I wouldn't say I'm unsure on format, I would prefer 6x7 over anything else I'm just not too bothered about 6x6 if I need to go down that route instead, and I might end up getting a TLR anyway, by all accounts they fun to use, small, light and take great images, so I see nothing wrong with them! Having one would always be useful if I wanted a small and light medium format camera to carry around for a day. I'll be looking through all the TLR suggestions I've been given.
If the better and newer Hasselblad lenses are that expensive I'm pretty sure that would far too much for me. And while there is always something nice about owning a product from a renowned and well recognised company like Hasselblad I'm much more interested in the images I get. If the Mamiya can take great images (especially with 6x7 format) I'd love to get one. Looking on eBay the Hasselblad systems always seem overpriced, I imagine due the continued demand for those cameras, and like some people said the brand, almost reminds me of Apple!
I recently found a Mamiya RZ67 Pro II system for sale for £400, is that the kind of price you'd expect for a system in good condition? Also, which version lenses should I be trying to get if I got the Mamiya? I'd like a standard, wide angle and short telephoto eventually, I'm just trying to get an idea of the overall cost of a basic setup with a couple of lenses.
Thanks again!
