Sony RX10 IV vs Canon 7D mk II & 100-400 IS mk II
4

Here are a few images comparing the quality of the RX10 IV vs Canon 7D with the 100-400 IS mk II, shot at Slimbridge Wetland Centre.

All shots are handheld.  I wasn't taking as much care taking the shots as I could have, so better technique might have produced better results.

Both cameras set to 400 ISO.

Virtually all of the images are at maximum focal length, i.e 600mm on the Sony and 560 mm equivalent on the Canon.

Canon aperture f/5.6, +1/3 EV

Sony aperture f/4, 0 EV

Canon jpg images sharpened 52% with 0.2 pixel.

Sony images jpgs direct from the camera.

The Sony is very sharp but has more noise.

My 100-400 IS seems to back focus sometimes  or just be a bit off.

I was shooting the Canon by mistake in mode 3 image stabilization but soon switched to mode 1 with much better results.

Obviously the birds are not perfectly stable so that will introduce some variation to the images.

I bought the RX10 IV to replace my Panasonic FZ1000 for use when hiking after being very impressed with my wife's RX100 VI.

I have seen some failure to focus on birds in flight but that my be my lack of experience or poor technique.

The focus point on the right hand Canon image was on the eye.  This clearly shows back focus.

Want are your conclusions?

To me the Sony seems to do better than I would have expected! I just spent 10 days shooting side by side with my Sony RX10iv and a companion’s 7D and 100-400. I have not seen her results yet, but I am happy with mine, all things considered.

I'm bound to be prejudiced but the Sony seems to hold its own at 400 ISO. At ISO 100, it might even look a little better (less Noise)
Enjoyed the comparison.

Thanks,

Bert

Never saw it.

Haven't touched my Canon gear since using Sony.

Nice comparison, thanks for sharing these images.  I think the Canon looks a little better across the board, but the RX10iv  certainly holds up very well.  I looked at Canons and Nikons, and went with the Rx10iv instead.  I never did get to compare image quality like this though, so I appreciate seeing your comparisons.  The one I really wonder about is the Nikkor 200-500 on an APS-C compared to the Sony.  How would that do?  I know I am really happy with the light weight and ease of shooting with the Sony, and I probably wouldn't trade that for a much heavier rig.  This Canon comparison is certainly food for thought.  Certainly not enough to make me regret my choice though.

for me the RX10-4 is my go to camera for focus accuracy, speed and sharpness

If I want better IQ however (for producing prints for sale etc) I will now use my Olympus EM-1 mk2 (my canon 7Dmk2 and 5D mk2 went some years ago)

The RX10-4 is probably the most satisfying camera I have used to consistently capture the images I want with my subject range (bugs, bees and butterflies, wildlife and birding and high speed action water sport)

The big advantages of the RX10M4 are that enormous 24-600mm FF equivalent zoom & never having to change lenses as you always have the correct lens on the camera.

When I shot weddings in common with so many other wedding photographers I would have two FF cameras round my neck the first with a 24-70mm F/2.8 & the other with a 70-200mm F/2.8.

I missed you original past as well. Thanks for doing all that work and comparisons. There is a huge amount of work involved in doing that. I wonder how things might have looked, if you hadn't sharpened the Canon images. It seems that by doing that, you remove the level playing field. The other factor is that the two shots in each case aren't identical. That is something it would be impossible to get without some specialised equipment and maybe not even then. I have tried bird comparisons and its nearly impossible to get exactly the same each time and also very frustrating.

I have been out with a Canon 7 mk2 shooter on a couple of occasions, but he uses the Tamron 150-600mm lens. Sometimes we have had near identical shots and mostly mine are sharper. He gets variable results, so I wouldn't want to put too much emphasis on that aspect, as he gets some sharper ones as well. Operator error is always a factor. At least with your comparison, its all done by the same operator. My point here is that the Sony is matching everything he puts out. I will say that this is in reasonable light. The Canon should win in a lower light comparison.

Below is an image I am particularly pleased with in its details. Would the Canon do better? I can't say for sure, but this one looks pretty good to me.

Once again thanks for the big effort in comparing all those shots.

Not quite. I also often carry my a6500 with 10-18 (15-27 equiv lens) alongside either my RX10M3 or RX100M6. For example, here's a few pictures I took on my recent visit to Delphi, site of the Oracle, in Greece, which needed both cameras:

The whole ancient site is on a very steep hillside

.

The theatre (which, amazingly, seated up to 5000)

.

Polygonal dry stone wall with curved joints, to resist earthquakes, under the Temple of Apollo

.

View down to Itea and the Gulf of Corinth

I've just swum against the tide in this respect, in that I've sold off my RX10-iv and bought a FF Nikon Z6 with 300mm F4 and 1.4x teleconverter for long work. Yesterday I carried this rig about all day at our local zoo - it is soooooooo heavy.

I have both the RX10iv and a Nikon D500 and 200-500vr and find image quality to be comparable, sometimes with the edge to the sony in sharpness as long as I work within its limitations, ie; not overcropping.

The main advantage of the Sony is its portability can be quite liberating.

To me your comparison is flawed. Shooting both cameras wide open with the same shutter speed, the R10iv would have been using 200 ISO and  consequently the image quality would have been even better. So you have failed to take advantage of the F4 maximum aperture of the RX10iv as opposed to the F5.6 of the Canon. Never compare like for like ISOs with different sized sensors, the bigger sensor camera will always start with an advantage. Although having said that, the RX10iv still holds up well in your comparisons.

You're right about how heavy the DSLR plus lens rig is, but if it gives you the results you want, then its worth it.

I agree with you, David. Its not like for like and as I mentioned in my post above, he has applied extra sharpening to the Canon images, which also adds an advantage to the Canon results.
