Thank you all for your replies! So it looks like the main benefit of getting a Rollei is in the ergonomics/size/weight. I have the 80mm f2.8 and the 135mm f4.5. I love the 80mm but I do find the camera a bit builky, but it is a steal compared to the Rolleiflex's. The prices on these lenses are pennies compared to the Rolleis and Hassy's so I'll keep this camera as a system and aquire some more lenses and maybe a Rolleiflex 3.5, Rolleicord, Yashicmat, Autocord, when I want something lighter and smaller.
Rollei invented the TLR in the '20s, NOTHING beats Zeiss glass (although I do like the look that comes from a Schneider Xenotar). Rolleiflexs are light, versatile, built like tanks, quiet, and I've had no problems with the brightness of the screens. The responses I read up to this point, seem to be only from Mamiya users with either little or no practical experience with a Rolleiflex.
Rollei
cord is a completely different model, less features, sometimes lower quality lenses than the Rollei
flex models, because they were made to be more affordable to the photographer who wanted to get into a Rollei, but were on a tighter budget. That being said, the Rolleicord Vb seems to be their best model overall.
Rolleis are higher priced, because they're worth it, (not down to collector B.S.) and are like money in the bank. They're the Mercedes Maybach of cameras. I've been using Rolleis for over 30 years, and actually prefer my 1945 Tessar model over the 1955 Planar (although each have their own
look and purpose. I can shoot a frame in less than 45 seconds (usually less than 30sec as long as there's no people to ruin the shot). So, speed is no problem, and the
sport finder makes shooting movement(s) a snap.
I've used a mate's C330, and hated just about everything about it. The optics let me down, the weight was a nightmare, as was the system for changing lenses. Now, I'm not completely off Mamiya, I use a M645ProTL as a replacement for 35mm, but the Sekor optics
do require a bit of trial/error to find the proper film to try and get the most out of them. The Maco/Rollei films give me the best results, especially the Ortho25. Simply beautiful results, as well as Rolleipan 200, and 400-S.
Tried the TMY-2 when I received 2 trial rolls from Kodak, and while better than the horribly picky to work with T-Max films, the beauty & tonal range of the Maco films just isn't there.
So there ya go, my 2¢ of advice. Once you shoot Rollei
flex, you'll forget completely the C330, and wonder why it took you so long to switch to the real thing.
