Regrets Going From DSLR to Mirrorless?

He's probably mixing it up with the Canon drop in filter mount adapter EF/RF. That one is indeed 24.5 mm thick. It doesn't give correct focus without the filter inside, which has a slightly corrective effect and puts you "back in focus", so to speak.
This also implies you can't use that adapter emtpy. At least you need the clear glass inside.

By the way, my R-series camera has the same kind of wired remote control connector as my EF-seriers cameras have.

Maybe so.

Interesting... I sent my 300 in for inspection/cleaning, after not being 100% happy with the sharpness, and they reported finding a damaged filter holder. I bet a crooked filter, even a clear one, could have a bad effect. I'll contact them next week and ask about this.

Thanks Tom.

Feeling better now.

Best

I have slot covers so that I can use this without filters as a do-everything adapter but never tested it at infinity.

The difference is so small that if the lens allows some overshoot at infinity, maybe that's enough.
But the general rule is that this particular adapter should be used only with one of the three possible filters inserted, i.e. ND, polarizing or dummy.
But a dummy filter is more expensive than the simplest adapter, so there's no economy in that.

Agreed about the minimal effect at infinity. But always a good idea to know the limitations of every piece of equipment.

I plan to use the drop-in filter version on urban trips and hikes when I've got my EF24-70 and EF16-35. The ND and CPL are handy to have and I bought the slot covers for when I'm not using the filters on Amazon for $15 for a pair of them

But I should test out the Sigma 14mm f/1.8 wide open with the adapter for Milky Way images.

Let us know if it works without the clear dummy filter Canon claims is necessary if you don't have any "working" filter in there.

Considered switching fully to mirrorless but my primary for sports is still my 1DX (not made of money over here) and I use my eos R for a backup just in case. The main thing about mirrorless is the wide-area use of focus points. I can actually focus on someone's eyes during a portrait compared to my DSLR.

Yes, it's obvious that mirrorless has several advantages that a DSLR can't really counter. At least not without doing as the 1DX Mark III, which has some typical features you expect from mirrorless cameras. But then you need to use it in live view, which is an ergonomic disaster.
Being able to record video using the normal viewfinder is another nice mirrorless niche.

The only one I've tried on the R5 that doesn't work well is the 300 L IS mk 1 - this weekend I shall try it on the R3 and see if it works any better. If not its going the same way as the 1Dx3. If it does work then I have to make a hard decision whether to keep it or not anyway.

What is the 300 not doing? I just got an R7 and have a 300 L IS Mk 1 that I haven't tried with it yet. Curious if I'm going to have problems.

I finally made the switch this week to an R7, so I don't have a long history yet but so far I'm getting to be happy. I have most recently (and still have) use a 5D3 and 7D2 together since they were released. I had lots of other stuff from 1D series to xxD series in the past. The thing I love about the 5D3 and 7D2 is they have nearly identical controls and so using them together is brainless to do.

So in my short week of playing with R7, my main two "regrets" if you can call it that are lack of a battery grip (I do a lot of sports that is nearly all portrait mode) and completely unique and different controls. After watching a bunch of video tutorials, I'm now liking the R7 control layout after tailoring it more to my liking, but it is still unique from every other camera. But if I could should a 1D series and xxD series together then frankly nothing could be more different from the 2 of them.

Canceling those regrets are a pile of advantages:
- Fast - 15-30fps... amazing fast
- IPIS - Last night I was taking pictures in low light with my EF 17-40 f/4 L at 1 second shutter speed that were sharp. Not that I'd ever want to really do that, but IBIS opens a whole new area
- EVF - I thought I'd dislike this, and there are some things I don't like, but I'm really shifting to use this to make my settings changes while shooting since I don't have a top LCD for settings changes. Being able to see the exact shot beforehand, with DOF, and histogram... great. At this point I'm shooting with the back LCD not even opened up... I can review my shots in the EVF. I may back off on that at some point, but EVF is mission control now.
- Fv - I usually shoot Av or M with the other bodies. Fv is my new default everything mode and has completely changed the way I prepare a shot. Being able to play with the key 4 exposure factors, seeing the exposed shot ahead of time, with the histogram. And on the fly effectively go in out and of full manual shot by shot.

I plan to sell the 7D2 and then what next I'm not sure. The logical next step would be to swap out the 5D3 for either a 6R2 or 5R. I may pick up a speed booster and just see if that is good enough. I don't bring out 2 bodies much any more and not sure if I will. But I'm happily on the mirrorless journey now, but hybrid for the time being.

The focus speed was very slow and it wouldn't work in H+ (That is not the deal breaker, the slow AF was)

But with the R3, focus speed is acceptable. H+ I think works - or at least can be selected. Yet to really see if it does actually work!

There is a strong correlation between focus speed and battery power when using physically huge lenses with big heavy glass elements to move. . Manufacturers may not acknowledge or admit to this, but it is real. . Hence, I think that is why your R3 provides acceptable focus speed, and I believe that it is the only mirrorless camera that Canon has that will move those elements quickly enough for demanding action photography with a truly large lens.

@convergent you are on a very similar path as I. From Spring '22 I shot with a 7D2, then in November added an R7 and shot with both. Both were great, really. Very different, but both very good. Neither was gripped and I longed for rotated controls.

Agree with your benefits there but haven't messed with Fv. I do have a SpeedBooster.

I did move the 7D2 along to a new home a month or two ago (I miss holding it; it just felt so good!) and I am replacing it with an R3. It's a crazy splurge but it checks all of the boxes. I will have to figure out how to distribute my available lenses (all EF for now) between a FF and a crop. Hopefully the 300 IS will still go full blast on the R3, but if it doesn't then I'll put it on the R7 where I know it does.

I was thinking of buying a mirrorless camera, but some guys adviced me not to. So I live happily sith my 5D MkIV and my 1DX MkII. They are more than sufficient for my use!

Advice based on what? I didn't go mirrorless for a long time because I "Don't like EVF's" - but having had the R5 initially, my fears are unfounded - basically they have got to the point of being fast enough and clear enough to be very usable - and have a lot of advantages, proper level in the viewfinder (Very handy for me having astigmatism and unable to judge level!), histogram, post shot image review without taking eye off the eyepiece. Disadvantages, needs power to see anything, there is a very small delay - but it is really small.

Other than that, they are only better than traditional DSLR's - better AF systems being the major one.

But if your current camera's work for you then that great! Not going to tell anyone what they should or shouldn't do. Never have, never will.
