On article Sony FE 50mm F1.2 GM sample gallery (201 comments in total)
In reply to:

AstroStan: Not a perfect lens. Especially at 60MP resolution.

Image 52 has noticeable geometric distortion (e.g. slopped apt building on the far left). Pixel peeping shows some chromatic aberrations not all that far from the center (e.g. pine trees and needles), even at f/8. Focus near edges is poor, maybe FP curvature? Defects noticeably increase at f/1.8. There are no landscape sample images at f/1.2 though few people would shoot landscapes that fast with the notable exception of nightscapes.

Is this lens the "best" 50mm at the present time? Or is it just a good super-fast 50mm?

In image 52 (and 39) the lens is tilted up rather than held level. That is not 'geometric distortion'. Try looking for distortion in image 30.

I guess this review of the three main scanning apps in the world is much like any other that can be written: There will be pros and cons and complaints and praises associated with all three, depending very much on the scanner and on what's being scanned. Pick the one you like the most (or the one you dislike the least).

Perhaps the only really silly thing about this review is the complaint that Epson Scan occupies too much screen area when multiple panels are open and displayed simultaneously. Well of course that will happen, so don't keep them all open and displayed simultaneously! Why would someone need to?

guywithyashica: Not sure I understand the full benefits over the ea4 so may have to dig up specs and compare but I have been using the 4 for years with my (former) a6000 and now with my A7ii. I only have 2 FE lenses, the 28-70 kit and 24-240 due to the high cost of native glass. I use a Sony 30 macro, 50 f1.4, Sony 70-300 G, Tokina 11-16, Sigma 70-210 Zen (2.8), Tamron 90 af.... and the ea4 works well for me BUT I mainly shoot stills. Other lenses that have worked perfectly well but are not being used are my Tamron 28-300 (xr if), Maxxum 24, Maxxum 24-50 and other Maxxum stuff. I have never had an issue with comparability except for 1.5 and 2x converters with specific lens combinations but those were rarely used. The projected cost seems reasonable and I may switch if I see enough benefit, the lack of the mirror may be enough.

My a99 II has 79 focus points on the seperate sensor atop the lightbox and 399 AF points on the image sensor. Together, the two systems working in tandem provide 79 cross-type points."

The A99 and A99II are the ONLY examples of Sony's SLT cameras with on-sensor PDAF. All other SLT models have dedicated PDAF only - no OSPDAF.

Excellent! Now we don't need 5G.

"Please do not photoshop 1 subject into 2. It is not in the spirit of the challenge."

It didn't take long to find a violation of that rule, did it?

On photo Symphony of the wings ! in the A big year - birds 2020 challenge (13 comments in total)

Apparently nobody noticed the violation of rules in this 'winning' entry:

Processing rules:
No cutting and pasting

There were only two birds in this original shot - the others are the same two birds pasted in from a different capture. The giveaways are the identical facial features and neck feathers, and also the fact that artifacts are only present on the edges of two of the four birds.

Refreshing point of view ... but the dark sand has given the subject a hairy back.

The original had essentially no background to begin with. Looks like it was already magically suspended in mid-air. Re-do the demo with a normal photo and show us what happens.

"... they didn't make it for you ..."

And yet it's a sure bet that the vast majority of criticisms posted here are coming from people for whom it was not made. Funny how that works.

I'm very keen on astronomical phenomena such as eclipses, but this video is just ugly. Maybe if actual detail was visible (the Mavic 2 is certainly capable of high detail), and if the key part of the sequence was more than a few seconds long, it would be impressive.

On photo Portrait for Designer Olga Papkovitch by Tony Filson in the Female challenge (70 comments in total)

The only thing that bothers me is the weird fold of her dress behind her arm. It pokes out in such a way that it almost looks like the front of her body at first glance, if you know what I mean. Even afterwards it continues to be an odd distraction. Quite nice other than that, though.

"Nikon customer base is very broad, from novice to enthusiasts to prosumer to professional, that’s Nikon’s advantage. Olympus, Sony and Fujifilm can only cover a small part of that. So far there is no professional using their products. So when they develop products, even like retro style, they only try to meet these people and that’s only what they can do. Their customer base is limited anyway so they have limited view in developing products."

Pure arrogance. That was untrue when quoted and even more untrue now. Nikon had better get some humility and recognize the need to compete on actual merit in the full frame mirrorless arena instead of relying on past laurels to see them through.

Those huge nail polish (or fake nail) gaps are disturbing.

In reply to:

lattesweden: Now that we have seen more of this camera and know more about it, has anyone fully understood what the circular built in LED-light in the mount seen in the first video really is for? Is it for easier attachment of the lens in darkness so that one can see how it is placed versus the mount and connects correctly. Or does the lenses have fiber optics in them that leads the light threw them, or even maybe uses the lens elements to actually shine the light out in front to light up the subject like a ring flash does?

"... the circular built in LED-light in the mount ...?" This question clearly demonstrates that the videos are doing their job: Using irrelevant visual candy and dramatic music to confuse viewers into a state of childlike hypnosis.

sybersitizen: This new version appears to do its intended work very well, but...

Why does the program, like so many new Windows programs, have to LOOK like a Tinkertoy app running on a Windows phone? There's not a hint of the visual richness and dimensionality that Windows 7 on a REAL COMPUTER so easily provides. All we get is a dreary, gray, flat rectangle. Who declared total lack of esthetics (AKA the Win 8 experience) to be a good thing? Even the Start Menu icon is dull.

Why am I not presented with a drag-and-drop interface until AFTER I load up at least one file from the Windows Explorer interface? What's the point of that?

Why do we have to look at advertisements and panos made by other people every time the program is started?

These things might seem trivial on one level, but they truly diminish the value of what ought to be a visual showcase and something that's fun to use. Despite the functional enhancements, I'm actually considering going back to version 1.4.4.

"Noone forces you to use it. There are plenty of other pano stitcher apps."

Sounds like you haven't really read what I wrote.

1. I have happily used ICE for a long time, maybe even longer than you. Overall, it's a good product.

2. The latest version has nice enhancements but has become ugly (IMO) and advertisement infested, where the previous versions were not. I don't appreciate that.

3. Feedback on what people might feel Microsoft has done WRONG with this release should actually be welcomed by the developers, don't you think? Why shouldn't I provide that kind of feedback?

The price is the same as it was in the previous versions that were not ugly and advertisement infested.

Ah, thank you. It would have been nice for the developers to put the instructions in that space instead of what's actually there.
