Kang Rinpoche S 600 F11.5 (Chinese Fujinon C 600mm )

We'll be looking forward to your comparisons!

I am open for suggestions on studio test methods.

Right now I am setting up Horseman triple standard 4X5 Optical Bench with lens hood and will shoot Plastica (mannequin) with printed objects wide open, f22 and beyond.

I will move to 8X10 tomorrow and consider 11X14 the next day.

Be reasonable...

Since I'm considering this lens for outdoor photography with my 8x10, I'd be most interested in how it performs under those conditions--overcast, bright sun, sun at an angle that could possibly cause flare, etc. But, I'll appreciate any results you post. Thank you.

Thanks for the update, Randy. As you start to shoot with this lens, general impressions are fine. Doing a truly objective lab comparison would be complicated, and mandate vac film holders or aerial image comparisons; and apparently, you're not interested in color performance. The Apo Nikkor is going to be far better corrected, regardless, but obviously way less convenient in the field. Nitpicky sharpness and apochromaticity isn't always a key factor in big film sizes anyway. And you don't have an original Fuji 600C to compare with, so no need to fuss about that question. Looks like the same shutter that was used for the Nikkor 450 M's. Have fun!

Shot the KangRinpoche S600 f 11.5 last night and processed the film in my first usage of my new darkroom. It's been almost 2 years since I had all the gear working. My move took a long time. I made mistakes. I had a empty water stop tank...

I lit the still life too hot with 2 big LED panels. The 4X5 Horseman was fully extended. I could not shoot the comparison lenses with this setup.

Today I will change to bigger camera with more bellows.

iPhone shots are for reference.

Ilford Delta 100 Epson V700 scanned with Vuescan Pro settings developed in 1/100 Rodinol gas burst. Not sharpened in PS, but contrast and brightness was adjusted. No spotting. No curves, no histogram trim.

The top food can in image has an invisible barcode way overlit.

I focused at f11.5 and did not refocus for f45. See paper notes in images.

Well, it clearly meets the minimum standard. Passes light, forms an image.

Did that model charge by the hour? The makeup looks a little heavy.

Plastica, $45 delivered, no returns

Loyal, never moves

Looks best dressed

Do you need the Tinder tag?

Randy, was the contrast adjustment the same for both images? If yes, what do you think accounts for the higher contrast of the f/45 image vs the f/11.5? Brightness between the two appears very similar.

Yes, exactly the same #'s in PS for brightness and contrast. Scanned together on 2 up Epson V750

Lighting was the same, exposures within 2 minutes and processed together on 4 up hangers.

I don't have an opinion.
