I had no intention of getting RF lenses when I bought my R6. I broke that rule to get the 200-800 but I'm still using all my EF zooms, Sigma 70-200 EX, 24-105 F4, 100-400 Mk1 &2 and see no reason to change until those lenses quit. At 82 I'll pro0bably quit before they do.

I did it on my R3. I don’t think my 1Ds Mk III can update lens firmware.

Yes, the EF lenses still work great unless they can no longer resolve to high MP levels of some cameras (not unique to mirrorless) or keep up to work you're doing (again, not unique to mirrorless).

Yes, RF lenses can be newer, lighter, and use technologies that allow for that, but there has to be a deficiency in the current lens(es) to make the switch. That is, unless you're independently wealthy.


The high MP chase ....sure.

It's like drinking good wine from a very fine crystal glass - almost afraid to break it, thus enjoying the wine tasting moment ...a bit less
The TS-e lenses are no doubt a god example; so are the Otus ( classic) line. Not saying is wrong to switch, but at this point, lighter lenses or more MP is not a must. Give me dynamic range, unlimited just like our eyes, and I will go back to shoot at 2MP

I use my Canon mostly for portrait photography. It’s the only kit for which I don’t mind having a few large and heavy lenses, since I don’t walk much with them.

So, I have the EF 70-200/2.8 and actually got rid of my RF 70-200/4. I also have both the EF and the RF 135mm lenses and I’m leaning toward selling the RF, as I don’t use it enough and I don’t need the modern sharpness.

I also have the Zeiss 21 and 135 lenses in EF mount, that I’ll probably sell. Just don’t use them much.

My smaller lenses are RF versions and I have the RF 50/1.2, because I found it much better than the EF version.

It's difficult to determine at what point which cameras support lens firmware updates. I'm not going back through all the manuals.
If the RF bodies can do it through the adapter that's easy enough.

The problem is that (pathetically) Canon still has no sensor with resolution that is better or as good as the >10 YO 50MP 5DsR. So any lens that was designed with that in mind should be fine on the R5/R5 II.

I only use EF glass, no way I would pay for the new RF versions for what I shoot. And they are very cheap now. Just had a mirrorless Canon for a few days now, but without a doubt it is better AF and way more accurate than the DSLR.

I might look at it the other direction, it's pretty amazing Canon came out 50mp sensor 10 years ago. No one has passed it. Nikon hasn't, still 45mp, Sony only barely has at 60.

I field tested the 61MP a7RIV in late 2019. I did not use it in 2020 due to the viral situation, and then the R5 arrived later that year. But I've used the a7RV (same sensor as the a7RIV) quite a lot and the sensor IQ is better than any 45-50 MP Canon. So it is going on 6 years and several other cameras now have that sensor. I've used adapted EF lenses with excellent results as far as IQ. However, the AF varies by lens and is undesirable for action.

I still have all my EF lenses and use R6/2 as a way more advanced 6D. So far I only bought one RF lens, because it has no equivalent in EF world: RF 800/11.

I will just add my $.02 to "EB's "reply...I went to the Fuji GFX 100sii MF body with 100+ mpx looking for that "magic" huge mpx IQ boost. Yes the files it makes contain mucho info BUT...The menus and the amount of them that influence the resultant file....have me dizzy! ....and very confused! Which at 78 isn't hard to do.

They do not intimidate others but me they do.

Yes it is me..The camera is fine in the hands of a competent photographer....My 5DSR's will keep me for now....I found adapting EF lenses to the GFX was less than ideal...FOR ME!

You can stitch those 2mp files together and make larger ones at least.

! Classic Mike.

No one has passed it.
If a 20% increase (60mp vs 50mp) is 'barely', then just 6% less can be considered equal.
So Sony,Panasonic, Leica, Nikon have all equaled the 5DS.

Alternatively, we could just talk facts and state the A7RIV passed the pixel count of the 5Ds 4 years later.

Sony A1 8640 x 5760
5DS 8688 x 5792

So the A1 has 48x32 pixels less (NOW THAT IS BARELY!) but can do an extra 25 fps.
I suppose you'd call an extra 25 fps a 'few more'?

Quick backstory, I was a longtime Canon shooter, from around 1998 (I'm not old, you're old) until the Sony A7 came out and I jumped to mirrorless. I picked up a "smart" adapter to adapt my Canon lenses while Sony filled in their lens lineup. Fast forward to whatever year it is now, and I'm shooting with native glass and I've got Canon lenses sitting in a cabinet.

In my opinion, adapting to Sony is no longer worth the hassle, but I've been away from Canon so long I don't know if it adapts better to their mirrorless cameras.

The EF lenses are still as good as they ever were — the trick is finding someone who can use them. The simplest solution is to just offload at one of the use-gear resellers, and if you aren’t concerned about how much you’ll get that is a fine option. It might be ideal for you.

As to using the old lenses on newer Canon R cameras with adapters, I have no direct experience to offer — though I will say that in general when I’ve used adapted lenses this way the extra pieces and steps are a bit annoying, especially when native options are available.

(I continue to shoot EF lenses on my 5DsR for now, as it performs pretty well for the photography that I do with that system. I’ll replace it eventually, but so far I haven’t found the option that persuades me to move on.)

From my experience, the donated gear is more likely to find a useful home if you can first make contact with a faculty member who will actually use it with their students and discuss it.

If you just donate to “the school,” it is possible that there actually isn’t a program that can use it or that an existing program might use incompatible gear. (I once thought I was being generous by offering to donate an older, functional large format Epson printer to a community college that I was connected with, so I had a brief discussion with photography faculty… who explained that they really couldn’t use it since they would have to acquire yet another type of ink cartridges.)

…the Sony color science and ergonomics from Hell


Could someone explain this idea to me? I have friends and associates, including some pretty successful and reasonably well-known photographers, who are using Sony equipment to produce photographs every bit as beautiful as those coming from Canon, Nikon, and others. (By this time — decades into the digital photography thing — I’ve heard every brand described this way by those who use another brand… so count me as a skeptic!)

For my purposes the EF 16–35mm f/4 IS is a better lens than its RF successors. Canon still haven’t made an RF successor for the EF 24–70mm f/4 IS. These 2 lenses and the 100–500 form my main lens set for the R3.


Since upgrading to the R system is one of the options I continue to ponder (the other main option being a switch to Sony or, less likely, the Fujifilm GFX system), I’ve decided that one lens I would definitely keep and use wiht an adapter on an R camera is the EF 16-35mm f/4L IS. That is a really great lens and I don’t see anything better than what I’d get from using it with the adapter.

The missing RF 24-70mm f/4 equivalent is a factor (though not the biggest one) that has kept me from moving to the R system.

I’m skeptical about that, given that EF lenses worked very well (and still do) on the 50MP 5DsR, which has higher resolution than any existing Canon R body.

And now I see the following…

Yes. Exactly. pathetically.

Particularly so when they used to be the resolution leader in the FF space and when Sony has been producing 60MP FF sensors for years now. Heck, while Canon only does 45MP on FF, Fujifilm does a pretty nice job with 40MP on APS-C… using Sony-built sensors.

Would moving from 50MP to 60MP make a world of difference? No. Would moving down from 50MP to 45MP make a world of difference? No, again. But the Canon MP stagnation makes a switch to R far less compelling… and allows me to continue using the 50MP 5DsR while I watch what happens with other manufacturers.

This fact is what a) keeps me using my 5DsR and b) has kept me from moving to the R system, and c) has me weighing alternatives from other non-Canon brands. There’s a very good chance that Canon will ultimately lose me as a customer due to this inexplicable oversight.

Canon EF-RF adapters work great and you can even add filtration to wideangles that did not accept filters.
If you are still mainly on single-shot landscapes, it's probably not worth getting a Canon RF body until they have a better sensor supplier.

I bought my R5 4 years ago and still haven’t got an RF lens yet , just haven’t felt I needed to
My most used lenses at the moment are EF 300 2.8 and Sigma 150 macro non OS
Even if I had the budget for what I do at least, I can’t see any reason to upgrade lenses to RF

Hey, if people think 50mp is "pathetic," they must think Nikon is absolutely horrible, since they aren't at 50mp, even 10 years later. Apparently the A7r3 isn't the best landscape camera ever, either, as some on Sony board claim, since it's only 42mp. If they think 60mp is so much better than 50mp, good luck, 20% increase in pixels isn't that much

Sony took 4 years to barely pass the 5DsR, not very impressive. And that sensor is 6 years old, not exactly the latest, either.

These ridiculous discussions over Canon having insufficient resolution only make sense if you dont look at the other brands. And Fuji finally passed Canon's 32mp aps, Nikon and Sony haven't even caught up yet past 26mp aps 6 years later, of course on FM this inexplicably makes Canon a problem. Of course Canon is often inaccurately lambasted on here

What's ridiculous is you saying "No one has passed it", even though you then immediately point out that's untrue.
I couldn't care less about a few megapixels. I just think facts matter.
