Isn't miscalibration an issue with the Zeiss Sonnars as well? Not that I own one but plenty of threads just here noting frustration with it.

Infrequent, I think it's not so much that the ZM 50/1.5 comes miscalibrated, but that it front focuses. Mine focuses fine at f/2.2 (ie rangefinder patch is accurate) and smaller, but front focuses by 5cm or so at larger than f/2.2. Others report optimisation at f/1.5.

Ah! Thanks for the clarification. I saw an eBay listing recently noting optimisation at f/2.8 so there clearly seems to be a way to dial in a preference or the factory setting has changed over time. Assuming the price prevents 7artisans from doing a better job with this.

You get what you pay for.
A new 50mm RF lens with a 1.1 max aperture cannot be bought these days for $350 other than the 7Artisans lens. The CV 50/1.1 costs twice as much. Even the J-3+ costs twice as much. People who collect and admire Sonnar design lenses may be tempted to get such a 7Artisans lens. I nearly ordered one myself, but then I decided to wait and see what users of the new lens write about it.
If many people order such a lens and if they do not return it, the cost may go up soon.

The ZM Sonnar is either optimized at 1.5 or 2.8. Zeiss changed from 2.8 to 1.5 over the years. Some people have sent their 2.8 optimized lens to Zeiss to be optimized at 1.5. Great lens when you get it in focus, but a maddening experience for me on the M9.

I compare (for my own purposes) the 50/1.1 7Artisans with my used CV 50/1.5 ltm. The cost of a used CV 50/1.5 ltm is not much higher than what a new 7Artisans 50/1.1 costs. The CV lens is vastly superior in all aspects, unless you cannot accept a lens with max aperture 1.5 and not 1.1.

I never understood those 50 1.4/1.5 vs 1.1/1.2 debates. The difference is huge. Here is absolutely nothing to compare. You need 1.1/1.2 or you take safe route with 1.4/1.5......
Even Summicrons 50 are focus shifting. My Rigid was doing it and I googled thread here at RFF once.
From what I have seen, read here and at another forums... I'm not sure if manufacturer has this lens tested on FF dRF even at R&D stage. It looks like they only did it on crop body with LV via M adapter.
But the idea with DIY alignment is neat. If not revolutionary. Many cameras have RF calibrated differently and at f1.1 it makes big difference.

Ah. So it's a digital lens with an m mount. Obviously my igg-nerntz shows I'm a film shooter.
Maybe I should take the digital plunge and grab an old NEX-7 or A6000....

For those who want to buy this lens to use on a mirrorless camera, there is another Chinese 50mm f1.1 lens (I think Kamlan it's what it's called) that costs only $150.

AFAIK, the Kamlan is for APS-C and does not have a large enough image-circle for FF.

They have a cheap M 4/3 25/1.8 lens, I think.

Got it in today. These are straight jpgs from my X-Pro2 and have not been processed. Obligatory cat photos. The first one is at f/1.1 and the second one is at f/2.8. This lens may perform gangbusters on a crop sensor. I'll need to see how it does in low light to further evaluate but for right now it's pretty good to me. It's a heavy bugger too. I used the official M to Fuji adapter as well to mount it on the camera.

Lovely images, great looking green-eyed cat.

I weakened, and I placed an order for a silver one.

Cropped images will look better.

Depends on what a 'better' image looks like.

In the 1.1 shot of the bamboo fence, it is obvious that the lens is very weak (at 1.1) on the outer thirds of the frame. But for a portrait where it is centered, that may look great as one may want the image to soften up like that.
With a cropped sensor, you will lose that and only have an 'ok' in sharpness image. It seems cropping will lose the personality of the lens.

It's a cute little thing and will eventually produce some great images for a bunch of folks.
From what I can see from the few samples so far, it's not a lens that would add anything new to my set.
I have lenses that are clearly this fast and weak.
It's a useful look but not one I'm lacking.

I am planning to use it on the M9 for portraits.

I have other lenses too, but it is a "new toy" to play with. Isn't this part of life?😀
