In the video, most of the time the shutter speed was well below 1/1000. My normal walking around shutter speed is 1/3200 but then I am used to a D-500/500pf.

Would you be willing to share the Raw files of that falcon sequence?


Sure see below

RF Falcon Sequence R7/RF100-400

There are two sequences to choose from - see bottom for thumbnails or here for #2
https://duncangroenewald.com/pages/galleryView.html?dataFile=blogs/blog-2022-06-30.json


Bear in mind my shutter speed was too slow for real tack sharp images and bird was side/backlit - nevertheless should give a good idea of the performance you can expect.


Sequence 1 Range: 4734 - 4858

Sequence 2 Range: 4993 - 5058

Use the following URL to download the files, substituting the XXXX with a number from the range above.

'https://duncangroenewald.com/files/raw-samples/R7-Falcon-Sequence/DG7_20220628_1_XXXX.CR3'

E.g.

Sequence 2







Let me know if you have any trouble.

Some more samples with the R7/100-400. Interested in what others think but this is a wicked sharp for the price.

The autofocus absolutely nails it on these birds eyes. Not sure I have found one that has missed yet.

I had the A1/100-400GM at the same but I am reluctant to show those images !! Theyíre not 4 times as good and I think the higher resolution of the R7 might have an edge in the good light!!!

What is it with Canonís white - itís like chalk and tough to recover the highlights - probably DPP - could Canon make DPP any slower if the tried ?

All shot with mechanical shutter and other than the shutter blackout the lag didnít seem to be too bad as I could track these guys for pretty much all the way.

The R7 nails the little birds eyes on the beach and the A1 was unable to - kept focussing on the shells in the foreground ! To be fair it was a different bird and in more the shadows.

Thanks....so far I've just downloaded the falcon launching sequence from the beginning up to file 4825. Takes a while with all the copy and pasting and changing file numbers

I would only consider a single shot out of that sequence to be in focus once it launches and that would be file 4808 and even that is a bit of a stretch for my definition of sharp. A number of the perched on the ground are tack sharp but still the focus is continuously pulsing to the background. But that wasn't any easy focus situation, harsh light, distracting background and foreground. But still.

In the latest batch you can see some images out of focus, and these are easy targets for the AF and the lens has enough dof to play for the AF. But, still, thanks for your consistent work!

So I noticed a focus "issue" with mine a little bit yesterday and rather often this morning. My R7 would lock on and track the eye no problem with birds walking on the ground. But the focus would shift behind the bird to the background and would stay there for 1-2 seconds before shifting back to the bird. It did this quite a bit while holding the shutter half pressed, even though the blue box never came off the eye. It did it with some killdeer yesterday morning and seagulls this morning.... it also struggled a decent bit acquiring focus on my sillouette shots. I don't have my R5 to compare it in the exact same situation but I don't remember it giving me near as much trouble on the sillouettes.

I've had similar experience. This *seems* to be more frequently when the birds are smaller in the frame and there is a bit of a busy background, but that's just a very early impression as I have not spent an exceedingly large amount of time shooting this camera. I don't feel this is something I would have seen with the R3 or the R5.

I probably didn't help matters that I was on/off trying to guess when it would take off. In general it was pretty reliable once it has locked on to the eye but it does occasionally tend to drift off to the background sometimes. And under real stress I would expect it to struggle to keep up.

At this stage my a6400 is looking like a "has been" but my A1 is still drinking margaritas on the beach!

As an entry level camera with all those AF features and customisability it is brilliant - hopefully many more people become interested in caring about nature rather than destroying it!

It is a lot of fun to use and some of the images seem to stack up rather well against those from the A1. Download and compare zoomed in with the birds the same size. R7 details hold up well.

There are 3 A1 images because I was trying to find a sharper one but that's as good as they are and 1/4000s vs 1/2000s on the R7.

A few more falcons - late afternoon sun so challenging light for BIF. All the R7 images are straight from DPP - no Denoise processing. I find Topaz does more damage than good on many of the R7 images.

Here is a link to a page that has more A1 and R7 files and download links for the RAW files from both the A1 and R7. The R7 images look pretty good to me.

Canon R7c ... c for cinema ... so no joy for the stills photographer.

To get a better idea of the differences, take a look at the R5 vs R5c:

Looks real good to me as well. Especially when you consider you're putting a $2100 Canon combo up against a $9000 Sony combo.
I'd take the Canon combo and use the extra $6900 to go on a nice 2 week long trip to Alaska or maybe purchase a mint used EF 400 2.8 II.

But I am a Canon Fanboy so I've been told, so...

Thanks for this! I am impressed, especially when you think that the R7 + RF 100-400 cost only $2,100 .... compared to the A1 + 100-400 costing $9,000.

Let's take a closer look at the shot with high-end A1 with a 50MP FF sensor vs the low-end R7 with a 32MP APS-C sensor ... cropped approx 100%. Exposure for both dialed back by half a stop and sharpened in Luminar 4. The A1 image focus may be a tad off (or maybe it's due to camera shake!) as the image does not appear to have as much detail and sharpness. I cannot believe nor accept that the $2,100 kit is better than the $9,000 kit! Heck, my $2,900 RF 100-500L had better be better than the $600 RF 100-400.

The TDP comparison of the RF 100-400 on R5 vs the Canon 100-400 II or Sigma 100-400 C on 5DSR doesn't look very good. Yet your images look pretty sharp. The RF is very attractively light but I'm concerned about image sharpness. Both my Sigma C and Canon II work really well on the R7 so how much IQ would I sacrifice to save the weight?

I just checked TDP - I agree that the RF 100-400 pales in comparison to the 100-400 II and the 100-500 RF lens (both on par with one another). On the other hand, it seems to be fairly close to the older Canon 100-400 IS L, though the comparison is hard to make due to the significant difference in camera resolution used in the tests.

It's a good example of price vs. performance IMHO. Lower cost, lighter weight, not quite as sharp. But TDP tests are pretty-much pixel peeping too. I can see the 100-400 RF on the 7 as a walkabout combo, a birding hike lens for when you're wanting to travel light.

Thanks! I've been using the 70-300 II as my hiking lens with my 90D. It too tests better than the RF. The extra 100 mm would be nice and it would save just over 1/4 lb not using an adapter. So a close call. Think I'll save the money for now.

You can't crop that much and expect anything to look decent - that pelican was a bit far.

Here is a 1:1 comparison of the swan images







The R7 handily beats the A1 image imo. But then it is 33mp compared to the cropped A1 of 20mp so one would expect it to.

Of course I could have filled the A1 frame by using the 200-600 f/6.3 and then the opposite would have been true!! There would be nothing you could do to match that with the R7 since the frame is already filled.

Most lenses are very sharp these days - I think the last recent lens with soft edges was the Nikon 200-500. The big $$$ differences is in the maximum f-stop - much bigger glass and much more expensive to manufacture - but very little advantage in good light.

Similarly the sensor performance at a pixel level is much the same across all cameras - even cheaper ones. The $$$ comes in the readout speed, size, FPS, heat dissipation etc. Again offers no real advantage when none of these features are required to capture the image.

The problem with the R7 images (and all aps-c images imo) is that there is no room for cropping - its like trying to crop a full frame image twice - the noise and detail will be terrible.
