Hello,

I have already an R10 and the RF 100 400mm (160-640mm eq. with the APS-C crop factor). I'm very satisfied with this combo. But for BIF i'd like a longer focal lenght ...

What do you advise ? (budget: <1500€)

  • (RF 100-400mm f5.6-8) + 1.4 extender (pros: price, zoom range, size&wight, USM / cons: optical quality because extender? 896mm eq.)
  • RF 600mm f11 (pros: optical quality?, 960mm eq / cons: price, fixed aperture and focal lenght, STM)
  • RF 800mm f11 ???
  • other idea ?

Thanks a lot for your responses.

There was a thread a few weeks ago discussing the R7 + RF 100-400 with and without 1.4 extender. In my case I tested this combination and found that IMHO, on the R7 the extender is not worth it as the pictures with the extender had less detail at 560mm F11 vs 400mm F8 without the extender and cropping to the same field of view. It might be due to the higher pixel density of the R7 and diffraction, but I ended up returning the extender.

Regarding the other lens options I have no first hand experience, but if the budget is 1500, crazy thought, maybe upgrading to an R7 with more pixel density?

Thanks a lot for your answer.

My idea was to spend less money on the camera and more on the lenses... maybe i should have bet more on R7 ;-(
