I've only used a Horseman 6x12 back ... in undergrad.
I'm looking to buy one. There are a few choices.
Sinar, Linhof, Horseman, ShenHao, GuaHua(sp?), etc.
I've pretty much ruled out the Sinar and Linhof backs because they're so freaking expensive --yes, I'm sure they're worth it but student loans only cover so much and I'd like to eat more than every 3 days.
I know and like the Horseman but it's also a little expensive. (I'd buy one in a sec if I could find it for $250)
This leads to the S.H and G.H. backs... The price is right, but I have concerns:
1) film flatness---'nuff said. I was satisfied with the horseman.
2) that stupid red window on the back---last time I used a red window it was on a holga...I had to put tape over it which is completely LAME!!!! Does this window actually block out enough light and what happens if you use color film? Will I have to tape this window too?
3) breakability--I'm hard on equipment. Sometimes I'm on my bike, sometimes I'm in my truck, sometimes I'm traveling down a non-road in Bolivia. I guess I'm afraid of one of these backs opening up. I don't want to have to tape them up like a holga.
Has anyone used these? Can you respond to my concerns? Any horror stories?
