Anybody tried this? It covers 5X7 with lots of movement. Thought I'd try it out this weekend but was wondering if anyone else had tried it. Thanks.

Apologies in advance for this being a bit off-topic, but: I'm waiting delivery of a 150mm G Claron lens in a Compur 0 shutter to use on a 612 Fotoman. Could you suggest any tests of the lens given this camera setup once I have it in hand?

Thanks in advance for your replies.

Give it a try but I used my 150 on my 5x7 and when photographing an old engine house with a rather tall chimney a couple of weeks ago I did get some vignetting. It's gotta be worth a try though, It should work for less extreme shots.
Best wishes,
Pete.

Will closing down the shutter reduce the vignetting?

I have used this lens a bit on 58"/1318cm and thanks to my style of shooting recently (landscapes with a lot of clouds - some rise), I have run out of coverage quite often. But if I'm modest with the movements, it's an excellent lens.

Stopping it down helps a bit (well, I don't know exactly to what amount, I have not done any rigorous testing. But when I'm using some rise with it, I always stop down to have a larger IC if possible...).

Those shots here on my website (http://www.vasina.net/?tag=g-claron-150mm) are done with a G-Claron 150mm.

Im looking forward to this answer as well- I would love to add a 4x10 lens of approx this focal length without going broke. I realize there are quite a few uncoated gems that probably work great for B&W work, but I shoot primarily color and often facing the sun somewhat so coatings are kind of a must for me.

I know everyone says that Schneider's coverage claims are conservative, but still and all 4x10 (diagonal 274 mm) has to be a stretch for the 150/9 G-Claron. Schneider claims 189 mm for the plasmat type, 191 mm for the dagor type, at f/22 at infinity.

I'm afraid we've fallen into treating "illuminates" as "covers."

Cheers,

Dan

OK, then I will give it a shot this weekend and report back.

Are we talking the factory mounted or the user mounted ones? It'll light 8x10 plus a bit. I wouldn't claim the corners are sharp but they sure weren't dark straight on. I forget how much movement before they went dark.

Oh BTW the Fuji-W isn't any more expensive normally. Faster. Similar size. Same sort of coverage.

How does the Fuji-W do with color slide films? Is it coated?

Even a little 90mm Angulon will illuminate a sheet of 8X10 film. The portion that is usable as "sharp" will be a little bigger than what is needed for a 4x5 sheet of film. Some of the earlier versions of this lens can't really claim even that.

The high coverage model is single coated.
