Affordable close-up rig?

[Paul Howell]

I'm planning to be hand-holding for most of this (it's close-ups of body parts of strangers, so a tripod setup is out,

In you price range I would use a Mamyia C220 but get a body then a 105mm 3.5 if still within budget maybe a prism finder.

If you think you are going to photograph a field of diagonal about 6" or 150mm: that is a magnification of about m = 1:4 on 35mm, and 1:2 on 6x6.

You will have a lens to subject distance of about d_object = f * (1 + 1/m), so for "normal" focal length lenses of 50mm and 80mm, that's about 250mm and 240mm respectively. IOW if you use normal length lenses on both formats, the lens to subject distance doesn't change much, which makes sense since they both have "normal" angles of view.

If you use longer-than-normal focal length lenses, you gain more working distance, but you need a lot of extension (focus travel or bellows).

I think this distance is about at the close limit of Rolleinars, and attainable with a Mamiya C with the 80mm lens, but not with the longer lenses like 135 or 180mm. Attached is a table from a Mamiya C manual that shows the minimum field size achievable with each lens.

For close ups of people (body art?) where you have a 3-d, not perfectly still, subject and are hand holding, I'd really be concerned about speed of operation and of parallax error in focusing, that is focusing on some spot that isn't quite where the taking lens is pointed.

I understand the desire not to buy more stuff than one needs, but there are good reasons why people use SLRs for close up work. I think either a parallax compensated close up like the Rolleinar, or an SLR with a normal lens + close up, or an actual macro lens, is indicated. If you did look at medium format SLRs, they unfortunately aren't cheap any more, but MF macro lenses are often surprisingly not overpriced (I suppose they are in less demand from the "must have fast lenses for blur" users).

Ahh thanks for the field of view charts (and @runswithsizzers for the rolleinar chart) that's exactly what I needed. I was looking into mamiya C's with longer lenses but looks like I need to go shorter.

I'm [generally, intellectually] curious about shooting sheet film, but I'm not set up at all to process or scan it and I think for this project it would be inappropriate (too slow, no tripod) - I was kinda thinking a horseman with the rotating back set up with a groundglass and a rollfilm holder might get it done (and wow I would love to have one), but that's for sure out of my budget on this project).

Probably whether I go mamiya C/rolleinar 3/or 35mm macro lens will just come down to what I can get the best deal on in the next week or two - I'll post back!

VERY helpful thoughts - some initial thoughts/responses:

I'm planning to be hand-holding for most of this (it's close-ups of body parts of strangers, so a tripod setup is out, I think that rules out any TLRs without at least some indication of parallax error as well as any rangefinders or press cameras). I'm not terribly concerned about the different-angle-of-view problem of a TLR as long as I'm not mangling the framing. It also seems like if I could get one of the longer lenses (the 180 seems relatively available) on a mamiya C33/C330 that might help to minimize the angle-of-view difference since I'd be further from the subject.

Flat field of a true macro lens is also not required.

Image-quality wise, 35mm would be just fine (I'm not planning on making huge prints), but I was hoping to be able to contact print 6x6 (or bigger) negs. If i change my mind and go 35mm, I'll just grab something with at least 1:4 for my SRT-Super, any ole boring zoom lens or MF macro prime would probably be fine for this (but why do that when I could be having FUN with medium format!!?!?!).
able to get a full kit for much under $400

TLR? Handheld? Stupid, possibly insane.

Give what you need to accomplish, the ideal rig would be a 35mm SLR with a macro lens that will focus to 1:2 on its own mount and flash illumination. Autofocus would be helpful but is not necessary; just dial the magnification wanted and focus by teetering in and out. TTL auto flash would be helpful, but I've done this for > 50 years with small fixed output flashes; I took calibration shots to find the right aperture given magnification and film speed, made a table. Depending on working distance desired, lens focal length >= 50 mm. Around 100 mm is usually preferable.

If you have no gear, buy used. I'm a Nikon person, haven't shopped older Nikon digital SLRs recently. One of my friends who used Canon equipment died recently. I've seen thousands of his macro shots taken with micro 4/3 (I think) digital Canon SLRs (EOS Rebel T5i, EOS 20D); the shots he kept are all publication quality. These cameras and macro lenses to fit them (friend used a 50/2.5 Canon AF macro) are quite inexpensive these days. No reason to get the latest most best most expensive, obsolete digital gear is better than good enough.
