That part of town is torn up for construction. Glazer's moved into their small lighting/rental/film building while the new main store is being built in all that construction going on. Glazer's has way more stuff than Kenmore. They still have a pretty good film selection, developing chemicals, paper and other stuff.
That's good to know - I didn't live in town when I was originally shooting film - 80s and 90s. And, yeah - my lady and I just roll our eyes every time we go down into (or over aurora) S Lake Union... It looks different every couple weeks.

New to me 1968 SWC:


I'll inject that the 38mm Biogon was/is, SFAIK, the widest lens ever made for 21/4 format. Its 90 degree diagonal coverage is about equivalent to 21/22mm on FF 35mm format. There are major difficulties in designing lenses that cover larger formats, so nothing equivalent to the remarkable 15mm Zeiss Hologon, which has a much wider FOV on 35mm than the 38mm Biogon has on 21/4, was ever produced for roll-film cameras.

You mean widest rectilinear lens? I'm sure you're aware that the larger size negative of the Pentax 67 has a 35mm fisheye. What's a 21/4 format?

Edit

Oh, I see, you mean 2 x 2 square format.

There is also a Zeiss 30mm fisheye made for Hasselblad. The 38/4.5 Biogon is the widest rectilinear though, and also now the Lomo Minigon 38/4.5

And the Pentax 645 has a 35mm lens. Though a smaller projected negative on the same 120 roll of film, I think, unless the image circle is elliptical, it still need to cover the same 6cm image circle as a 6x6 camera.

I just wish I'd left it alone and didn't know exactly where the aforementioned one was now.

I was not aware of either the fish-eye for the 67 nor the 30mm for a 'blad. Of course aside from being very wide, the 38 Biogon had a reputation for outstanding IQ, although IMHO opinion the 15mm Hologon is the really exceptional achievement in lens design, the Voigtlander 12mm notwithstanding.

The 43mm on my Mamiya 7II is about just as wide as that 38mm on a 6x6 and it is also a very sharp lens. So good wide angles on medium format are not that uncommon.

The Zeiss F-Distagon T* 30mm f3.5 fisheye was an incredible work of glass to behold in-person. The images from it were equally as stunning. Unfortunately I don't have any of my former photography life of transparencies converted to digital. Otherwise, I'd get a kick out of sharing some.

The Zeiss Hologon (original 15mm version) has a 110 degree diagonal coverage. The Voigtlander 12mm Heliar has a whopping 121 degree diagonal coverage. Both lenses are rectilinear, not fish-eye. The 6mm Nikkor has a 220 degree coverage, but is a fish-eye (it's still available from Nikon, made to order, price not stated). Any rectilinear medium format lenses that approach the Zeiss or Voigtlander?

Took advantage of KEH's Black Friday sale and finally found a great price for a proper lens to put on the OM-3 . . .



I just bought a non working OM-4T for broken prices. It only needed batteries and unlocking the shutter ring to work! Unfortunately the only lens I have is a 28mm 3.5.
