Canon 5Ds DxOMark Figures Are Out

Surprise, surprise, dynamic range again falls short of what cameras with Sony sensors achieve. Thom Hogan says this does not matter, although I disagree. If the sky is included in the picture, it will often burn out that bit sooner on a Canon model. Admittedly post capture processing on a Raw file can recover a lot, but I would be happier if there was more information captured in the first instance.

It's swings and roundabouts. I found that the overall latitude for processing RAW files from the sony cameras was about the same as canon, while the DR was noticeably better it had limitations in other aras (particularly noise handling)

The A7RII looks very interesting and I'm hoping to check it out soon. But overall, I'd rather have higher ISO capability to get a clean shot than have greater dynamic range with noise that looks like mush. Maybe taking the comparisons to extreme but we're not far off splitting hair territory.

The exact performance differences aren't what interest me the most though, it's the fact that sony are now in the ballpark territory with their cameras... and innovating faster. This is great for photography, capabilities are increasing all the time, but it's bad for Sony because every time you buy kit it's outdated less than a year later by Sony themselves!

Canon need to sort their act out on sensors to retain their number 1 position.

I'm using the 5DS and 5DSR next week, really looking forward to it.

As with anything, sensor performance is a compromise between competing requirements and I suspect that Canon is making some different choices compared to Sony. That said, the cameras I use which have Sony sensors seem to yield slightly better images overall than the admittedly older Canon model which I own. That is the original 7D and while I can see some improvement in image quality coming from the 7DII, which you would expect after five years, most of the new camera's upgrades were elsewhere. The AF and video chiefly, although the latter holds no interest for me.

The reports I have heard of the 5Ds models is that Canon has skewed performance towards the lower ISOs and that noise makes an appearance at lower levels than we have become used to of late. This suggests that Canon has pushed its sensor technology as far as it can so far as resolution is concerned, but has made a sensible choice in respect of ISO given the likely uses to which most people will put these cameras. I am certainly looking forward to see what you make of it.

I am still in a position where I cannot see an obvious successor to Canon and Nikon, which could include products from those companies themselves, of course. Right now, Sony seems to be making the biggest strides with the A7IIR looking to be its most mature product to date, addressing previous issues such as AF speed and the menu's shortcomings. Given Sony's track record, though, I would prefer to wait another year or two to see how things pan out. Just how committed is it really to the A7 system? For different reasons Olympus and Fuji do not quite do it for me, either, and Samsung does not appear to be a serious player. It looks as though I shall be muddling along with a mixture of mainly inexpensive cameras for a while longer.
