I have one Wistar-W 150 which i like very much. As far as I know they are the same lenses as Osaka 6-lement and Congo Alto-W lenses. In short: manufactured by Congo in Japan. Some of them are 6/4...

Thank you all for giving your thoughts. Right now I don´t need more cameras, but when I saw a NEW Wista DX for that price on Q****y Camera I thought that it must be a good buy. If I don´t like it I...

Just a short question:
Is 749 USD a good price for a brand new Wista DX? Is it worth the extra cost vs Shen Hao or Tachihara?

Thank you very much, exactly what I was looking for. I hope I can help you next time.

Thank you very much!

I´m interested in buying/reading litterature about them Is there someone who has got such litterature?

First I want to thank you all who have helped me erlier on this site.
Now I have questions about the Symmetrigons (the 4/4 designs actually, not the older 6/4).
This is an interesting design, not...

I once owned a Rodenstock APO-Ronar 240/9 in a Compur 1 shutter from the early 80'ies. The shutter itself was the standard size, but it had an additional sign for showing the aperture setting, so it...

The problem with developers is R3:s special structure with 3 layers. Those who have tried it in Rollei´s developer, or Promicrol (for example) liked it very much. Those trying D-76 will most likely...

67 mm as far as I know.
Somewhat bigger and heavier than most other 210, but the same filter size.

Take a look at www.digitaltruth.com. Ther you can find data on Rollei IR400 as well as comparisations and reviews, which are very helpful. Some people think that the IR400 has got too weak IR...

The G4050 does scan 8x10 without problems. You can scan contact sheets and whatever you want without the templates, but, there need to be some free space on the top of the scanning glass (I think it...

Thank you for your answers.

I shoot 4x5, both colour and B&W, so I am interested in good contrast and sharpness.
And about coverage: I am a very recent convert to LF (I was shooting 6x7 before)...

Exactly what has gone wrong?
Does it stick on slower speed? Total lockup? Have the shutter blades jumped out of their positions?
I have disassembled some shutters and been able to fix them myself,...

I recently bought a APO-Ronar 240/9-lens (4/4 single coated, coverage 212 mm) in very good condition. Now to my problem: How does this lens compare to my Fujinon NM 210/5,6 (6/5 multicoated, coverage...

I have a Nikkor-W 150/5.6. and a short question: Does it cover 5x7"? I know that the litterature states the coverage to be 210, which will be very tight on 5x7, but at the same time I know that some...

Thank you for answering!

I have leaned towards the Fujinon myself, but I wanted to hear your opinions first, as the users most often knows best.

Does anyone have experience with these two lenses?
I have bought both of them (because of low price, shutters to fix...) but will only keep one of them. Which should I keep?
