FrozenInTime Posted July 17, 2017 Share #161 Posted July 17, 2017 Advertisement (gone after registration) My first disappointment with the lens: Today I took a lot of photos at the local ( Duncan's Mills ) civil war re-enactment. About half way through the fourth film, I noticed play in the focus ring. Seems like the three grub/set screws visible on the focus ring need tightened - I've had to order a set of tiny allen keys :-( Link to post Share on other sites More sharing options...
Advertisement Posted July 17, 2017 Posted July 17, 2017 Hi FrozenInTime, Take a look here 7artisans 50mm F1.1 Leica M Mount. I'm sure you'll find what you were looking for!
rramesh Posted July 17, 2017 Share #162 Posted July 17, 2017 Interesting that the image of 6 bit coding shows 5 dimples. https://leicarumors.com/2017/06/29/additional-info-on-the-cheap-chinese-7artisans-50mm-f1-1-lens-for-leica-m-mount.aspx/ Link to post Share on other sites More sharing options...

Worryingly, the heads of three existing screws show sign of blue Loctite. Perhaps the threads were not clean when first applied. Link to post Share on other sites More sharing options...

Ecar Posted July 17, 2017 Share #168 Posted July 17, 2017 Worryingly, the heads of three existing screws show sign of blue Loctite. Perhaps the threads were not clean when first applied. It’s a pain, but should be an easy fix. FWIW, It happened to me on a J-3+ within hours of unboxing. Actually one of the screws got lost and the other two became loose – no signs of Loctite. I couldn’t be bothered to send the lens back (or order Allen keys) and instead shipped it to Will van Manen along with a few other lenses that needed a CLA. Everything has been fine since. I must add that Will was graceful enough not to charge me. Link to post Share on other sites More sharing options...

About half way through the fourth film, I noticed play in the focus ring. Seems like the three grub/set screws visible on the focus ring need tightened - I've had to order a set of tiny allen keys :-( Can you put up a photo of the screws you plan to tight to remove the play from the focus ring? The video I posted, commented he had play in the focus ring. Would be nice to let him know there may be a solution. This link start at 1:27 where he talks about the play. Is this the same type of play you are talking about? He also links to some photos and his comments regarding the lens being soft wide open seem to in line with his photos. Do you feel the lens is unacceptably or more soft wide open than a typical fast prime? https://youtu.be/u8yobWGJX04?t=1m27s Link to post Share on other sites More sharing options...
FrozenInTime Posted July 20, 2017 Share #170 Posted July 20, 2017 Half a turn with a 0.9mm key on all three screws and the focus ring is solid again :-) 2 Link to post Share on other sites More sharing options...

Will test on digital just as soon as Leica get their act together and deliver a M10 ( it's getting close to 6 months since I traded in my M9 ) Link to post Share on other sites More sharing options...
jcblxpt Posted July 20, 2017 Share #172 Posted July 20, 2017 Hi to All, As promised, I'll try to post some pictures taken with the new 7artisans f: 1,1 lens, mainly wide open, except two or three images with aperture f: 5,6. In summary, the first impressions are : - Strong vignetting (only with one nd filter) - Strong flare and blur in the area outside the central image circle - Strong flare and softness of the image when in full aperture - Image acceptable, when closed down more than f: 5,6 Conclusion :Interesting to have, but with great limitationsFor the price, we can not ask more.

Best regards https://www.flickr.com/photos/117242615@N06/albums I just received my lens today and I totaly agree with your points. Try the lens at F1.4 and it sharpens up a little but the bokeh improves a lot plus it cuts down on the vailing flare (I know it is not vailing flare but that is the effect). A Noctilux it is not but it does have its own catheter. I have a corporate portrait shoot tomorrow so I am going to try the lens out and do an extra shot with it. 1 Link to post Share on other sites More sharing options...

David Millstein Posted July 20, 2017 Share #176 Posted July 20, 2017 I bought one, it seems reasonably well made but no click stops for the aperture settings, my first few images seem reasonably sharp and contrasty. It isn't a Summicron but it is only $379.00. Other photographers I have talked to like it a lot, especially for the money, and the allure of the speed is undeniable. It seems like a very nice value.

miguel Posted July 21, 2017 Share #178 Posted July 21, 2017 Agree with above points. I want to try on the m7 with a roll of black and white. I'm going to be shooting ISO 80 film so I'll need all the light I can get. https://flic.kr/p/WEY5ES Link to post Share on other sites More sharing options...
rramesh Posted July 21, 2017 Share #179 Posted July 21, 2017 (edited) I am quite disappointed with the negative criticism in this forum on 'things Chinese', and therefore must be mediocre or of poor quality. This is similar to the views on 'things Japanese' in the 70s and even 80s. There are many great products that come from China. Do note that it is among the world's top economies today. Yes, this lens is cheap. It does not use expensive or exotic materials in it's manufacturing process. But that does not have to equate with poor quality. The price-performance is exceptional. From what I have seen, the images are good. And at $500 plus it's a steal. I would have bought it were it not for the fact that I have a 50 lux and am now into FSU lenses for the M. Do note that the vast majority of people cannot discern the lens or the camera used when viewing a great photograph.

The criticism peaked in the Fifties. Regarding its place among economies yours is a general statement and ignores the many hazardous foods, building materials, and utter crap they have sold. It is true that inferior lenses have a certain charm. Go for it. 1 Link to post Share on other sites More sharing options...
