My first post, thanks for such a great resource, it seems like a great place to ‘hang out’.
So here’s what I am trying to figure out:
I would like to purchase a tech camera, most likely the Cambo WRS and use it with a mfd back for flat stitching. I am trying to figure out what lens to start with.
Apologies for 35mm terminology but I am a bit of a large format virgin . I want to achieve a field of view similar to 24 or 28mm lens on 35 full frame.
So bearing in mind that I will be stitching to achieve this field of view what lens is the best to start with? I have been looking at the image circle of the various Cambo mounted optics and they vary a bit so I am unsure if they are all suitable for stitching. I am thinking that the “WTS Tilt/Swing Lenspanel with Digitar 72 mm Lens” is the right one, its stated on Cambo’s site that the “Image circle of lens at f/11: 90mm”. But a 90mm image circle won’t give enough coverage to use the full area available for flat stitching, so what do I not understand here? Does the image circle expand at smaller apertures?
I am considering purchasing a used Sinar 54 LV back for this project. Are there any issues I should be aware of with using the sinar on the WRS? I expect to have to have to use lens cast calibration frames but other than that, I am in the dark, so to speak with regard to other potential issues.
Finally, focusing. After reading Joseph Holmes’ article on ‘MFD Precision’, I am wondering if the addition of the new Tilt/Swing lenspanel offered by cambo will add further to focusing issues, is anyone using the cambo WDS-619 ground glass for focusing? Any thoughts on this Cambo combo?
Sorry for the meandering post, to summarize, I am considering:
Digitar 72 mm Lens (possibly with tilt/swing option)
Cambo WDS619 Ground Glass
Sinar 54 LV (for stitching)
Any thoughts, suggestions or alternatives greatly appreciated,
