LJ - Eljot: A4? A4 is not a ratio, A4 is a particular size. It is 297mm by 420mm. A3 and A5, even B4 and C4, all the DIN-series sizes have the same ratio. The ratio is allways approximatly 1:sqrt(2).
US letter is also not a ratio but a certain size. It is 8,5" by 11", wich is a ratio of 17:22.

Schape or ratio is the same in this context because we can assume the crop will be rectangular. The ratio is the same that a DIN A4 sheet has, but also any other DIN series format. May be bit pedantic.

Ups! Wrong row. Sorry!

anticipation_of: Do many people out there shoot in crop modes regularly? I always shoot at my camera’s full resolution, and then crop from there in post if I feel the image would look better with a different aspect ratio. Sometimes I have a particular aspect ratio in mind when I’m shooting, but I still crop later; in fact it’s a standard part of my workflow to pull up the crop tool right at the beginning of an edit and play around with different framings. I feel like I get more flexibility this way (e.g. if I want a little more or less sky than I thought at the time of shooting, I can have that) and have more opportunity to maximize the resolution of my photos, rather than throwing some of it away right at the beginning. Am I in the minority here?

I like the crop mode in a digital camera very much. It helps much for composition if you have a crop mask in the VF or on the screen. Unfortunalty my camera only has its native 4:3, the 3:2, 16:9 and 1:1. I miss 6:7 very much, because thats my prefered format for portrait orientend pictures.

On article Buying Guide: Best cameras for students (68 comments in total)

No, defenitly not a Nikon 5xxx or 3xxx camera. As a student you are likely on a budged and will chase ebay and local stores for used lenses. There are tonns of good AF-lenses from the 90th wich are inexpensive but will not autofocus with those cameras. At least buy a 7xxx camera!

On article Rokinon AF 50mm F1.4 FE: sample gallery and impressions (142 comments in total)
In reply to:

Ebrahim Saadawi: If I am looking for the 50mm f/1.4 "look" with AF for the least money, I'll get a 300$ Nikkor 50mm f/1.4 AF-D, or a 400$ Canon 50mm f/1.4 USM and if I wanted high-end optics I'd go for the Sigma 50mm f/1.4 ART (just 250$ more). But, this is just a no sale, great resolution even wide open and great contrast but the bokeh and CA and whole look is just, off.

Maybe as a special look for video...

The Nikkor would not fokus at all. It would not even focus with all Nikon cameras.

On article Buying Guide: Best cameras for parents (137 comments in total)
In reply to:

OremLK: I maintain that Canon is killing it at the low end even though they're not doing so hot for enthusiasts/professionals these days. For parents or beginners or even just any hobbyist who isn't going to print big, it's hard to beat Canon's APS-C lineup and lens ecosystem for value. If you've got less than 1000 to drop on your whole kit, Canon's the way to go.

Sensor's too small on the MFT cameras. Sony's lens lineup sucks. Nikon's live view is crap, and they don't quite have the budget lens selection Canon does. Fuji's lenses are great, but they're too expensive in this price bracket.

Process of elimination.

I do not agree that mFT were to small. If they have the best value is questionable. What about Pentax? They have really goog offerings in the lower segment.
But kids seldomely hold still and move quick and erratically. Everyhing below a Nikon D5 Or Sony A9 would be insufficient.

Triplet Perar: If true, they are terribly wrong in that decision. But, unfortunately, their decision is a direct result of a rising tide of common ignorance and dull-wittedness spread in online forums, blogs and Youtube channels by the ignoramuses, trolls, the measurbators, clickwhores, and by the gatekeepers of the so-called "digital" photography famdom, like DXO.
Welcome to the dark ages of photography, where MTF charts tell "the truth".

Some of the Milvus are classics is a new barrel.

In reply to:

shademaster: Not many very challenging scenarios for the AF. Wide angle lenses and narrow apertures (everything is in focus). That's one of the main disadvantages of the E-M10 vs. the E-M1 or panasonic, fuji, sony, isn't it? (I know it's a commercial and not a review, but...)

Rent a real truck!

ovatab: folks who watch old movies usually can not tell difference between 4K and full HD from normal viewing distance

If it is 16:9 ratio then 40° of horizontal FoV should be about 1.2x the diagonal. It is said that people with 100% visus can't see above 1.6x diagonal any pixels. At 1.2x should be a noticable difference between FHD and UHD. But that is with special viewing targets. With old movies there is often no noticeable difference. But then again: What is old? Was it captured on 35mm or 70mm Film and so on.

What is meant by normal viewing distance in that case? Diagonal of the screen?

Boeing skipper: Finally, a USB C connector. You see that, Canon?

I wonder how it improves the livew image in tethering.

Boeing skipper: I'm glad they didn't increase the sensor resolution.
If they went for a 70+ mpx sensor, I would have been turned away. But at 42 mpx I'm seriously considering it.

I would not bother if it had 96 MP and alway output at 50% with 6000x4000.

Budget MFT like the YI Technology M-1 don't have IBIS. Ah, and most Panasonic neither.

SteveY80: An impressive device and considerably cheaper than an equivalent MacBook Pro.

I have a mild preference for Mac OS over Windows 10, but for me the choice would probably come down to details, like the quality of the screen, keyboard and trackpad.

Ok, I am sorry for being rude. The german microsoft site I can not find the 15" model.

"The new models come with Intel's 8th generation Core processors and NVIDIA GeForce GTX 1050 and 1060 GPUs, making them "up to five times more powerful" than the original model and twice as powerful as the latest MacBook Pro."
I think I can read.

Dianoda: No mention of display gamut? Are these wide-gamut/DCI-P3 like the Studio or do they continue with sRGB like the previous-gen Surfacebooks?

But wide gamut messes up the whole windows interface. You have accurate colors in colour managed application only. The display would need an sRGB mode.

Really? The AMD Radeon Pro 560 in the MBP should be in the same range as the NVIDIA GeForce GTX 1060 in the Surface. Thats why I can not realte to the claim "twice as powerful as the latest MacBook Pro".
