Hi - Anyone with Kenko TC experienc, would you be able to suggest
Which one of these provide better iq and overall better ?
5D mark III w/ 70-300mm L with Kenko 1.4 tc
5d mark III w/ 70-300mm L cropped
40d w/ 70-300mm L (considering the 1.6x crop factor or APSC)
I have all the three except the TC. Wondering if it is worth spending the money on kenko when I have the other two options. I heard mixed reviews abt kenko when mounted on the 70-300
You don't use crop factor when you want reach, you need to go by pixels per duck. 40D is 10MP on APS-C and 5D3 is 8MP equivalent on APS-C, not that different. 70-300L+TC+5D3 def beats 40D+lens for reach, that said AF is a total mess with the kenko on that.
If you want reach a 50D/7D/etc. + 70-300L would do better than any combo you list.
