First 7Artisans 35mm f/2 Lens Review


Recommended Posts

It not fair not be compared against the Summicron 35 ASPH, design, age, cost, quality controls and many more, but if it is close to the leica performance, WOW....

 

Chinese products are improving in quality, not only quantity, they are here to stay.

 

Wonder what it is their actual lens road map for the future.

Here's a handful of images shot on Tri-X with my M-A. I think the lens works well for people and on film. But it can still work for details as well.   Hello guest!

I did an adjustment for infinity focus today and confirmed that the thick bronze cam does indeed adjust infinity focus and now it's accurate. I also noticed that after adjusting it my focusing action was very tight from .7m to about 1.5m and I was concerned that I had done something wrong but after a tiny (and I do mean tiny) adjustment of the set screws it is at least back to how it felt from the box, if not slightly smoother.    Here's a quick snap as I was leaving work. I liked the light co

Mine was delivered today - Build quality - Solid - (More solid and robust feeling than my Summicron 50/2 V5 and similar to my VM 35/1.7). Smooth well damped focus and no aperture ring looseness that Emulsive noted.   Hello guest! Please register or sign in to view the hidden content. Hallo Gast! Du willst die Bilder sehen?

Well, checking more pictures and this fresh review Flickr samples...I'm not sure about Leica, but It is not so close by performance to Color Skopar and Nokton. Barrel distortions and swirl of bokeh. And it is not 35mm lens, it seems.

Awesome price and just right build, but optically....

Skopar is 2.5 but it is next to flawless lens (except it is boring

) and it is tiny and cute in M-mount. Nokton is 1.4 and it has less distortions and swirl. 

I'm currently using J-12 as second lens for M4-2, while my main 35 Leica aspherical lens is on M-E. It would be nice to update from flare catching J-12, but I'm not sure anymore I want this new lens.

So soon? What happened?

 

Well, I'd rather not comment until Malcolm has had a look at it but its an interesting lens. This includes the mechanical design which obviously is intended to work on an M rangefinder but is not the same as the mechanism fitted to a Leica lens. Building optics and designing the mechanics of a lens is not too difficult these days, however getting it all to work properly, reliably and effectively isn't quite as simple as it may seem. I have high hopes for the lens but at the same time I want to be sure of its pros and cons before I write anything substantial about it.

Fair enough. Look forward to your/Malcolm's feedback. I'm sure we'll learn a few interesting things.

I had ordered one from the second batch that Hamish made available. No word on shipping yet but I imagine it will be sometime soon. I'm not expecting it to be a perfect lens but I'm hopefully it'll be enjoyable enough on film for when I don't want to bring my Summilux FLE as that's my primary lens. 

 

The barrel distortion is indeed concerning but I don't think it's a deal-breaker for me. The bokeh is also "so-so" at times from some of the samples but then people say that about the Summilux FLE as well, and I also don't buy a lens specifically for its bokeh qualities. 

 

Anyways, I am glad to see that there are fairly inexpensive options becoming available, maybe it will push Cosina to revamp their Voigtlander lines in response (as they seem to be focusing on the Sony FE mount primarily of late.)

I already have

. Without wanting to pre-empt anything, there are various ways of designing the mechanics. Leica choose one which suits their ethos of high quality design best. It is a 'from the ground up' way of manufacturing. There are others. So, for example, it is possible to take any lens and put it into a Leica M RF coupled helicoil mount. But doing so gives options to both designer and production engineer. Some are probably easier and cheaper to make than others. Its a matter of trade offs. And of course there is that expensive business of quality control. This can add substantially to the cost of a lens. Manufacturing costs vary throughout the world as does the ethos behind what is being manufactured.

Thanks, Paul. The sort of design approach that you are hinting at would explain why it's easier for them to give users the possibility to adjust focus themselves. And reduce assembly costs.

I’m about to order one. Can anyone has the retail version kindly confirm the actual weight of the lens? I’m getting conflicted information about that. The spec sheet and even their sales people from China said it’s 320g. But the review from Leica rumours said it’s 205g, there’s even a picture of it on the scale. At 320g it’s completely useless to me. Thanks in advance.

Well- mine weighs in at 212g without the caps.

I finally got mine and it in fact weight only 205g. I can tell it’s lighter than my 11673 right the way when holding it in my hand. I got mine from 7 artisans online store and have it modified to be able to mount on CL and SL.

The 50 f1.1 I tried certainly needed modification.

Yes the 50 does. At first they listed on their page said the 35 also needs to be modified. Then I contacted their sales people to request a modified version, they said yes. When it arrived today I don’t see any signs of modification so I contacted them again. They confirmed that the 35 doesn’t need that. It works fine on my cl with the Leica adaptor and hawk’s close focus one. Don’t know about sl tho, cos I don’t have one.

What kind of modification is meant here? At the 50 and the new 35?

Do you have a link to the page?

Owning a non-digital Leica CL I know that certain collapsible lenses might touch and damage the cds-lightmeter, which slides in and out, at the CL and the M5.

So I was careful when mounting the new "china-cron" and a very old collapsible summicron 50 on my CL ... the rear lens is protuding ... but for my 7art 35mm on my CL I can report that there is no contact or damage to the lightmeter sensor.

My 35mm arrived today. My initial impressions are good, although my lens has a tight spot at about 1m, I'm going to use it for a while to see if it either loosens up or doesn't really bother me.

 

The lens comes with a focus chart and instruction on how to calibrate it. I ignored the instructions and just adjusted it until the RF patch lined up perfectly at infinity, a test will show me if that was the right thing to do.

 

I love the size and weight of the lens, after living with a DR Summicron this lens weighs nothing!
