It would be the IS II I'd be after and that is close to 10k, used prices of mint 800 f5.6s are around 6k, so there is a massive difference. The original 600 is not too great with TCs - I have the 500 IS I and I am not huge on the TC combination on that lens, and it is supposed to be sharper than the old 600.Just out of interest why would you go for the 800 rather than 600 + 1.4x TC, the prices are similar?
Ah wow really? Well I got mine for a steal, in fact for the price i could get the new 600 I got the 800 L and a brand new 300 2.8 IS II.Probably not something you want to hear when you've just ordered such a big lens, but the brand new one i had was so bad i had to send it back. Just really soft (by Canon big white standards). I've since tried a 600 IS mk2 and that was sharper than the 800 even with a 1.4tc on.
Probably a bad copy of it, but the new 600 is quite a bit sharper. I hope yours is a good one
Cheers! And yeah it's great. The 600mm is great with the TC, people say it's similar to the 800 in IQ but slower with the TC. I preferred the native 800 myself, i don't see how it could be any sharper, it's that good! Plus it saved me over 4k, lol. I'm not a huge fan of TCs myself, i simply hate the 1.4 on my 500 mk 1, i know it's not anything to judge the mk 2s by, but still.Great shot
Yeh the one i bought was definitely a bad copy. Got a refund for it.
The mk2 500 & 600 are a step up in sharpness again from what i've seen and read though, especially with the use of TC's.
Glad you're happy with yours
