A general thread comment: There is a lot of useful and interesting information in this thread. However…

While I understand how much fun it is for folks to post humongous images, not everyone is viewing on 27” monitors. (I sometimes do when I’m at my photography workstation, but that’s not where I do must online viewing.)

A few suggestions:

1. If the point is to show the image quality at 100% magnification, consider sharing some modest-sized crops that show this and, if necessary, linking to full images for those who also might be interested.

2. If the object is to share photographs as photographs (as opposed to test subjects), downsize them so that they are fully visible on at least a typical laptop screen if not a bit smaller. Again, a link to a huge online version that interested viewers could optionally click works.

Otherwise it is kind of like selling bananas only in lots of 300 units. I may want a banana, but I don’t want it badly enough to buy 300 of them and watch 295 go bad before I can eat them. If you want me to buy your bananas, offer them in a quantity I will buy.

Most of us aren’t going to manually scroll over on each of these gigantic files. Basically, we’re not going to look at them. Provide the images in a form that the typical viewer can access and offer the gigantic sizes as an option via a link or a click.

Thanks.

Here’s an example what I see on screen here in this thread in quite a few cases…

Beautiful shot and an example of how vignetting can be a nice touch.

Any guidance on using Mamiya 645 AF lenses via an adapter on the GFX? I have one, an APO 300 f4.5 that needs the camera to focus and change f stops.

I know these suck but I really do like the 28 Otus on GFX









This is more of a mental note to myself to use this more often. I was watching northern lights in AK and only had f4 lenses on me.

Jesus if those suck then I quit.

How much do you have to crop to totally get rid of the black corners? I see they're slightly visible in one of the shots. @Steve Spencer on page 1 says it cannot go above 24*36mm frames.

Thanks everyone for the kind words Zeiss gave me that lens in exchange for imagery for their advertising.

Here is the original uncropped beach photo:

Lucky you! It is a very impressive result! No doubt they were very very happy
A pity that Zeiss is not any longer active in consumer photography.
To bring the Otus to mirrorless format would have been a fantastic thing

I know the topic of adapters was discussed a couple years back, however I am curious specifically about the TechArt as they have revised theirs and made it FW upgradable. I ask mainly because the TechArt EF to GFX adapter is half the cost of the Fringer. I am wanting to get one, not sure how much I'll really use it, but still leaning towards the Fringer because it's verified to work seamlessly for both AF and AE. However before spending the extra coin I was wondering if there were any user-updates on the latest TecArt version? Thanks in advance for any info!

Steve, your comparison is fantastic and most interesting. Hasselblad and loxia are good lenses. Watching your comparisons, it looks like the advantage of GFX should be very minimal with the lenses stopped down. Probably the comparison between more modern bodies, say GFX 100s and A7RV would be similar. Thank you very much for sharing your experience!

Steve Spencer wrote:
My overall take is that in sharpness they are very close. The Loxia is perhaps a hair sharper/better contrast in the centre and the Hassy is a tiny bit better in the corner, but really there is not much to sharpness differences. The color and dynamic range, however, is more noticeable and it is better with the Fuji sensor especially in highlight recovery. The Sony shot could have had a bit less exposure, and they were taken a few minutes earlier and thus the light had a bit more dynamic range, so this test is less than definitive, but

I found this Minolta little beast could mantain very good charpness even slowing aperture down to f16, much better than many other 100-120s.

Interesting stuff. I have both the El-Nikkor N 50mm 2.8 and the 80mm 5.6. They both have M39 thread. No focus mechanism, so using these lenses on a GFX requires a helicoid adapter.

Thanks for that Aliexpress link. Browsing on Aliexpress it looks like there are various sizes helicoid adapters, to allow for infinity focus at various focal lengths. I will order the adapter for 80mm, assuming that the 50mm will focus beyond infinity on that adapter but that's ok for now.


So....

That Aliexpress Chinese noname '80mm' M39-GFX helicoid adapter doesn't focus to infinity.

And the 50mm enlarging lens doesn't entirely cover the GFX sensor.

BUT - the 80mm is VERY sharp... Wide open at 5.6 is sharper across the frame than stopped down to 8 or 11.


50S2, El-Nikkor 80mm 5.6 enlarging lens with helicoid adapter

wide open, 1/200 handheld. doesn't vignette because this is a medium format enlarging lens.

This was more a foreground and background blur test than anything. I left the vignetting uncorrected because I like it.

Topcor 58 f/1.8 set to f/2. I am surprised how much detail this 1960s lens can render on a GFX sensor at such wide apertures. Great contrast as well.

The flange back distance for the Nikkor EL 80mm f5.6 lens is 70mm, depending on your version.
So 26.7mm (gfx mount) + adapters should be less. You can get there with a M42 to gfx adapter (45.5mm back distance) and a 17-31mm focusing M42 helicoid and m42 to m39 adapter.
