I recently picked up the 100-500 lens, which has been great on my R6. Been thinking I should pick up an extender, and trying to decide between the 1.4x and 2.0x.
100-500 with extenders becomes:
420-700mm f/8-10 L IS with 1.4x
600-1,000mm f/11-14 L IS with 2.0x
They both overlap.
100-500 with extenders becomes:
140-700mm f/8-10 L IS with 1.4x
200-1,000mm f/11-14 L IS with 2.0x
The lens has to be extended to 300mm before you add the extender. Once you add the extender, you can not retract the lens below the 300mm mark (blocked by extender). This is the one gripe I have against the lens. The range with the extender attached:
1.4x 420 - 700
2x. 600 - 1000
I can tell you this is accurate because I have the RF 1.4x & 100-500. It is also in the Canon RF 1.4x & RF 100-500 material. I do not own the RF 2x and don't plan to purchase. Personally, I don't like the results with 2x extenders other than the EF 200-400 f4 L IS and the Big White Primes. The EF 70-200 F2.8 II/III also does a decent job with 2x extenders.
Just in case you are not aware, the 1.4x TC does not work with the RF 70-200. It has to do with the rear element sitting so close to the mount, doesn't allow the 1.4x extender to be attached.
I was too lazy to find it in the Canon material, but this is from the RF 1.4x TC product page on B&H. Lens compatibility in the description:
- RF 100-500mm f/4.5-7.1L IS USM (can only be used within 300-500mm range)
- RF 600mm f/11 IS STM
- RF 800mm f/11 IS STM
