I miss Kata bags. Apparently not made anymore. I still have two and use them regularly. Shame when a good product just fades out of the market!

On article DPReview TV: Sigma 150-600mm F5-6.3 DG DN OS review (46 comments in total)

Well done review as usual! The lens is particularly intriguing for A7Riv owners - cropping those 60mp files can eliminate the need for a teleconverter. Shooting in crop mode at 600mm produces an effective 900mm focal length, and would presumably offset any corner sharpness concerns while still producing a 26mp Raw file. I think $1500 is a very reasonable asking price to get into that kind of long range shooting. Will Sony discount its 200-600 to compete? One can hope...

The price points are a little closer than implied here, for folks willing to shop and wait for a deal. On the Full Frame e-Mount thread last week shoppers were finding the a7Riv (new version) fur under $2500 on Amazon. I haven't shopped the Nikon but assume it sometimes dips quite lower than MSRP as well.
But I appreciated the quick technical comparison of these bodies for a specific purpose. Videos like this are not usually the final answer for those looking to decide, but certainly add to the available considerations. Oh, and I have used JPG for astro photography! (It can be a useful comparison--or confidence builder-- to see if the in-camera NR is better than what I can achieve from RAW in the same conditions.)

I've had an a7Riv since November 2020. Never had occasion to wish for a higher res screen, and the pixel count on the rear LCD never factored into my buying decision. It's something I skimmed over in the spec list, caring much more about other aspects of usability & handling, which were/are great (for me).

Resolution improves in LCDs over time, and Sony made a change to update a product with more current specs - nothing wrong with that! If they had tried to call it a whole new model and not just appended the "a" to the name, we'd have endless complaints about a "model upgrade" that didn't really change much on the camera.

On article DPReview TV: Sony 50mm F1.2 GM review (372 comments in total)
In reply to:

Francesco De Lorenzo: There are comments of all kinds. It is not clear whether the lens can be taken into consideration or not. Is it worth its price? 50mm is my favorite focal length, and this GM seems remarkable to me. But before investing over 2000 euros in the purchase, I ask you: it is better to consider other lenses (eg Sigma 1.4, Sony 1.4 etc.)? do you find the optical performance of the lens unsatisfactory? Thanks to everyone for any advice...and sorry for my Google translated english

I suggest those considering a prime lens and don't have lots of extra money lying around approach it this way: Try an inexpensive lens in the desired focal length first, to determine if that prime focal length really is what you thought it would be for your photography.
If it works for you and you are happy with the results, you avoided spending too much on your lens - congratulations!
If it didn't work out, decide what you find wrong with it and shop for a replacement with that in mind (after selling yours on the used market). You may be disatisfied by focus speed, bokeh, aperture not wide enough for your narrow depth of field goals, or maybe it's too big or not weather sealed enough for you. You may not need the $2000 option to fix whatever you found wrong with it though! I have tried primes at 30mm, 50mm, 35mm, 28mm, and typically I'm happier with my zoom that covers all of those lengths. So I'm not the target market for this one. But yeah, it's nice!

Great addition to the team. I rented a few lenses over the years from LR, always had a good experience, and purchased some former rentals because I knew they'd be in good shape. Never disappointed. His truth telling about lens quality (and deficiencies) has benefited all of us by forcing manufacturers to improve their products.

Great and informative review - thanks! I like the pace and the tone of these videos. You can spend 15 minutes and learn a lot. The production quality is so much higher than all the DIY gear reviewers out there - glad DP Review landed you guys.

Imager of: And I the only one wanting less MP on these new cameras. I mean come on. We post stuff on Facebook for gods sake!

Target market for the a7r line has always been professionals seeking hi-resolution stills. This $3500 camera is not for instagrammers who can get what they need from their 20 megapixel phone cam. Yeah, it's a large file. Studio pros and large-print landscape artists will appreciate that, if they're not already using a 100-mp medium format body. (But I admit... admirable results even for 20"x30" prints can already be achieved by 16mp or 24 mp cameras.)

JP001: The bump in megapixels was a given. But apart from that, I was expecting a full touch interface and was hoping for a tilt-swivel screen. No mention of any of that. Sony has great touch technology, just look at their Experia phones. And they can do a clever screen, just like the one the A99 II has. It's not something they have to invent all over. And also no mention of 16 bit files or compressed raw files without any loss in quality. Doesn't mean it's not there, though. Still hoping... And I hope I don't have to get a new flash controller because of the new interface on the hot shoe...

The utility of the full tilt/swivel can also be a vulnerability. I have it on my a77ii and that's the only part that has had mechanical issues in 5 years of heavy and varied use now. (Bundle of connecting wires gets twisted repeatedly in that design, eventually some can short out or eventually tear.) So I see this is a design decision on the a7r_ line to accommodate the compositional need for tilt but avoid the vulnerability of swivel.

It's not fair to include a happy smiling husky in a sample gallery... who could knock a photo like that? :)

I like Roger's articles, even his quirky two-line lens summaries on the rental site. He gets to the point and shows serious technical chops while keeping it accessible for us non-physicists. And even when he's sharing something he's clearly enthusiastic about, he keeps the tone pretty even and reasonable. Great stuff to feature here-- thanks.

JEROME NOLAS: With 16-50mm again? What a shame they can't built a sharp lens for $500...

The 16-50/2.8 for Sony A mount is very sharp and affordable, unfortunately it's only appreciated by a shrinking user base of a-mount APS-C users. I'm surprised Sony hasn't replicated it in an E mount version if they intend to continue the APS-C mirrorless line.

I'd never criticize any of these unless I had credibly demonstrated my own ability to produce anything similar. These are fantastic images to view in their own right. And I think the awards are appropriately categorized in their respective niche specializations - I doubt any of the telescope photographers in the contest are upset that a landscape did so well in it's separate category! I'm happy they were shared and I commend the artists and their knowledge of the tools used in these highly technical (and easily botched for most of us) approaches to image making.

MrBrightSide: The D200 also had a banding problem but the geniuses at Nikon pretty quickly identified the problem and came up with a solution.
Nikon may be horrible at marketing and customer service but their creative/technical talents are far beyond what we in America can imagine.

This too shall pass.

I only scanned through enough to read two of your comments, MrBrightSide, but find them both to have these vague generalizations about "we in America" and "we in the West" - are you really convinced that creativity and technical aptitude are tied to one's geography? What a simple way to view the world and your fellow travelers in it.

In reply to:

winkalman: Serious question, as someone who hasn't used either, is eye AF meaningfully better or different than face detect AF?

When shooting with shallow depth of field, Eye-AF can give better results by finding the closest Eye rather than the closest point of the face, which is often the tip of the nose. Sony in on their 2nd or 3rd iteration and yes, it's a benefit. I have the a77ii and can't use eye AF in continuous focus mode, but the more recent mirrorless bodies and probably the a99ii can do continuous eye-AF. I'd like to hear a response from wedding/event photographers though - my experience is from shooting family candids mostly and an occasional casual event.

Link | Posted on Aug 23, 2018 at 15:38 UTC

I think Sony's a7iii is priced right to keep it in the full frame mass market appeal zone, not just for long-time enthusiasts and prosumers. If they could score some shelf space for it in Costco and Sam's Club in the US, and not just the camera stores and online outlets, US sales would see a quick jump. I know my neighbors who were casual shooters made the jump to full frame because Costco was selling D600s and D8xx bodies around Christmas... Just more marketing logic that seems to elude Sony but help its competitors.

Nice edge-to-edge sharpness on the bricks, and it's great to see a combination of sensor resolution and lens quality and photographer's eye capture a fun slice of life like this. At 100% you can see facial expressions, clothing details, car makes, etc.

I can't tell if this is internal zoom or does the front element extend at the long end of the zoom range? I keep thinking if Minolta could do internal zoom in the 1980's and produce the sharp beercan 70-210 f4, why aren't more modern zooms doing that? Hopefully this one is. I don't see two values for the length spec, so maybe?

I bought a Pixel 2 to replace my Sony Experia Z3V. After a couple of weeks, let me summarize the ways in which this is a game changer for me:
- I no longer think of my DSLR (a very capable Sony a77ii) as my go-to camera for family candids and exploratory walk-around shooting.
- As a result, I'm not packing my DSLR with me as a daily shooter anymore. The Pixel 2's quality is more than good enough, and even allows confident shooting where the DSLR would be too slow or too conspicuous.
- I'll no longer be shooting my DSLR (in RAW) for family candids, casual events or family history record shots; I'm done adding to my backlog of RAW pics waiting for PP. The Pixel 2 is the reason why. My DSLR is now just for dedicated photo outings and landscape or formal portrait shooting where substantial post-processing is planned and considered before the shot. And when I upgrade the Sony, its replacement will be focused on those more formal duties only, extending its life and avoiding unnecessary risk.

On article How to photograph the northern lights (80 comments in total)

Thanks for taking the time to write this out and share your knowledge. Like many photographic techniques and experiences, this can seem simple at first glance, but the wide disparity in quality of Aurora photos "out there" proves again that experience and practice, not just gear and knowledge, will make a better outcome. Planning and luck are necessary for the best conditions I assume. I appreciate your discussion about focusing here. I think that's the part a lot of novices are getting wrong - so much color in the sky can overwhelm a photographer and make them rush through frame after frame, afraid to miss the spectacle, only to find later that the focus was not carefully tuned for maximum sharpness.

Maybe one day I'll get the chance to be the novice, learn from my mistakes, and eventually get some great aurora shots of my own. Thanks again for your knowledge so I can use it when that day comes.
