I'm the guy who commented on your 'gram about the handle and the folding focus hood. This is what I was talking about :

http://www.pentaxforums.com/accessoryreviews/pentax-67-folding-focusing-hood.html

I find it super useful for waist level stuff because it includes a magnifying loupe which is great for focusing. Also it's way lighter than the prism and you don't have to lug that stupid thing around.

Then again I'm a big ol noob so maybe you dont have any problems with these things.

You know, I never really shoot at waist level, but for my dumb Instagram gimmick poo poo, it may be better for a brighter image in the waist-level finder. I just wish I could have a brighter image without carrying one more thing around.

This table seems to be based on horizontal AOV. In my experience, comparing diagonals works better when you have different aspect ratios. In that case it'd be more like this:

Approximate equivalents of lens focal length
35mm 4x5 8x10
20mm 75mm 150mm
24mm 90mm 180mm

80mm 300mm 600mm
95mm 360mm 720mm
120mm 450mm 900mm

I've always most enjoyed using 35mm on 35mm film. The most directly comparable experience on 4x5 is my Nikkor-W 135mm and on 8x10 it's my Fujinon-W 250mm.

FWIW, 120mm on the 4x5 is very very close to 80mm on 6x6, just a bit wider only. Though I'm starting to enjoy using 150mm on the 4x5.

Yeah I basically pointed them at the same scene and saw that they captured the same scene, except that the 4x5 had more space on the long side.

I believe I may actually be the first person to take WPC down there? I know Hurley used glass negs/dry plates but I don't think WPC has been done down there before. With that intense UV and this fast etherless collodion I reckon I could get exposures in the 1/125 - 1/30 range at f.5.6

That would be rad getting to shoot wpc down there, perfect for low contrast landscapes. Just don't create an environmental emergency down there by spilling your silver bath on a penguin or something.

I do have a book of the first photographers that went down to Antarctica, and they shot dry-plate and were making carbon prints from them, definitely not wet plate.

Ah man if you get a chance to see that The Photograph and Australia exhibition I seriously recommend it. They have some of Frank Hurley's large carbon prints there. I don't know if they were from film or plates (they were pretty sharp/fast so maybe film?) loving incredible. I've never seen a print like that and in the flesh, up close, the resolution was mind blowing. Well worth seeing. Was a really humbling/encouraging exhibition to see.

Is 4.5x6 a decent format? There's a Semi Leotax near here for $55, I believe it's a Semi Leotax DL based on the picture. 16 exposures on a roll of 120 sounds neat but of course your negatives come out smaller. Interesting-looking camera:

There's nothing inherently wrong with 645 cameras, but take in to account you're getting the worst of both worlds between 35mm and MF. On the other hand, folders are nice and compact and there are worse ways to spend $55.

$55 is certainly worth it to get your feet wet in medium format. Shoot black and white so you don't blow C41 money if there's a bunch of light leaks in the bellows or something.

Labs here charge double the price for B&W processing. Are the materials actually cheaper if you develop yourself?

Much cheaper, and the 35mm gear/chems I already have would transfer right over to 120, excepting the enlarger's negative carrier.

oh, my, god. Becky, look at her bitrate.
Black and white is dirt cheap.

I think I've got about 90 dollars of equipment and chemicals and I have enough to process about 150 rolls.

I'm running out of permawash before anything else, I'd have expected it to be the developer first but I've switched to stand development so I'm only using 5mL at a time.

Edit: just realized why, it's because I use the same bottle in both film and paper dev, and unlike fixer I can't re-use it.

Because all C41 gets processed the same way regardless of film speed/emulsion/whatever. Not counting stand processing, which a lab isn't going to do, B&W dev has to be timed differently for every emulsion. They're also probably doing much smaller volumes of B&W with similar fixed costs.

C41 is strap it to a card and bang it in a machine.
B+W means one of the lab staff has to watch a dev tank with a timer for half an hour. Wayyyyy more labor intensive.

6x4.5 is fine, it's the camera that makes the difference. With MF/LF it's all about film flatness and front-standard alignment and rigidity, because small misalignments mean hosed-up corners due to the shallower depth of field. I have a GS645 that's nice and stiff with a meter and a coated Planar, it's fantastic.

A 75/3.5 lens is considered fast for a triplet, so you're in for some soft corners and field curvature when you're wide open. On the other hand once you're down a couple stops you'll do OK. You don't have a rangefinder, so you'll have to guess ranges, which can compound these isssues. I have a non-RF Ikonta with a coated Novar triplet that I like shooting with Ektar as my "holga" because it tends to produce a lot of wonky results. That lens should be similar, but somewhat more flare-y since it's uncoated. Triplet lenses handle flare better than other uncoated lenses because there's fewer surfaces for the light to flare on.

I think that's a good deal assuming it works, I'd say look it over carefully and give it a shot. Wind the lens and make sure it fires - even a novice should be able to hear a noticeable difference between speeds up to 1/125 at a minimum, past that it's just how quick the "snap" happens. The low speeds (below 1/30) tend to stick but you use them less. Take a flashlight and shine it through the bellows while you look for pinholes from behind. If you can talk them into it, take it into a bathroom and it will be easier.
