Canon EOS R5 Unite and Discuss!

I think this is the right path.

If the R5 is as stellar as the marketing shows it to be it will be interesting to see how many R users become disappointed with the R. If so then Canon will have to keep the R5/R6 pricing far above the R price or the R will be dead. And just imagine how many R bodies are on the shelves right now.

Another interesting point will be seeing how well or not well the R5/R6 perform with EF glass only. Of course, everything we are seeing is based on RF glass and that super fast body/lens communication he mentioned. I could see myself buying an R5 but no way could I ever change out all my glass.

I’m actually a little disappointed that they cut the R6 resolution down to just 20mp compared to the R’s 30mp. I get that’s it helps for low light and the R6 packs a lot of other features in, but I am not sure I consider it a good trade off.

I don’t do video, never been a “Must have 2 card slots” fanatic and as good as the R is everywhere else, that really only leaves new AF system to distinguish it for me.


I’ve already jumped on the RF lens train. Luckily I wasn’t too invested with EF L lenses, only a 70-200mm f/2.8L IS II I bought used and a 100-400mm II along with 2x 1.4x extenders that I will need to sell. I have a couple other EF’s I’ll keep (100mm f/2.8L, 11-24mm f/4L) and a Tamron 85mm f/1.8. The rest of my EF lenses were Tamron or Sigma and are already gone.

At this point I have the RF 35mm, 28-70mm f/2L, 24-240mm, and 70-200mm F/2.8L. The RF 100-500mm will round the RF kit out well. Undecided if I will get an RF extender at this point.

Decided to make this a separate post, here is what really has me excited about the R5...

When I sold my 80D and 5D4 to go with the R, it left me somewhat “limited” for reach and fast AF focus. No more 24mp in a 1.6 crop to add reach. I prefer zooms and as much as I would love to pick up a nice 600mm prime, that’s just not going to happen.

I had already put together a MFT kit for a small camera after disappointment with EF-M lens offerings. So to compensate for reach and AF I picked up a Panasonic G9 body and PL 100-400mm lens. G9 has a fantastic focus system and the 100-400mm lens is 200-800mm equivalent on the 20mp MFT body due to the 2x crop factor. Of course that pixel count and sensor size creates noise concerns so low light becomes a problem - always have a trade off!

The 100-400mm PL is much smaller than the EF 100-400mm, but the G9 body is roughly the same size as the EOS R.

So I start playing around and here is where the math comes in...

In 3:2 format, that 20mp MFT sensor is only using 17.6mp with just shy of 300 pixel/mm pitch - the downside of MFT, small pixels=more noise. Resolution at 3:2 is 5185 x 3456

If you crop the the 45mp R5 to an APS-C (1.6x) size, you are at 17.5mp with a pitch of only 228 p/mm. Resolution is just a touch smaller at 5120 x 3415

Now with the RF 100-500mm F/4.5-7.1L lens on and with a 1.6 crop factor you are at *drum roll* 800mm. Add a 1.4x extender and you are looking at almost 1300mm f/10 equiv.

Nearly identical Focal length and resolution as the G9 combo with much larger pixels. Only 1/3 stop smaller aperture of f/7.1 vs f/6.3 on the G9 shouldn’t be an issue given the much better ISO capabilities of the larger pixels.


So in addition to selling off my remaining EF lenses, I am also able to shed another camera and lens along with associated batteries, charger, etc. Helps with the upgrade costs as well as reduces the hassle of switching back and forth between menu systems etc.

Will keep my smaller MFT (GX9) and lenses for a “compact” kit, but back to FF when it is time to put the big lens on to try and catch Mr. Eagle down the road.

Some of us are 'blessed' with not owning any EF glass (I'm coming from M43!), and I'm still buying an EF 70-200/4/IS/L II and adapter instead of the MUCH-MORE-expensive and heavier RF 70-200/2.8.

EDIT, July 19. Have decided to order the RF 100-500/4.5-7.1, so I guess I'll be without a long lens for my R5 for a month or 2.. But at the rate the R5 apparently has been preordered, I may not receive mine until September!

I’ll give you a great deal on a 70-200 f/2.8L IS USM II with adapter if you are interested...

Thx but no thx--too heavy.

The RF 70-200 feels much lighter and is far more compact that the EF. I didn’t carry the EF with me much because of the size. The RF is much easier to fit in the bag. It’s expensive for sure, but the RF glass is phenomenal. The only EF’s I have are the 100-400 with 2x and the 85L. I can’t bring myself to sell that one because it was a 40th bday gift from the wife. I also like to adapt it to my M6m2 to get a fast 135. So I see myself keeping the 85 and 100-400 for some time since I can adapt them both to either system for unique purposes.

Im heavily invested in L lens..... Look at my gear list. Adapter for me

Only R glass I want is the 24-105

My L lens are so sharp. I think they will only work better on the mirrorless

Well the nice thing is the L glass works better on the R if anything. The RF glass is faster, but the L glass is as good or better on the R than on any DSLR.

It even detects butt holes.

OMG that is hilarious!! You guys gotta see that. In Canon's defense the butt hole can be mistaken lol

For sure it could. It was pretty funny. Do the algorithms account for a one eyed dog?

Doesn't make sense to me.

$3899 in the US equals about $5600 AU + GST so still about $400 more

Georges and Digi Direct have them for pre-order $6585.

Anyone in the states want to send me one ??

Digital Camera Warehouse has them for $6,800 AUD. I used to buy all my gear from Digi Direct .

Here in Australia it will cost AUS 7000, too much I think.

That’s the Canon RRP, there are cheaper.

I used to find the best deal but from now I’m buying locally from a mom and pop camera store. No commission sales, no pressure. They look after everything. They ship to Canon service, etc.
