Just to put some numbers on the resolution of 6x6 medium format. Two examples, the Epson v800 series flatbed or camera scanning with a Sony A7R4. I have done exhaustive testing on this topic. With the 800 series you'll get 2740 dpi, which equates to 42 megapixels. that number represents real optical resolution data that you can transfer out of the film if you tweak the height of the film perfectly in the holders. With the Sony, you use the hi-res composite mode, and in a single capture you can extract 120-ish megapixels of real optical resolution data. I observed a "transfer tax" of approximately 10-15% resolution loss inside the 140 megapixel files. In all cases the digital conversion was the bottleneck - there was more data there but neither methodology could extract it. The 3rd method, a darkroom print, that was the key to extracting the rest of the data. Darkroom printing an 8x8 and then scanning on the flatbed at 3200 dpi generates a gigantic 650 megapixel scan. Inside of that, the real resolution I saw? Approximately 240 megapixels. That was a recent tmax100 6x6 frame from a Hassie. Hopefully that was somewhat interesting, I have been testing the limits of resolution on film with my free time during covid isolation. I may have gone a bit overboard :-) I can also cover the limits of 35 mm, 645, 4x5, etc., with particular details on Adox CMS 20 II when shot with a Sigma 105 mm Art lens - the sharpest 35mm lens and film pair ever made;)
Thanks for the post. The actual resolution of film is very high, but it is hard to get all that resolution into a scan or print. I use an Epson V850, but find that getting the most resolution depends on keeping the film very flat, and the glass panel clean. The flattest film I have ever used is later Rollei 135 or 120 film. You get the best resolution if you use the Epson flatbed wet-mounting the negatives, but that's something I don't think is worth the mess. Getting good scans is some work with both the hardware and software, but if I am scanning things simply to share online, any scanner will do. In regards to wet printing, it is funny to see someone shooting a Leica MP with a $5000 Summilux lens, who then makes prints with a $40 Lucky enlarger lens. As far as digital pixels go, the actual resolution is not the advertised resolution, though that continue to improve.
@@japanvintagecamera8869 Spot on. The lens on the taking camera is almost always the limiting factor. The exception to that rule are some of the modern mid-telephoto lenses, along with the Sigma Art 40mm. That 105mm Art I mentioned will do over 200lp/mm, which out resolves every digital sensor on the market and every film except Adox 20 II. I prefer the traditional scanner process because I get to an end result faster. I find with camera scanning / negative lab pro, the actual scanning part goes quick but the producing a final result part is really painful. For 35 mm though, the Pacific Imaging XAS is my go-to, it is a modern day Pakon with a real-world resolution of 4300dpi / 24mpx for a 35mm frame and whole-roll batch scanning. If I meed any more than the v850 or XAS, I upscale using Gigapixel AI. I do maintain a camera scanning rig, and I do use it when I need the maximum dynamic range, but such instances are few and far between. These days I often shoot XP2 as well so that I never have to clean up dust :-) Cheers and great work on the videos! If you get a chance, check out the 45-90mm zoom for the Brronica. It's quite fun to shoot with.
Thanks for sharing! The Bronica SQ series is a great 6x6 system. I think it’s the sleeper camera. They are cheap but are a bargain in excellent lenses, bodies and accessories. The lenses are sharp!
The SQ replaced the Bronica Classic line of D, S, C, S2A and EC cameras (with cloth focal plane shutter and incompatible lens mount to the SQ) in 6x6 format while the ETRs line ran parallel to the SQ as 6x4.5 format series.
one correction, the SLR has both a prism & a mirror, to undo the upside down and Left to right swaps you need BOTH, the MIRROR does the upside down conversion, as on normal waist level finders (with a mirror) you turn left, but the image on the screen moves right! it is the PRISM that does this final L/R correction!
Two small corrections of note, 1 - Hasselblad cameras are focal plain shutter systems, 2 - the threaded hole on the Bronica SQ that you described as a flash bracket support for an external handle is indeed a mechanical shutter release for long exposures.
How did you manage to remove the lens without the shutter being cocked? It says in the manual that the shutter must be cocked before attempting to remove the lens. I have a SQ, and I can't remove the lens unless the shutter is cocked. BTW, as Clarhett Coalfield has said, the threaded socket on the left side of the camera is for a threaded standard cable release.
I'm a big fan of bronica cameras but unfortunately here in northern europe they tend to sell instantly when they come to market. So finding a good deal is difficult.
is the store still functioning? I bought a camera on it 3 days ago and have yet to receive a shipping confirmation. Will gladly delete this comment after an explanation.

Yes. Into the present millennium. I am lucky enough to have both and love them.

Also the ISO dial isn't just a reminder - it works with the metered prism finders
No, Hasselblads also have a leaf shutter on the lenses, although it's mechanical instead of eletronic.
Love ur videos.
I could never find the cameras in your store after watching the video 😔

Uh, the standard waist level finder doesn't have a built in adjustable diopter.

You should have received an automatic confirmation, I will look into it.
@@japanvintagecamera8869 I got the automated one but I haven't gotten a follow-up for the tracking info
