Which lens is best paired with Canon 5Ds for bird photography

[limvo05]

Hello,

Can anyone here give me some advice on which lens is best paired with my Canon 5Ds for bird photography?

I have with me a 70-200 F2.8 II and a 2X Extender Mark III. While it is manageable in terms of sizes, that combination is somewhat heavy to carry for any extended period of time. I was thinking of a CANON EF 400mm F5.6 L USM prime, however, I don't know if 400mm is ideal for birds photography? If I was to pair it with my 2x extender, the aperture would be doubled, rendering the combination useless. Lastly, I would like to keep the budget below $2000.

Thank you,

LV

Thank you. I don't think I'll be rushing out to get the R anytime soon. In fact, I thought I heard there are the R5 and RP. Not sure why so many flavors.

The RP is to the R as the 6D was to the 5D (sort of). The R5 is to the R as the 5D Mk IV is to, say, the 5D Mk II. Get the picture?

I am not sure where either the R or RP might fall in the current DSLR lines.  I think the semi-official word is that the R5 will be reflection of the 5 Series.  There is also talk of an R6 that is supposed to reflect the 6 Series of DSLRs.

Yes, yes they do. A statement doesn't have to be assigned to somebody in particular.  It is a general thought that seems to keep going around.  Particularly by the less informed and experienced folks.
