p.3 #1 · RF-L or FE-GM (No Trolls, Gatekeepers, or Dismissive Responses)


I currently shoot with both Canon and Sony systems.

If Ii wanted just one system for travel and landscape shooting, it would be the Canon R5 or R5 II along with the RF 14-35mm f4L, 24-105mm f4L, and the RF 100-500mm f4.5-6.3L, or alternatively I could probably live with just the 14-35 f4L and the RF 70-200mm f4L. None of the other camera makers have lenses in those specific focal lengths and f-stops that are optically better; if you want faster lenses you end up with much bigger and heavier glass. I say that as someone who is currently leaning towards keeping just my Sony gear, but only because Sony has more versatile options for wildlife photography (at the cost of slightly worse AF performance in some situations).

No offence meant, but the OP's current lens list is mostly in the middle or lower end of the quality spectrum as far as Canon and Sony glass goes; I've owned most of them and quickly got rid of them, but they are probably adequate quality if one sticks to low-resolution cameras. If you want to benefit from L-series or GM glass, you really ought to be looking at a better camera body as well, or you might not see much benefit from your new lens investments.

Ultimately, the trade-off between size/weight and optical quality is a person decision only you can decide how much image quality you're willing to sacrifice to save a few grams of weight.

Time to get out of photography when that kind of minutia keeps you awake at night and causes you to ask others for advice.

We have and deploy them all at work. Here's what I saw in testing...

Wide: (15-35/2.8L v. 16-35/2.8GM II)

Both are excellent lenses, but the Canon maintains better overall resolution throughout its range. The Canon really only has one downfall, at that would be the over four stops of vignetting at the widest setting that does not go away quickly as you stop down. The Sony's better there by a little over a stop but isn't quite as wide.

Normal: (24-70/2.8L v. 24-70/2.8GM II)

Here, they run more equal in errors (no large difference in vignetting or distortion) and CA correction is weak on the wide end for both. The Sony barely does better than their own 24/2.8G and the Canon's outpaced by their older (and, admittedly, large with an adapter) EF 24/2.8 IS, and both lose some significant oomph at the long end. Still, for zooms, either is better than what came before. The Sony wins on resolution and consistency throughout its range, and the difference is significant. Canon does much better with the 28-70/2L, but the Sony 28-70/2GM is more impressive, though the gap isn't as large there.

Tele: (70-200/2.8L Z v. 70-200/2.8GM II)

There are nitpicking little differences (you can get the Canon in black), but, from a performance perspective, they may as well be the same lens. I'd go with the Sony because their 1.4x tests a smidge better with the GM than Canon's does with the L, but I'd be perfectly happy shooting either.

I hope that helps.

Thank you!!! Large amounts of vignetting is a deal breaker for me, so this is really great info to know! What camera bodies were you using?

Anytime. R5 and R3 on the 15-35, R5II and R3 on the other two, a1II and a9II for the 16-35GM II, and a1 and a9II for the other two, though I did go back and test them all with the a9III when we got it.

@snegron7 purely based on what you shared: build yourself an R-system, i.e. find a Canon body with the AF performance and IQ that you like. Sell some/all of your Sony and Olympus gear if you have to.

I am primarily a Sony user, but my advice is based on your comment regarding ergonomics. IMO it is the most important thing. One cannot enjoy photography long-term if he loses that internal comforting warmth coming from picking up and holding their camera. Shapes, materials, haptics, control placement, shutter sound.

If they love a camera, people can be very creative and find workarounds for weak or missing features. Leica and Fuji users know what I'm talking about. But I don't remember hearing or reading about someone who learned to love the ergonomics of a camera which they initially disliked. The nagging feeling will never go away.

Thank you! I agree with you regarding the relationship bewteen how a camera feels and much one enjoys capturing creative images with it.

For several decades I was a diehard Nikon fan. It seemed almost like with every new model, they created a more ergonomically perfect camera (F3HP with MD4 motor drive, F100, F5, D200, D750). When I owned my ladt Nikon dslr (D750), I decided to buy a Canon 6dmk2 just for fun because it was on sale. I was blown away at how amazing it felt in my hands! It's like Canon custom designed that camera specifically for me! The R6 felt the same, but my R6II had that great Canon "feel" plus it performed better than my R6.

Unfortunately, despite that great Canon "feel", the R6II is also heavier (at least it feels heavier to me). Maybe the weight displacement might be more tolerable to me if I had L series primes instead of L series "trinity" zooms? I don't know. I will definitely explore that option by renting a few L primes and zooms to see if I should go in that direction.

Regarding Sony, I don't know if my A7iv is the same as higher end models regarding ergonomics. If so, then that narrows down my choice to go with Canon. However, if higher end Sony bodies feel and perform better (I'm sure they perform better) than my A7iv, then I need to explore Sony options a bit more. Again, I'll probably rent a higher end Sony body to see if I can feel the difference.

In the rangefinder world, equipment is small but quality is big. In the mirrorless world, the higher the quality, the bigger the equipment.

While I would like to get the "trinity" lenses for either Canon or Sony, I'm at odds with carrying a large "trinity" lens attached to a camera

You're going in several different directions at once. I don't think you'll notice any significant improvements in build quality going up to flagship level camera bodies. The R6 and a7IV are both quite solid. Perhaps you need to just try the top tier stuff to find out if it really is worth the investment. As others already suggested, renting would make sense if you devote enough time during the rental period to perform all your necessary tests.

Spend a week with a Sony a1 II and the GM lenses you want. Then do the same with Canon. Consider which Canon body you really need. The R5 II is going to give you hi-res images but only the R3 and R1 are comparable to Sony a1/a9 level speed. Canon makes you choose resolution or speed. Sony puts both in one camera.

Juggling multiple camera systems can be be exhausting. I think you just need to choose one and commit your time and resources to one platform. MFT could satisfy your needs if you went all-in with the OM-1 II and some of the "PRO" lenses.

My biggest issue with both the Sony 16-35 GM II and the 24-70mm f2.8 GM II is significant sample variation - I've had fairly mediocre copies of each of these lenses. Canon seems to be a little more consistent in this regard.

I've read about the vignetting with the RF 15-35mm f2.8 in reviews, but have never actually seen it in any of my photos - probably because lens corrections in Lightroom seem to reduce it enough to not be noticeable.

At the risk of being the condescending troll my advice would be to slow down and really think about what you enjoy about photography, end to end all the way to display, then start ranking/prioritizing. Even as you acknowledge so friction your still at odds with yourself. Leica system is small and excellent but you want the trinity on mirrorless. I don’t think Leica has the trinity zooms. And you can get compact and excellent in all mirrorless systems (maybe not all the way to f/1.4 fast) but then you probably aren’t chasing speed with trinity zooms. And a Leica system when you don’t like the R6 because the Sony focuses faster (if I understood you).

And candidly I get it, no one is making bodies I like anymore and there is t much exotic g coming on the lens front these days (for me). And I also prefer small and light. But it’ll be a merry go round till you define what’s most important and why. And sounds like you’re stuck in multiple systems, unicorns are rare.

Interesting. We've had the two sample copies we use for evaluation, then the eight copies of each we keep in stock and I haven't noticed a significant difference at all between them so far as sample variation. Sounds like one of us is having better luck than the other.

I am surprised you've never seen it. Even leaving corrections on in LR will only cut it in half without further editing.

You are not a troll. I totally get what you are saying, and I agree; I need to take a deep introspective look at what it is that I want to achieve regarding photography at this stage in my life.

This is the thing; when I purchased my very first 35mm film camera back in 1979 (a Pentax K1000), I was hooked! Since then I've had an on again/off again relationship with photography. I have been trying to recreate/relive that wonderful, happy time I had when I first started this journey. Chasing the dragon so to speak. Back then both the gear AND the results I got with the gear brought me joy. Now it's either one or the other. Interestingly enough, I haven't printed anything in years except for the sporadic rolls of film I shoot whenever I buy a nice old 35mm film camera.

So, I've found a somewhat "happy medium"; travel photography. I get that "newness thrill" whenever I travel to someplace new, and I try to capture it as faithfully as possible (including darkly lit interiors of European cathedrals, cobblestone streets at dusk, etc). Walking around those places with a giant camera around my neck sucks the joy out of being there. Yes, I really love to carry my tiny, lightweight OM-5 with me, but the images are something between APS-C and a cellphone. Definitely not anything I can crop, print, or view the tiny details that I couldn't see when I was there in person taking the picture.

I also enjoy shooting the occasional macro images of spiders in my yard and somewhat cool looking birds in my neighborhood. But if I had to choose which genre of photography brings me the most joy right now, it would be travel photography.

One of my future plans is to use some of my images to create oil/acrylic paintings. For that I need to be able to crop certain parts of the images I capture. Smaller sensor cameras won't be of much help with that, so I need to stick with FF cameras.

So, based on everything I mentioned above, a Leica rangefinder with 3 fast primes would probably be the ideal outfit for me. But, like I mentioned in my OP, I don't have Leica money. I can come up with $10,000 for a couple of lenses over the next year, but I can't come up with $30,000 to get my "ideal Leica outfit". Fast "trinity" zooms are economically practical because they replace 3 lenses, but they are too heavy to carry around my neck. Fast GM/L primes are a bit lighter, but I really don't know by how much. So, that's a summary of my "dilemma".

"But, like I mentioned in my OP, I don't have Leica money."

I think you do. You may well have double Leica money in the gear you have.
You could sell 2 of your 3 systems to pay for:

p.2 #10
Have you been on the buy and sell board?
35 Lux ASPH v1 — $2,500
50 Lux ASPH — $2,300
M11 — $5,500

In 3-4 years time, it will all be worth, about, the same!

"I really don't love my A7iv (uncomfortable ergonomics and the fact that I have to shoot 100% manual for every single situation because it doesn't work as efficiently in Aperture Priority + Auto ISO as my R6II does"

I'm curious, what's so special about the Canon that it works better in that scenario? I don't own the A7 IV, but I started on the Sony A7R III, and auto ISO seemed to work fine for me. In low-light situations, I feel that Manual + auto ISO is preferable anyway.

Now for a compact, high-quality system, Fuji APS-C cameras seem quite nice for that. If you can barely bear the size and weight of a FF system but still want it anyway, I think Sony is the better system compared to Canon and Nikon for the versatility of lenses available and the weight of their bodies and lenses.

I've looked at the Sony A7C series myself for their compactness, but I like to shoot with the EVF, and it frankly sucks on these cameras. I used to think that the A7R III EVF was good, but after using the A1, it just does not cut it anymore. For you, I think the A7R VI looks like it's the best camera: good ergonomics and the high resolution you're after. And enough flexibility to use a zoom or a small prime.

Speaking of ergonomics, people are often vague when they hit that subject. Are they talking about how the camera feels in their hands, how they operate, or both? In any case, we are all different, which means you will have to try for yourself and not trust strangers on the internet...

In your OP, you listed types of responses you do not want.

So when I now point out you are posting quite illogical thoughts, please have a think about it before responding in anger.

"Fast GM/L primes are a bit lighter, but I really don't know by how much."

Two Google searches give you the answer:
Weights in Oz/Grams.
FE 24-70mm F2.8 GM II 24.5 (695)
RF 24-70mm F2.8 L IS USM 31.8 (900)
RF 15-35mm F2.8 L IS USM 29.7 (840)
FE 16-35mm F2.8 GM II Lens 19.3 (547)

The simple Google is: Sony 24-70 TDP.
It will take you to The Digital Picture, list the weight of the Sony 24-70 GM and GMII and the Canon equivalent.

I, respectfully, suggest wondering about the weight of lenses is illogical if you have access to Google.
