Steve Balcombe: I'm sure this will be optically superb, but no IS (but also no tripod mount), huge extension when focusing, and focus-by-wire make it a tough sell. I wonder what the working distance at 1:1 will be?

@jnd - that's not working distance, it's focusing distance, i.e. sensor to subject. For macro you often need to know the clearance between the front of the lens and the subject, so you have to subtract the mount registration distance and the length of the lens when fully extended.

Alex Sarbu: I almost said: "not in K-mount?" - but then I've seen the weight, and stopped caring.

Not sure what you expect a 14-24mm f/2.8 to weigh. Even Nikon's relative lightweight is 970 g. Canon's 11-24 is slightly heavier and only an f/4.

J A C S: Some nitpicking: x% "faster" typically refers to speed, not to the time it takes. The time is inversely proportional to the speed. For example, 100% increase of the speed gives you 50% decrease of the time. Then in your test you may as well say that the improvement was 12.7%, not 11.3%.

No, that's 100% faster, but it does kind of sound wrong.

I wonder how good it is? And very importantly, how quick? After years of putting off the job of scanning old negs and trannies, it might just get done this year...

On article Grand Canyon time lapse records rare cloud inversion (125 comments in total)

Very impressive, but the cloud sequences, esecially the temperature inversion, were much too fast.

Steve Balcombe: Brilliant. Hard to pick one but probably the owl, it made me laugh out loud.

I've just looked at the 2016 winners - out of 16 shots, 4 are owls.

Some very nice work there, from skillful and talented photography to the best of 'right place right time'. But also a couple of inexplicable choices...

left eye: Even though Philips say it's ideal for video editors does it support refresh rates that are multiples of the common delivery fps rates?

Otherwise if it's fixed at 60Hz it'll only smoothly play 30fps or 60fps footage. 24fps (cinema standard) and 25fps (broadcast standard through Europe) will require pulldown to display, and so will appear jerky.

I wish manufacturers and reviewers would state the supported refresh rates of these products, for video this is essential information. This includes the refresh rates of EVFs when used with 24 or 25fps chosen capture rates, the GH4 and 5 for instance can only switch between 30 or 60Hz so displaying 24 and 25fps footage with jerky pull down.

snapa: So if you only have a 4k 60fps TV, is this cable/technology a complete waste of money?

BTW, anything higher than 4k is a complete waste, because the human eye can't see anything better than that on a TV or computer monitor, so what is the point?
There is a point when deminishing returns does come into affect, and we have hit that point with anything over and above 4k video.

@Nicolas06 - "BR 4K sales are not even visible. " - true, but I recently bought a 4k AVR and already had 4K TV so I researched whether it was worth upgrading my blu-ray player. There is so little content available that I've decided to wait. When there's more I'll buy the equipment and likely do my bit for 4K BR sales.

Pontoneer: The correct spelling is offenCe , not offense : we do not yet live in the United States of Great Britain .

For years I adhered to the popular view that Americans were guilty of corrupting English spelling, but then I learned that the two dialects of the language split before spellings were formalised. Not only that, but while Webster's first dictionary had many faults it was published decades before the Oxford English Dictionary. The net result is that we have a situation like Darwin's finches, that after settling on their respective 'islands' they evolved independently. Today they are no longer so isolated of course, and only time will tell whether they will merge again.

disraeli demon: Here in the UK we're used to $100 = £100 as far as lens and camera prices go, but i'd bet foldin' money that $100 ≠ £100 for this discount :-

There's no Black Friday deal at all in the UK as far as I can see, but there's still a few days to go so let's hope. I have some cash waiting for one particular lens if the price drops by £100...

It's ok, but it reminds me of when those "extreme ironing" shots were a thing, only without the comedy value.

On article Leica Thambar-M 90mm F2.2 sample gallery (214 comments in total)

I find myself totally conflicted by this lens. On the one hand the bokeh rendition is beautiful - and by the way the photographer has done a great job to demonstrate this so effectively. Stopped down a little the soft focus is magical (though not for every subject). But when the lens is wide open a veil comes down over the images which looks just like shooting through a not-very-clean widow, and I cannot find it in myself to like it. It's a very simple design with four elements in three groups. Maybe the addition of a floating element to allow slightly more correction (i.e. less under-correction) at wider apertures could improve it?

Fabulous.

It all boils down to performance. I'd love to have a 100-400 which is a pound lighter than my 100-400L II, costs a lot less and is black, but not if it's soft at the long end (i.e. as would be normal for a consumer-grade zoom) and not if I would lose AF performance.

The Arca Swiss compatible mount is good too, but what's the price and what does it add to the weight?

Bambi24: The title of this article is "MICROscopic".

The content of this article is "MACRO photography".

A microscopic image of a feather looks like this: https://www.owlpages.com/owls/articles/images/eagle_owl_feather_paolo_taranto-1.jpg

@vadims: If you want to be picky, it's photomicrography, not microphotography. The latter refers to taking tiny photographs - think spy cameras and the like.

Is it also correct to call it "super macro photography" as the article does? Not sure there's a hard-and-fast rule to answer this, but I'm comfortable with it.
