User3997598970: I found the least “smart” phone I could find to use as a phone. For pictures I use a Canon 7D and mostly L straight lenses.

@Micheal Long: Now that all depends on your pockets ;)

Madaboutpix: A simple thanks for including Ricoh/Pentax in your interviews, DPReview.

Reading some of the comments, I can't help wondering about the source of all that bashing of, impatience with, and whining about all things Pentax. As far as I am concerned, as someone who has been happily shooting Pentax DSLRs and lenses for nine years now, I see nothing in the interview that would discourage me from going on to do so.

Yes, Ricoh Imaging remains a niche player, which means they cannot and will not roll out a stream of built-in obsolenscence product at breakneck speed, but they seem to have a strategy and some nice stuff coming and more under development.

There is a remedy for the negativity out there: grabbing your existing Pentax and Ricoh gear and creating the stunning photography that it will deliver in capable hands any day.

"Reading some of the comments, I can't help wondering about the source of all that bashing of, impatience with, and whining about all things"

You must be new around here? That's what happens to every post here ;) I removed the spurious bit about Pentax, as it's not a manufacturer specific response.

In reply to:

entoman: The most important thing to note here is that you have a choice. The M50 (and presumably all future Canon cameras) gives you the choice between enabling compressed CR3, or default uncompressed CR2 files.

I would imagine that after a few iterations, the CR3 option, if it proves popular, will become the default setting, but that we'll still be able to opt for CR2 if we wish. Also it's almost guaranteed that if you have a (future) Canon with twin card slots, that you'll be able to save CR2 to one card, and CR3 (or JPEG) to the other.

CR3 will save storage space, speed up write-to-card times and enable more prolonged bursts as the buffer will take longer to fill. It will probably also enable faster burst speeds than CR2.

Another major advantage is that during post processing, files will render and import/export faster, improving workflow.

entoman: I do love a good optimist :)

I hope you're correct on the subject of this being optional longer term.

More complex compression routines usually require *more* processing; so you may find that the buffer clears more slowly as the camera's processor becomes the bottleneck (rather than the card), and/or burst rates may deteriorate as the camera has to do more processing on each shot.

On the basis that Canon have launched this along with DIGIC 8, I assume that the camera probably will be able to process this efficiently in hardware, but it may yet have battery life (or other) implications at the camera end.

It's also possible that your computer may not be optimised for decoding these images, so you may find processing slower rather than faster - yes, they'll come off the card quicker, but you may find that each file take longer to open in your editing software.

At the end of the day, there's (usually) no such thing as a free lunch!

In reply to:

Lan: This article is incorrect. Canon uses lossless compression in all CR2 RAW files by default. Shoot some pictures, now take a look at the file sizes, they vary. That's down to compression.

CR3 is a lossy compression option.

Personally I wouldn't choose to use lossy compression for RAW files, if you're after the best image quality, lossless compression (a la CR2) is the way to go.

All manufacturers please note; I always want a lossless compressed RAW file. I do not want lossy.

@Samuel C: Indeed; that's my point in a nutshell :)

@matthew saville: From the article:
"Older Canon's that used the CR2 file format could capture either uncompressed Raw files or 'medium' or 'small' equivalents"

What I'm saying is this statement is wrong. Up until this point Canon have used CR2, which is a *lossless* compressed RAW format.

The new CR3 format appears to be a *lossy* compressed RAW format, which you can see from the pushed shadows example DPReview posted - note the clumpy grain structure, indicative of lossy compression (in fact it looks like JPEG artifacting).

Here's a teardown of the CR2 format:
http://lclevy.free.fr/cr2/
If you look the RAW image data in a CR2 is stored as JPEG *lossless* data.

CR2 has always been a lossless compressed RAW format.

matthew saville: PARTY LIKE IT'S 2007, CANON!

I've been using raw compression (as well as 12-bit raw) on Nikon DSLRs for over 10 years now, and for extremely high-volume jobs where I /barely/ require the image editing that raw offers over JPG, ...it is a huge space-saver, often saving 30-40-50% in file size compared to a 14-bit lossless file. I even have plenty of low-ISO NEF files that are /smaller/ than many of my same-resolution high-ISO JPG files. Yup!

Don't get me wrong, I'm glad to see Canon is finally going down this road. They'll probably get it much better in 1-2 generations. Just like how Nikon failed at mRAW sRAW the first go-round in the D810, but is doing better now with the D850. (Party like it's 200...6?)

But as usual, no mention of the competing brand's options, or the fact that they've been around for over a decade. Thus, queue the Canon fans praising Canon for this "ingenious idea" lol...

In all fairness to Canon, the article is wrong... They mean Canon has added a lossy compression option, CR2 has always been losslessly compressed AFAICR.

I can't wait for them to release this in a camera; of course knowing Canon it'll be 2050 and it'll be released with 4k video... Because, well, we don't want to cannibalise sales, do we ;)

Lan: Can we have some full frame FE pancakes with excellent IQ please Tamron?

I must admit I'm tempted by that Samyang too. Please post your experiences? I'm particularly curious as to how the AF performs compared to Sony native lenses?

I love the end result, but I think the final shot of the plate and the snowdrop itself is my favourite - it's stunning!

On article Rokinon AF 35mm F2.8 FE sample gallery and impressions (157 comments in total)

Thank you for posting this, it was just the gallery I was waiting for :)

I wanted to know how it would perform on the A7R2/3, and particularly at moderate apertures in landscape scenarios, and you've nailed it. Thank you!

Is the best lens ever produced? No. Is it an excellent performer for the size and cost? Yes. Yes it is.

In reply to:

mihoha: Will they introduce a new mount, stop making new EF lenses and only focus on the new mount? Opinions?

They already have a mirrorless mount, EF-M. To take advantage of the size benefits possible through a shorter flange focal distance, they'll have to use that mount or something similar to it.

I suspect they'll follow Sony's lead and just launch a full frame variant of their existing APS-C mirrorless mount.

Electronically EF-M is fully EF compatible, so just as long as you have a pipe with contacts your existing EF lenses will work with native performance on a mirrorless body.

On article Why brand market share shouldn't matter to you (552 comments in total)
In reply to:

sceneIt: "To cause any significant amount of brand switching a camera would have to be compellingly better. And people have to recognize it."

Let's be honest with ourselves here! Being able to push one photo by 6ev and other by 4ev is meaningless. Pictures don't even look right when you push them that far... If your whole picture is underexposed by that much for the love of god give up on photography and go work at McDonalds.

This nonsense over DR is foolish and distracts from the greater good of photography.

DPR should be embarrassed by their myopic obsession over a single specification...

@Peak freak: Precisely. I was a 5D2 shooter, and I'm now a A7R2 shooter for precisely that reason.

You don't use DR as a crutch to poor exposure, but it can really help if you're shooting a dramatic sunset with deep black clouds, and bright highlights. I also find it massively helpful for night shots. Shots I used to have to use HDR for are now possible in one shot. It's a game changer IMO.

In reply to:

Lan: You're absolutely right of course, "we're #1" is just marketing, & can be safely ignored.

It is quite easy to switch from Canon to Sony though. Use the Sigma MC-11EF and you can have all your Canon lenses working (with AF) on a nice shiny Sony body, which has far better per pixel sharpness, 4k video and excellent DR, all in one package that's currently smaller, cheaper and lighter than the 6D2 (the Sony A7R2).

People are actually switching. I've switched. That's despite personally having a significant investment in Canon glass (8x L series) and accessories (multiple Canon Speedlites). I can use all my lenses with AF, and the flashes all still work in manual mode. I was going to upgrade the flashes anyway, so that's no major drawback.

Unfortunately Canon seem unable to produce the camera I want, whilst Sony can and have! The 5D4 was nearly there, but they stuck a heavy AA filter on it for the wedding crowd... I would have bought a 5D4R and stayed with Canon, but they didn't make it!

RubberDials: Precisely, thank you :)

@sceneIt: By your logic, it's also a great idea to buy bad lenses, as you can sharpen those in post? It's not the same thing, and you know it! Detail isn't magically created by sharpening in Photoshop, you're just increasing the appearance of detail - at a potential cost of haloes and increased noise. A light/no AA filter doesn't come with those penalties. It's a tradeoff, potentially against increased moiré.

I assume you haven't experienced the joy of a sunset you can only shoot with a foreground using grad NDs or HDR because you're out of DR? I can get that shot in one exposure now, without any real noise cost or having diagonal lines from the grad or faffing around with HDR software. I'm not preventing you from sticking with Canon, I'm just saying there are other options. In my experience better, cheaper options.

In reply to:

PedroMZ: Market share alas does matter and influences one's choice .Take Pentax for example,they make excellent cameras and cost wise are very competitive , but their sales in the UK are small ,one of main few remaining high street outlets no longer stock Pentax and will not take accept the brand in part exchange. I am told that Pentax- fit 3rd party lenses are difficult to come by and indeed many of these lenses are not made to fit Pentax. The consequence of this is people are nervous about buying into the brand and it becomes a viscous circle .

> viscous circle .

That's certainly a sticky problem!
