Canon and Nikon and Pentax and Sony (Alpha) seem to be having trouble selling off their stocks of DSLRs, particularly APS-C models. Some models are up to 46% off and some have other goodies included.
But it’s not just DSLRs. Fujifilm and Olympus have a lot of stock that is deeply discounted. My bet is that Sony is mopping up the competition with the A7 series. See also mirrorless camera discounts.
Lots of filter deals too, particularly on oddball sizes.
Oh, and the Leica 12% discount program that was May that was August is now extended until October.
