2013 iMac. Whatever the larger size screen is. Upgraded processor, video card, and ram.
I don't plan on spending the extra for a body with just a tad more features. I considered it an option, but I would prefer spending that money on lenses.why not the 70D?
Canon 2.0x III extender to make my 300 f/2.8 IS II a 600 f/5.6 for wildlife shots.
Good luck. The 2x maintains the stellar image quality of both the Mk II and original 300 IS lens, but you need good light for AF tracking. 300 2.8 IS + 2x TC used to be my "travel combo" until the awful light in the UK ruined that idea. Even here in Australia, it's less than ideal, and I use a 1 series body as well. Now I take my 500 f/4 instead, and the 300 gets left at home.
Soon, very very soon.
