On article Sony FE 20-70mm F4 G Sample Gallery (47 comments in total)

Viewing at 100% on my MacBook 13 inch screen is equivalent to looking at an 85 inch-wide print. (Did the math- it's about 0.9% of the full image in an 8 inch box.) In other words, what we see at this magnification will never be seen in actual use- and I've made some BIG prints in my time. So statements that this lens is not "up to a 60mp sensor" are nonsense if based on the 100% view. No lens on earth is without flaws if you peep those pixels hard enough. I am very satisfied by what I see in these sample images. I've pre-ordered the lens, can't wait!

Indohydra: This kind of organized theft has become common in San Francisco where it is related to the Union Square flash mobs. These guys were heroes. One sees Leica gear in the hands of some sketchy people who obviously are not interested in photography. I expect it will end up as essential bling among a certain set who like to identify ostentatiously with violence and thievery as a cultural statement. There is a market forming. Unfortunately groups of kids are starting to grab camera gear off tourists in the street no matter what it is.

What, exactly , do "sketchy people who obviously are not interested in photography" look like?

Would be great if the 300 covered full frame on Sony. Will have to wait for reviews. Some longer lenses have a baffle at the rear that can be removed.

I admire innovation, but this looks like the answer to a question no one asked. Has anyone ever said "I wash I had a mini tripod inside the tripod I'm already carrying around?"

QuietOC: I am interested. It is too bad it won't be a Sony branded lens with up-to-date Sony features like the 28-60.

Caitlyn- sharp and compact are what matter to me, not those other things. Pictures may be boring, not lenses.

It's quite incredible that many commenters feel qualified to criticize the technique and aesthetic decisions of this professional at the top of the field. They also show a lack of understanding regarding notions of truth and accuracy in photography in general, and National Geographic in particular. NatGeo has a long history of creating highly-produced images with sophisticated lighting and large support crews. And as others have pointed out, there is nothing "naturalistic" about the contemporary Stonehenge setting with its manicured turf grass.

Roland Karlsson: I think the idea is brilliant. You got a flash and a rather large reflector in a nice small package. And the price is reasonable. All good?

Nope, guide number 14? Even a very smallish external flash has e.g. guide number 28 and a normal one has e.g. guide number 56.

Or, am I wrong? Is the low guide number because the reflector is spreading the light?

I would have guessed that a bare bulb in reflector is less efficient than a speedlight-type fresnel head, but I just checked the GNs on the AD200 Pro- it's 60m with the bare bulb in standard reflector @28mm, and 52m with the speed light reflector at 35mm. One would assume the same for this flash- more efficient than a standard speed light head. Surprising.

This is an innovative design that should end talk that Godox is just a copycat brand. While the marketing (and video) seems directed at retro-seeking hipsters, this could actually be very useful for a certain type of work that I actually like- close range environmental portraits blended with ambient light. This flash will be light enough to easily hand hold, and will have enough output and a semi-soft look at about 3 feet from a subject. I'm going to try it using the tiny LightPix FlashQ radio sync transmitter and receiver. (Why can't Godox or other companies also make more compact transmitters for their systems?)

I agree with the other comments here that non-replaceable battery makes this problematic for professional or critical use. And I wish the flash sensor auto exposure worked with more than a single aperture? (An easy hack- put ND filter on sensor)

I'm looking forward to getting my hands on one, and maybe someday- a "pro" version with more power and interchangeable battery?

Why is there a twinkle (or I guess what people call a sun star)? I thought those were a result of aperture design and/or atmospheric effects? Neither are at play here.

On article Landscape Composition - Part 2: Balancing the weights (122 comments in total)

Nice follow up to your earlier piece. I'm surprised that you didn't mention content as having an impact on compositional weight. A human face, no matter how small will always have disproportionate weight, that's just how we're wired. That will apply to other recognizable objects and will also be affected by cultural backgrounds. And also as follow-up to my comment on your previous post- of course compositional balance and stability is not and should not always be the goal of a photographer- sometimes quite the opposite.

psartman: Good conventional composition can be taught. One person's compositional strategy can be explained, as it is here. Innovative composition can not be taught, IMHO. A balanced "pleasing" composition is not always the goal, just as a flattering portrait that makes the subject look conventionally attractive is not always the goal in that genre. Some great landscape photos can disturb or cause uneasiness in the viewer, to great effect. And don't get me started on "beauty".

Stevo, It's composition (or really any aspect of an image) that we are drawn to for some reason besides "Oh, this looks like other photos that I've seen and liked."

Thanks for the dialog Erez. I think your process is valuable for photographers to think about how their eye tracks through an image, and the notion of visual weight. I'm not sure I agree that a so-called balanced composition is the "beginning". I teach photography at a large university. Students often bring up "rule of thirds"- I acknowledge that as one way to achieve a certain result, but emphasize that they don't need to learn this or any other compositional rule. Rules are not just made to be broken, they are made to be discarded. As I said, your analytical approach is really helpful in figuring out why an image has the impact it does- whether balance, chaos, whatever.

Ellis Vener: This could be good. But the evidence I have seen is that the general future of lighting is powerful, high quality LED units capable of powerful electronic flash emulating bursts, such as the Light & Motion StellaPro Reflex S, which I’ve been using for the past few months.

In burst mode has one big drawback: it cannot pump out as much light as a a xenon tube flash (yet) but at shorter than standard x-sync shutter speeds it does not suffer from the drastic power drop HSS capable electronic flash does at those shutter-speeds.

But what makes a light like the Reflex S more viable going into the future is the oncoming change to stacked back-side illuminated CMOS arrays. Because of the way they are constructed, BSI CMOS chips let more light reach the light sensitive part of the chip. The architecture of Stacked BSI CMOS allows even more light through. More light getting through translates to much less noise at higher ISO settings, as well as faster read and scan times.

How does the output of high intensity pulsed LED compare in watt seconds to a traditional flash? That is, roughly 50 WS for a large-ish camera mount flash, 100-200 WS for off-camera such as Godox and the small Profoto. And what is the duration of these newer hybrid LED units? As you well know, one advantage of xenon flash is the ability to mix and selectively blend with ambient light, and of course- the compact size.

psartman: As soon as Sony builds radio transmitters into the bodies I'll be onboard with their brand of flashes. Also, would like to know more about the auto white balance feature. I've been waiting years for a company to figure out how to auto-adjust flash white balance to match ambient color temperature and tint. I don't think this does that. I have an idea about how this would be possible with in camera multi-shot processing, but no one from Sony has called me.....

I've also thought about the auto color balancing flash concept for a long time. A three-tube RGB flash is conceivable, but I think a more workable solution is a system that makes two exposures in quick succession. The first is flash at the highest possible shutter speed to block out ambient light (currently 1/250 on most cameras, but more feasible at higher speeds when global shutters finally become real). The second is exposed with ambient light only (same f/stop but auto or manually set shutter speed.) The two would be blended in-camera for a balanced jpeg, with the flash exposure at standard flash white balance and the ambient exposure at auto-white balance. Ideally, there would be a plug-in for post-processing LR or ACR that would allow fine-tuning of flash-ambient balance, as well as individual and global white balance. I think his can be done with existing technology and flashes, it would just require in-camera software and plug-ins for post.

psartman: If you are a serious photographer, either pro or amateur, a $70 price difference shouldn't be the deciding factor for something as important as a camera bag. It protects your gear that's worth a lot of money, and ease and comfort of use are a BIG deal. (The Sony body and 4 lenses I carry in my PD 6L sling add up to around $6500.) Is this really where you want to save money? Or on your tripod? I get it that cost is a big factor for many people, I'm not trying to be an elitist snob. Just suggesting that the price of a bag or tripod should be considered in relation to the cost of the other gear involved.

I'd pay an extra $70 just for the dividers alone . (I have had countless bags over decades, these clever folding dividers are by far the best designed and most versatile I've seen.) I don't have the Amazon to compare, but from the pictures and descriptions they are NOT identical. Quality of zippers and pulls, rain flap over zippers, swivel at strap attachment... I'm sure the Amazon bag is nice for $30, it's a good alternative, but not the same.
