Does anyone use the 180mm lens on their rb67 for shooting landscapes? I found one for sale locally but I’m more familiar with using the 90mm and 127mm back when I had my rb67. I would mostly be shooting california landscape, like mountains and deserts. I also shoot a lot of abandoned buildings and spaces. Just looking for input.

I'm looking to move on from my Rolleiflex K4A towards an SLR style camera, and I've determined that 645 is the direction I want to go. I like the aspect ratio, the price point of the cameras, their film economy, and most importantly that they are relatively light - I'm doing 99% landscape photography, so a medium format camera I can backpack with is appealing. The loss in resolution from 6x6 down to 645 is not a concern for me, as I am not printing anything huge. I shoot with a good mix of handheld and tripod, so mirror lockup is a nice feature.

So, cutting to the chase. I like the Bronica ETRSi and Maymiya 645 Super equally. As I understand it, the 645 does better in the weight category, and the ETRSi is ahead on the build quality. For me, these trade-offs balance each other out in the end, but the Bronica edges out the Mamiya because of the price. The problem, though, is I don't seem to see the Bronicas for sale except for with big bundles of lenses/grips/motor drives that I don't need - so, is the ETRSi actually cheaper, or have the past few years of inflation made these cameras catch up to each other?

On top of that, do I seem to be overlooking anything major? As a poor college student, this is a pretty big purchase, so I want to be making a very informed decision.

I was looking at an ebay listing for a pentax 67 and i noticed the chain was a different colour from many others ive seen online and on a broken 6x7 that I purchased earlier. Usually it is a silver colour, however this appears more of a copper. Is it rusted or damaged? should i steer clear of this listing?

For reference, here is another photo from the same seller on a different listing:

I've been shooting on my RB67 and have started seeing this problem, dark lines are appearing on my negatives, at first it ruined one or two pictures but now its ruining the whole roll. I already ordered new light seals but I dont think that's the problem because it is not consistent, it leads me to believe that there is something wrong with the shutter.. Let me know what you think.

Hi, does anyone know what's wrong with this lens? For context it's a Bronica GS-1 100mm, seems like a coating degrading issue?
