    You mean the EF 500mm f/4.5 L USM ;). It is an old lens now, and if its AF drive fails, the lens is dead. In fact, my copy still works...

    Absolutely loved this lens!!! I bought it with the EOS R (besides the 24-105mm basically my first chosen L lens) and it was a top notch...

    Should you buy an M6, don't forget to check the shutter , using an UWA. There could be some surprises...One lower seal could be worn. As...

    Unfortunately here in Oz we don't ever see for sale any 2nd hand EF 600mm f/4 mkIII or RF 600mm so the only choice is either buy new or...

    In fact, Nikon made some better lenses in the 1950s, but in Western countries nobody knew that until the famous photographer David...

    100% Interesting. I hadn't looked into crop market at all -- once I went full frame I never looked back. As much as I liked the reach...

    I think from a standard consumer perspective I'd agree, but if we take the R7 it's pro turf in appropriate contexts. I think in that...

    Building on this response from AlanF, it might be handy if you ready the Metabones white paper on speed boosters. It's quite...

    I'm a bit jealous. I was so excited when the 18-50 f2.8 was announced that I pre-ordered it. I rarely do that, preferring to see what...

    I think the value of equivalence is to understand the range of capabilities of a given set of equipment, and the relative compromises...

    Yes. For complex lenses, the entrance pupil may be very different than the front element size. I'm fuzzy on the relationship; this is...

    Someone on YouTube said it. I mean, that's proof, right? :rolleyes:
  • neuroanatomist
    I'm not sure that many people really care about equivalence. I certainly don't take a picture with my R1 then try to set up a completely...

    It does seem like there's something like this going on -- but have you found evidence for it being 30%? I think we're all curious what...

    You bet! Happy to hear you're experiencing the same. I'm over the moon with Sigma lenses on Canon bodies and I am excited for the R7...

    I think if I bought into tele primes at this point I'd switch to RF, but since I have enough nice EF gear as it is I am actually tempted...

    Ahh... GAS. And weight savings! I used to be that way about bicycles. That lens does make my EF 11-24mm feel like the RF 40mm pancake!

    With the understanding and respect that people who shoot both FF and CF cameras care about equivalency, I think many of the people who...

    *IF* this lens has any degree of weather sealing it would solve the lens dilemma I've been struggling with and will be an insta-buy for...

    A Painted Lady found its way to my garden today. R5II + 100-500 + 1.4x extender.

    Yeah, even on in the 10D says, 17 was tight. But the standard "kit" lens 18 was even tighter. And for all the concerns about...

    Canon wants 30% of the sale price as a fee for anyone using the RF mount. Pay or get sued.
  • I
    I somewhat feel the same but 17mm ends up just a little too tight often enough for my video projects that I still kept and use the 15-85...
