These Korean noname mirror lenses become dirt cheap. Just get a new one. $250 for 900mm f8.
Armin, It's a very hard work of patience. You must have spared enormous time for this work. Thanks for your contribution to the society. Of course it is hard to tell the differences in the way you...
I second dave_whatever. Since the nodal point is in the front of the lens the tilts and swings shall be performed in conjuction with rises and shifts respectively. If you cant resist buying a tele,...
Thanks for the correction Bob.
Thanks for expressing your thoughts on this topic Lynn. I was a little unclear and i am sure you will agree with me when you learn my conditions. Well as i have mentioned up there somewhere, for...
Very nice idea. I am an anti-apple. But there are some free audio recorder applications with wavefrom editing for Androids. So if the shutter sound is recorded i believe the duration can be...
I just would like to do the work properly.
Anyways.. Just came accross with this one in the unspeakable auction site. Well it seems like a little bit beaten but still a bargain as mentioned....
Yes Bob, I guess coins will glitter at the end of the day.
Dan Hi, It is best noticed on the histogram. When i shoot with a MC lens such as a Macro Symmar the whole available dynamic range of the scanback (even beyond it's capacity) is used. At correct...
I know the 150mm APO Ronar but is there any between 180-210. I have a 120 Macro Symmar that i can utilize for certain objects but for some larger ones i need something longer. Ideally 180.
I run a...
yes you are right. enlarger lenses are an option however yet most enlarger lenses are either not coated or single coated. rodagon d for instance is perfect for this job. but the longest one is 120mm...
G Clarons are low in contrast . I have tested both 150 and 210.
Since i shoot with a scanback i don't need a shutter at all. A barrel lens provided it's MC should do my job just as perfect. How...
OK. I need a multicoated lens with a focal length around 180-210mm for close up work. I see that almost all of the lenses that i have tested get perfectly sharp at apertures like f16~22. So sharpness...
here is a previous discussion on this very topic.
OK I've done some searching and now came to know that the G Clarons had been produced in two optical designs. The older ones are in 6 elements 2 groups Dagor type and the newer ones are in 6 elements...
I thought all G Claron 210s should be fine with #1 size shutters. Mine is ok with the rear cell but the front cell is slightly smaller.
Not all G Clarons are created equal?
It's not the lens but the shutter where you have the problem. actually it's a very simple repair task but in case it would be costly to find the right person and to deliver the lens both ways, just...
For proper 180mm macros from Rodenstock and Schneider people ask for 4 digit figures up to $3K but the ones that i saw really changing hands went for $500 or so. Nikkor AM ED (120 or 210) likewise....
Well i guess it's not that rare as mentioned in the listing in the first post.
Here is another one with the same Planar design but not the T version. The older crimson (single..?) coating i guess. Considerably cheaper. Still i think for LF a speedy 135mm hasn't got the use...
If you are sure that this fault is between two cemented elements does it really matter what it is? I see two options here
1) You have to have it separated and recemented (alternatively you may try...
I think the loss of sharpness is a mutual product of diffraction (f22 -> f32) and simplification of the optical system. Nothing unexpected here.
My Linhof Technorama 617 has the very lens that you mention on it.
Armin,
With their pentagon apertures I don't expect these process lenses to produce bokeh as nice as a lens with almost circular aperture; still i would love to see your bokeh performance test...
These are real life shootings. Unless i shoot resolution charts (i am sure some people here will find them extra boring) it wouldn't be possible to comment on meainingful lpm values. Besides 8400...
Hi. I believe all lenses are diffraction limited regardless they are process lenses or not. And one of the results of this test is the visible effect of diffraction clearly noticeable in all f45...
A Konica Hexanon GR-ii 210 9 would do the same job just perfectly. These are fantastic lenses. I have tested the 150mm one and it was better than the G Claron 150 9. Just yesterday a 210 9 hexanon...
I understand some of you guys have browser locking up issue. I am sorry for that. However the total size of the images in this thread is no more than 35MB. This shouldn't be a big deal for a moderate...
Hi Dan,
Thanks for your understanding. :) It took some time but it was really fun. I believe an old dusty Technorama with many scratches has enough detail. No..? (i.e. check the blue dust in the...

I have been working on this for some time now. I know there is a long debate going on regarding process lenses (AKA flat field lenses) when used for general purpose or product photography. In this...
Jack, what black paint did you use on the sides after recementing..?
I have tested the following lenses and have seen distinguisable and measurable differences between both resolution and contrast performances at M ~ 1:2.5
