What is your favorite lens? I'm interested in knowing.

Canon 100-400 L


It does everything from making me invisable to the subjects scared of me .... totaking me to the moon.


Its stealth and it does all of the leg workfor me.


I'm from Texas and the only thing better is bigger.


I wish I could afford a 1Ds MKIII so I could use a 2x with auto focus.

Do you use the 1.4x with it? If so how is the focusing and performance? I love my 100-400. I use it on a 40D for surf pics and need some more reach. I' cropping away about 4-5MP of my 10MP image right now.

I dont have either one, Keith


I shoot surfing also .... but cant justify buying a 1.4 or 2x because all of the sports I shoot are fast in nature.


If I understand correctly, the 1.4 & the 2x dont work in auto focus on my 5DMKII or my 7D.


The only use I can see right now for a manual focus multiplier is shooting the moon. I'm thinking rental next time Hale Bop comes around.[]

Thanks Bomb


I have 5DmkII but I don't use that for surf shots due slow frame rate. The 40D's 6.5 fps is good but I'm seriously thinking about the 7D for 8fps and the crop ability of 18MPs. I'd love a 1D4 but I can't justify that.

I hope nobody gets all technical on me, but I would think that the 7D's crop ability of 18MPs would give you similar reach to a 40D with a 1.4x teleconverter -- not to mention the vast difference you'd see in AF performance and image quality (both from better AF and sensor performance in the 7D and from not using a TC). Yes?


With respect to the OP's question, upgrading your body could very well give you a whole new set of reasons to support your choice of "favorite lens" -- or it could give you new-found appreciation for glass you don't use that much.

Yeah that is why I was asking. I didn't realize the limitations of converters. 7D is the route I'll take.
