Upload & Sell: Off
Just a little suggestion here, considering you want to be cautious with your money, you may not want to buy the "champagne" of 6x6 systems right off the bat.
Why don't you look into the Bronica SQ series? The cost is a fraction (seriously) of a Hasselblad system, but it's enough for you to learn if you'd like to go further down the road with a Hasselblad, or if you'd rather go 645, or 6x7. Despite the ridiculous name (Zenzanon), Bronica's lenses are exceptional - Tamron bought the company for a reason - and were once a mainstay of the wedding/event crowd. The body/back/80mm/WLF used to sell at B&H 10 years ago for $2500. You can find them on eBay or KEH for less than $500.
Or you can buy some Hasselblad stuff, get frustrated, and then sell to me at an enormous discount. You know, whatever.
yeah, i can price out a bronica SQ system on KEH for like $600 with a 50mm lens
maybe i'll go down that road. aside from the body, lens and back, are there any other things i need to purchase to get rolling with this?
