I do strictly landscape work - in December I bought the Canon 1DSMK II and lenses - I now feel the Canon 1DS Mk II and it's lenses do not meet what my needs are.
Will for digital back to go on my Hasselblad 503CW - V series; must be 22MP and above.
Also would trade Canon gear for Hasselblad 50 and 100 I class lenses.
All Canon gear is USA and less than 3 months old. Have the body, 70-200 L, 16-35 L, Canon 580EX Flash, remote, etc. All in as new condition.
