Rodenstock Grandagon 75/4.5 for 6x12, 6x17?

[buggz]

Hello,
Would this lens be a good choice for a 6x12 roll film back on a Sinar F2 4x5?
I am thinking of getting a 6x17 back also.
What are the differences between an N model of this lens and the non -N model?
Would this lens require a center filter?

Yes, I have searched, and searched, but I get conflicting information.
I just thought I'd ask the experts here.

[StoneNYC]

I can't answer the differences part, but I owned a Grandagon 75mm 4.5 -N "green stripe" version.

It worked fine on 4x5 so I don't see why it shouldn't work fine for 6x12, and although it doesn't quite illuminate 5x7 images because of the corners, I suspect you should be able to get away with using it for 6x17, however you'll most likely have light falloff toward the edges. I would do the math on the listed image circle and that should give you a good idea, sorry I sold mine so I can't check.

Dan, thank you for posting these.

It'll be fine for 6x17 but it won't work (focus) with the extension type backs needed to convert a 5x4 camera to use 6x17. You may need a recessed board on the Sinar to ise a 75mm anyway for 5x4 and 6x12.

Great information, got the Rodenstock brochure information, now to read it.
Thanks!

Hmm, would a 90mm be better?
I really don't know how wide I need, nor want.
Thinking of panoramic vistas, or something...

90 has historically been the "standard" wide lens for 6x17cm. It is quite wide, but not stupidly so (i.e. you rarely have to worry about getting tripod leg(s) in shot!)

The widest lens that reports as being sufficient to sharply cover 6x17cm (nominal) is Schneider's 72mm Super Angulon XL. Bit of a tricky lens to use, but worth the effort if you see the world this wide!

[Carsten Wolff]

I have occasionally used the 75mm f/4.5 SW-Nikkor on 6x17....pretty tight. On paper it has a slightly larger IC than the Grandagon. I mostly use 90 to 108mm in 6x17 wide.

It's a personal choice I had a 90mm SA as well as a 75mm SA for my Gaoersi 617 camera, I found I never used the 90mm and it's sat idle. I don't find the 75mm particularly wide in terms of the areas of landscape I shoot, it's close to using a 150mm with 5x4 or my TLRs on 120 in the horizontal aspect. In big wide open spaces then it may well be different.

Ian,

I'm questioning weather you er'd?

I say this as for horizontal view, a 6x17 is 5x7 with the top and bottom cut off (essentially) so how you think 75mm on 6x17 is anywhere near close as 150mm on 4x5 makes no sense to me.

If you had said 150mm on 8x10 is close to 75mm on 6x17, that would make a little more sense (though really 75mm on 6x17 is closer to 120mm on 8x10).

Maybe I missed something or maybe you said it backward?

[IanG]

Stone, I did use the word Horizontal when I meant Vertical, my mistake, it should have been:

I don't find the 75mm particularly wide in terms of the areas of landscape I shoot, it's close to using a 150mm with 5x4 or my TLRs on 120 in the vertical aspect. In big wide open spaces then it may well be different.

75/80mm lens is standard on a 6x6 camera, so the vertical aspect is similar from the same position whether you are shooting 6x6, 6x12 or 6x17 with a 75mm lens. So I think of a panoramic camera in terms of the vertical aspect first and then the wide panoramic horizontal aspect second. It's just my way of working, of course you could work the other way around.

If I was shooting 10x4 panoramas with my 10x8 camera then yes I'd want something slightly wider than a 150mm.

Ahh!!! That makes perfect sense!

I find the 150mm very wide, I can't really see a reason to go wider, there was a nice nikon 110m or 120mm at a fair price a few weeks ago that covered 8x10 and I decided I really just don't need it that wide for any of my work, however I DO know people who make amazing images for such a wide setup, I just can't seem to do it, I gravitate to the 90mm (4x5) or 210mm (8x10) more than anything for wide.

A few examples (not my best work just examples).

Examples 8x10 cropped to 4x10 (note 4x10 is slightly less wide horizontally and more high vertically than 6x17 but still helps visualize for the OP I think)

Hi,
Do you need a center filter for the S.A. 75mm or the Grandagon 75km?

[djdister]

Hi,
Do you need a center filter for the S.A. 75mm or the Grandagon 75km?

I've used the Nikkor-SW 75mm on 4x5 and 5x7 without a center filter and barely see any ill effects...

[StoneNYC]

Hi,

I never found a need for it on my 75mm Grandagon-N on 4x5, I found it much better than my 150 SS XL on 8x10.

A vagrant broke into my house about a year ago, he was cold and made a fire in the attic. I figured it was a good opportunity to take pictures in a burnt house legally. I don't live there anymore.

[buggz]

Wow, 75 looks really wide.
Perhaps, I'll get a 90 first, then go from there.
Thanks to everyone for the information and a great forum!

90's are also MUCH cheaper ;)

The apparent wideness is deceptive, it's totally down to the subject and and the camera/lens position and how you're filling the frame.

So this is a 75mm shot, using my 6x17.

In comparison this is a 65mm shot on 5x4.

http://lostlabours.co.uk/images/lydney.jpg

I would definitely get a 90mm anyway, it's my second most used focal length for 5x4, the 65mm get used when there's no other way of getting the image I want. The 75mm is fixed to the Gaoersi cone I'd like to use it with the 5x4 cameras as well as it has better coverage copared to the 65mm.

Hi Ian,
What 90mm do you use? Rosie or Schneider?

Hi Ian,

I use a Rodenstock 90mm f6.8 Grandagon most of the time, but when in Turkey I shoot with a 90mm f6.8 Angulon. I also have a Schneider 90mm f5.6 Super Angulon sat idle at the moment but I think it'll become part of my 7x5 kit.

All three are very very capable lenses, coverage is tight with the Angulon on 5x4 but it's a sharp lens, small & light, important in the heat in Turkey.

Ian

[cyron123]

Ian,
thank you. What do you say about the Rodie Grandagon 90mm 4.5? Is is a bigger lens. And in my opinion (as a landscape shooter) the 4.5 aperature is not really important for me. What is your opinion? Thanx...
cyron

[IanG]

Yes the 90mm f4.5 Grandagon is a bigger lens, I've never found the f6.8 aperture a problem with my Grandagon. Given a choice I'd buy a faster 75mm though as it#s not quite as easy to focus.

Very good point.
