Hi guys,

First off, I'm a new Canon user, having got the R5 about a month ago. I'm coming from the Fuji ecosystem.

I originally bought into Fuji for travel photography, but over the years became predominantly interested in wildlife photography. I had been using their 200mm f2 lens with the 1.4x TC as my primary wildlife lens. At an equivalent 400mm f/2.8 I found it adequate for most of my photography.

It's not 400 mm f/2.8 equivalent, it's 420 mm f/4.2, factoring in both the 1.5x crop factor and the 1.4x TC. The difference will be important if you're comparing with a potential full frame lens for the R5. So an EF 500 mm f/4 gives you 19% more reach and a very small increase in aperture - nice to have, but not night and day.

But you said you found the Fuji lens adequate for most of your photography, so the 500 would certainly do the job too. It also performs superbly with the EF 1.4x III to give you a very nice 700 mm f/5.6.

I left Fuji because I had always been a little disappointed in their AF performance, which compared now to the R5, is like comparing a bottle rocket to the SpaceX rockets.

Now that I'm over at Canon, I'm currently using the RF 100-500 lens, which is very nice, but I really miss having that fast prime experience and performance. I would very much like to get a Canon super tele in my kit.

The extra reach of the big prime with a 1.4x can be irreplaceable, but the featherweight combination of the R5 and 100-500 is superb. I have a 600, but I will often use the 100-500.


My questions is this; if I buy a used EF super tele now, do you see the the resale value tanking once Canon releases the newer RF versions? I'd really like to get back to the supertele experience as soon as possible and as it could still be a few years before the RF's are released I'm thinking about looking for a used 500mm mk II to hold me over until then. Would love to hear your thoughts! Thanks in advance!

The RF big whites will come in at very high prices, and the EF lenses perform brilliantly on the RF mount so I'm pretty sure there will still be a good level of demand for them. Prices may drop a little I guess, but I don't see them tanking.
