Ektar f7.7 203mm lens hood

[steve_feldman2]

Hi group,

 

I have a beautiful Kodak Ektar f7.7 203mm lens on my Crown Graphic.

I'm very pleased with it's performance but I have one nagging

problem. No filter threads on the front element.

 

I have a 1-1/4" inside diameter Series VI slip-on, adapter ring, hood

and filters for a 90mm lens. By bending the "tangs" inward slightly

it's a perfect fit for that lens. The 90mm lens has a o.d. of 1-3/16"

so the inward bend is no big deal but the 203 is a 1-5/16" o.d. I

feel that bending the tangs outward slightly may be counter

productive.

 

I know that the Series VI slip-on hoods were (are) available in many

different diameters. So, should I get another 1-1/4 and bend outward

or shop around for a slightly larger o.d. and bend inward?

 

What to do - what to do.

 

Thanks for your opinions.

Steve I had a similar situation with a 210mm Kowa Graphic lens. I took a normal step up ring that was slightly too small to slip over the OD and removed material until with heat it would slip on. When it cools it is a semi-permanent fit with a useable thread for regular modern filters. From a collectors point of view perhaps that kind of "kluge" would decrease value, but I'm strictly a user.

Hi -- what is the circle of good definition on your 210 Kowa Graphic. Can it cover an 8x10 as rumor has it?

 

Thanks

For Paul: I'll have to shine it on a sheet of 11X14 and get you a better answer but I do recall that I was kind of dis-appointed that it's really not much different than the G-Claron. Covers with a few mm to spare at f22 and smaller. 330ish is likely an accurate guess.

I use a 33mm slip-on series VI adapter on my 203 ektar, with a step-up for series VII filters.

Steve,

 

Just ask Steve Grimes to make an adapter for you. It's worth the money.

 

Paul,

 

Kowa Graphic wide angle 210mm will cover 8x10 (IC about 380mm). It's a small lens in Copal #1. The lens was first called Computar, then Apo-Kyvytar, then Kowa Graphic WA. The company changed several ownerships. It's a hard to find lens. Cheers,

I'm guessing there is a difference between the Kowa Graphic 210 f9 and the Kowa WA 210?

Why not just buy the right adapter if you can. Try Midwest Photo

and see what they have. I also have a dealer that's pretty close

and they have a supply of different adapters that I can check for

you.
