph and the 50 Elmar-M which had the same look to me on comparable f-stops. Sold both to get the 50 APO, main difference to me is the smooth bokeh of the 50 apo, found the behaviour of the other two mentiond lenses busy in comaprison. Maybe the 50 apo is a little more perfect in other Terms but that's not important. If you once have it you always have the good feeling that you can grab the best lens arround. Still I like playing around with other older 50ies. I dislike the Hood of the 50 apo, don't need the speed of the 50 lux, miss the compact size of the 50 Elmar-M (chrome version has better building finsh). You can't have enough 50ies so don't make that mistake and sell the 50 apo if you once have it, the loss of money hurts. Quote Link to post Share on other sites More sharing options...
B-A-C Posted April 25, 2018 Author Share #50 Posted April 25, 2018 I'm going to stay with the Lux for now. It's just so good for me on film. In the future I can see splurging for the APO, perhaps with a Monochrom. 1 Quote Link to post Share on other sites More sharing options...

In the future I can see splurging for the APO, perhaps with a Monochrom. B-A-C, This is a very good decision, particularly, if you are in your forties—you still have time to consider. If you are like me in mid sixties, then, I am not so sure. Mind you, the Summilux is a superb lens and should give you many, many long years of wonderful service. Enjoy in good health. 1 Quote Link to post Share on other sites More sharing options...
delta100 Posted April 25, 2018 Share #52 Posted April 25, 2018 Its not about do I need a 50 APO! Its about the concept of your work and the image. Robert Frank or HCB did not think on a GAS level. Use what you have! Quote Link to post Share on other sites More sharing options...
efreed2754 Posted April 26, 2018 Share #53 Posted April 26, 2018 Agree with ibramr’s comments. This is not a need rather than an enjoyment affordability balance. Being retired and over 70, decided this month to upgrade and enjoy/enhance my photography. Yes a IIIf and M user since early 1970s. First traded in M240 for M10. There were some nice enhancements including focusing and Viso improvements. Also missed option to see what each lens covers due to my frequent concert pics from a fixed position with varying ensembles. Then began reading reviews again about the 50 APO and thought “what the heck.” So traded in my pristine 50 Lux and mint 50 Summicron (current lens formula but original design with box). Loved the Lux having not much use for 50s until bought this one new several years ago. It changed my views of the 50. Oh APO was a year old in mint condition. Net outlay reasonable. Having only shot a few concerts thus far am delighted with the APO and the M10. Photos have improved and getting many compliments didn’t get before. Credit both the M10 and APO. Lux was wonderful. APO just special. Using it gives me more confidence and enjoyment. Priceless, 2 Quote Link to post Share on other sites More sharing options...
leonasj Posted April 27, 2018 Share #54 Posted April 27, 2018 i had both,apo50 and asph50/1,4 ,sold apo50, keep summilux it is same sharp at f2 ,sharper at f4 and has better bokeh Quote Link to post Share on other sites More sharing options...

Your contentions are incorrect (sharpness) and subjective ('bokeh'). 1 Quote Link to post Share on other sites More sharing options...
01af Posted April 27, 2018 Share #57 Posted April 27, 2018 I had both, Apo-Summicron-M 50 Asph and Summilux-M 50 Asph, sold Apo-Summicron, keep Summilux, it is as sharp at f/2, sharper at f/4, and has better bokeh. I suspect you were confusing your test shots. 5 Quote Link to post Share on other sites More sharing options...

In the first article ‚about 2300 lines‘ are mentioned for the Summilux and in the original one ‚only’ 2080 lines. Thus, the APO is way superior in average sharpness! I agree that the bokeh might be more pleasing (dreamy) with the Summilux (also a question of taste). However, one also cannot neglect the much(!) higher contrast and unsurpassed clarity of the focused part of an APO image. I have to admit that this is my impression based on only about 50 photos with both lenses. However, just look at the photos of Sean Sweeney on Flickr and you will immediately notice the difference! It is even more pronounced in reality. That said, I am still not sure if I should opt to buy the APO as I am currently loving portrait photography. This may benefit more from the Summilux or even Noctilux!? Edited April 28, 2018 by FrankX 1 Quote Link to post Share on other sites More sharing options...
