1D X Mark II or 7D Mark II for Reach?

This was an important question for me. But let me rephrase it more precisely: given the Canon EF 500mm f/4L IS II USM lens and 1.4x III and 2x III teleconverters, which camera produces more real pixels per object? Empty magnification does not count. The 7D Mark II with the 500 and the 1.4x, or the 1D X Mark II with the 500 and the 2x? (The 7D Mark II + 500 + 2x combination was ruled out since its image quality is not up to my standards.)

You may think that the 7D configuration with its 1120mm effective focal length will beat the 1D configuration with only 1000mm effective focal length. Well, you shouldn’t make a decision based on specifications only! Thus I did a little test, a result of which you can see below.

Air was a bit turbulent, and it impacts telephoto imagery with high resolution sensors, so I made a series of shots with each combination in Kuuvik Capture, and selected the sharpest from each batch for this comparison. Also converted the images to black and white because it’s easier to see the sharpness difference this way. 5DS R shots were the same resolution-wise that the 7D II shots, so only included the ones from the 7D Mark II.

The bottom line is that the 1D X Mark II with the 500mm f/4L II and 2x III produces more usable pixels than the 7D Mark II with the 500 and the 1.4x TC. The 500 with the teleconverter is simply unable to feed the resolution-hungry 7D II (as well as the 5DS R) sensor. This is in line with my experience in real-world images.

I prefer the overall look from the 1D X II (not just the higher effective resolution, but better dynamic range, better colors, less plasticky, etc.) to the 7D II, so it pretty much seals the deal regarding which camera will stay in my bag. And with the ability to autofocus using all AF points with the 2x converter at f/8, the 1D X II + 500 II + 2x III is a killer combination. You may need to renew your gym membership though…

1D X II, 5DS R and 7D II AF Drive Speed Compared

I’m currently waiting for Capture One to support the Canon EOS-1D X Mark II. RAW converter options available at the moment (Canon DPP and Photoshop/Lightroom) do not cut it. Their output is seriously underwhelming compared to Capture One, so I’m trying to avoid to check the camera’s image quality now. That leaves other operational aspects to examine.

My current main camera is the EOS 5DS R – it will definitely remain in this position even with the 1D X Mark II at hand. I highly doubt that the 1D X will be able to challenge its superlative image quality. On the other hand, slow frame rate and especially the small buffer are a headache from time to time.

Swan – 5DS R with the 500/4 IS II and 1.4x III teleconverter

That’s why I had been carrying a 7D Mark II in my bag for the last year and a half. But now the 1D X Mark II casts a shadow on the 7D Mark II’s future…

Today I did a little test to compare the AF drive speed of these three cameras with my Canon EF 500mm f/4L IS II USM – naked lens, as well as with the 1.4x III and 2x III teleconverters.

The measurement was simple: recorded a video of the focus distance scale during a full stroke “infinity to minimum focusing distance to infinity” focus drive operation, and then counted how many frames the operation took.

It took a tad less than 0.8 seconds for the 1D X Mark II to execute this operation regardless of whether a converter was attached or not. What surprised me is that the 5DS R produced the exact same result. I must conclude that stories about the 1D’s more powerful battery in connection with the AF drive speed are marketing bullshit. The 5DS R with a weaker battery can do the same. Even with a teleconverter attached.

The 7D Mark II is a different story, though. The naked lens produced the same 0.8 seconds result, but extenders took their toll. The 1.4x slowed focusing time by some 17%, and with the 2x the full stroke took twice as much time as with the naked lens.

In today’s test the 1D X Mark II scored a win against the 7D Mark II, but the true winner for me is the 5DS R… I expected 7D Mark II level performance from the camera, and being on par with the 1D X just makes me to admire it even more.

The Ballet Has Begun – With a Little Extra

Herons finally arrived and I spent the afternoon with warming up for the season. This year will be radically different from the previous ones because of the rig I use. The issue with photographing herons at this specific location is that they land at varying distances. This usually means frequent teleconverter and body changes, and lots of inadvertently cut wings and feet.

But not this time. The 5DS R has more than enough resolution for cropping if the bird lands further away while I can avoid truncating vital parts with closer landings thanks to the full frame sensor. I’m using the EF 500mm f/4L IS USM with the 1.4x III teleconverter.

Images are also much better from the 5DS R than they were from the 7D Mark II and 5D Mark III used for the last couple of years. Not to mention the ancient 1D Mark II… Frame rate is a bit slow sometimes, but still manageable. The real problem is that emptying the buffer to the card may take a lot of time even with a speedy 1066x Lexar CF. This is one point where I expect the 1D X Mark II to do wonders.

Besides the herons, a bunch of bearded tits were also hanging out in the reeds. They are funny little birds and I really enjoy working with them. So much that I missed quite a few heron landings.

The light was great, so why not take advantage of the situation and the cooperating birds? Heck, I already have a ton of great heron landing images…

While Waiting

I’m waiting for several things to arrive. For egrets, herons, and my 1D X Mark II. And while waiting, I’m sifting through last year’s images. The one below was made with the 7D Mark II and the then new EF 500mm f/4L IS II USM lens (plus the 1.4x III teleconverter).

This is a deadly combination that brought me a bunch of great images during the last twelve months. I’m curious whether the 1D X Mark II will replace the 7D Mark II in my bag. Weight, size, reach, convenience are all factors – not just speed and image quality. I’m really really curious. But don’t worry, I’ll let you know once the 1D X Mark II is in my hands.

Tern Landing

Sometimes Fortuna smiles at you. This image was shot with the very last rays of the setting July Sun illuminating the tern. Even the 7D Mark II’s autofocus was struggling, and I was able to shoot just one frame.

But this one frame turned out to be my favorite from the day. Shutter speed at 1/500s was slow enough to let the bird’s wings go blurred, but luckily its head is tack sharp. A few clouds caused the background water and sky to go muted pastel, while the bird is burning in the setting Sun. No flash, just available light.

Photographing Grebes with the 5DS R

The 5DS R became my main camera the instant I got my hands on it. Honestly, I thought that it will somehow augment either the 7D Mark II or the 5D Mark III as a high-res landscape camera, while one of those will remain my wildlife camera. I was wrong.

The 5DS R has so many seductive qualities that I tend to forget all its shortcomings and difficulties (more on those later).

Colors are bold and thanks to the anti-aliasing cancellation filter it can produce lovely crisp images. Such as the following one.

A moment before diving

It was taken in early morning light with the Canon 500/4 IS II lens and the 1.4x III teleconverter. It’s a moderate crop of about 26 megapixels – still enough for a 40×60 cm print. Yes, you can crop the hell out of these files, and still retain a huge amount of details due to the lack of AA filtering.

Some of my former grebe images are 6-8 megapixels from the 1D Mark II… So its a huge increase in usage flexibility.

Of course those huge files have a few consequences you have to live with. First, the 5DS R feels like a medium format camera. From the sound of the mirror to the time it needs to display an image on the LCD. It feels like you travel a decade back in time… Press the play button and wait… Also I haven’t experienced buffer full issues since the 1D Mark II – but run into that quite a lot even using 1066x Lexar CF cards.

You also need more time to cull a shoot. Fortunately I have an app for that: with Kuuvik Capture 2 I can sift the daily crop of 1500-2000 images pretty quickly. An old friend of mine was sitting besides me last morning and was surprised how fast the app deals with 50 MP files (and this was on a 1.4GHz 11″ MacBook Air I use as a field computer).

The next one is cropped from the sides for the rectangular composition. Same lens and converter combo. I stop down to f/6.3 with this combination, which is a bit below the f/6.7 diffraction limit of the camera. So unlike landscapes, one doesn’t have to deal with the depth of field versus diffraction issues here.

Curious visitor

Surprisingly, I found ISO 800 images a bit sharper than ISO 400 ones, so all of these were made on 800. I’ll have to investigate this further before I can draw serious conclusions. But until then, ISO 800 seems to be perfectly usable with no need for extra noise reduction.

The images in this post are the tranquil ones (the action shots are saved for another post). The 5 fps maximum speed turned out to be usable with a little anticipation of what’s going to happen (which also helps your photographs and in the understanding of the behavior of the species you are photographing). But for fast paced action I still reach for the 7D Mark II.

I tend to like to include a bit of the bird’s habitat in my images (maybe I should call them birdscapes), for which the full frame sensor is a real boon. And I can crop the surroundings away if a tight composition is what I’m after.

Breakfast for the nestlings

AF is superb. The best I’ve ever found on a Canon camera (excluding the 1D X, because of it’s faster focus driving speed). The only thing I miss is the AF mode selection lever of the 7D Mark II. I find myself reaching for the lever and cursing who’s responsible for this omission quite often.

A hot topic is the dynamic range of current Canon sensors. Well, while sometimes I would need more (maybe a handful of times during the last 12 years), what the 5DS R offers usually pretty much enough. Especially that I print my images where I have just 6 or 7 stops, and usually expose my images properly with no need to recover from the shadows. Also I like to utilize clipped highlights and shadows as artistic tools… So I’m not complaining on this front.

Good night!

As you may already think, I really like the 5DS R. It’s not the absolute fastest and the most suitable camera for bird photography, but those limitations are igniting my creativity and are not in the way of image making. It’s an exceptional tool for making the kind of photographs I have in mind.
