io_bg: Wasn't the first 24-70mm f/2.8 lens the Canon one of 2002? If yes, then "professional and enthusiast photographers have relied on the flexibility offered by a classic 24-70mm F2.8 zoom" only for one full decade ;)

It was: https://en.m.wikipedia.org/wiki/Canon_EF_24%E2%80%9370mm_lens

Ebrahim Saadawi: I hope you give us some insight on the image quality of the 85mm L and how it stacks up against the Sigma 85mm ART and Otus 85mm, particularly in wide open sharpness.

Image stabilization makes it a very attractive close-up lens for actors.

If you could do a side by side with the 1.2 L that'd be really appreciated too, just to see if this new one maintains that "magical" look of the older lens in term of bokeh quality and colour and flaring and just the whole image. One side by side picture would do.

Plus Canon will definitely have more reliable focus than Sigma...

rrccad: it makes sense for them to keep up development, they have subscription licenses tied to LR Classic CC that fund it.

unlike LR standalone, there wasn't any real recurring revenue funding continued development as an another product.

IMO the naming could be alot better with this, it's confusing to say the least.

What could be a dfference between (old) LR CC and LR standalone? Couple of lines of code or some switches in code builder?

Absolutic: I'd love a jacket with several pockets large enough for big lenses

Small mirrorless, small gorillapod and couple of other small accesories can be put into the lot of jacket, nothing special here. I was expecting something to put my usual kit - 5 lenses and pro DSLR - in :)

elgol20: Where is the standalone version?

Well, Adobe's revenue is bigger than before, from that point of view subscription works extremely well...

Mike CH: Just one question: Why?

I use Paddy for Lightroom, which does pretty much the same thing. The purpose is to speed up process - no need to click on tiny sliders

blackcoffee17: I wonder if a drop-in filter would not be a solution for these kind of UWA lenses, just like the big telephotos have.
It might make the lens 1-2cm longer but wouldn't have to buy a massive filter mounting system and spend a fortune on huge filters.
At least for ND filters would be quite practical.

Sorry, haven't realized i sent this 4 times now. I was getting 404 errors when tried to post earlier.

It is. It's impossible to make them perfectly planar, they degrade image quality, adding haze, are easy to scratch... it's only plastic. Have been using them on Canon 14/2.8 and Irix 11/4 for coupoe of years only if it is an absolute must.

Gel filters are crap. I wish Aurora Aperture makes glass rear filter holder soon... http://aurora-aperture.com/2017/04/21/powernd/

maxnimo: So the Backpack and Messenger are constructed with genuine Italian leather, and also made with water-resistant nylon? You mean half leather, half nylon?
And do you realize that when leather is exposed to moisture or humidity it can get quite nasty?

Very true (and sad)

What about possibility of shooting in raw? This is the only way why I decided not to buy it....

Sorry to say this, but results correspond with the camera used...

The magic of smartphone regarding photography is you always have it in your pocket and instantly ready for an action. As soon as you need to carry other components, think of their batteries, mount other stuff prior to shooting etc., you miss the elegancy and simplicity. It can be good for specific applications (although why would anyone built such a combo if he can buy an all-in-one camera), but it will never become mass popular.

EXX: What is the difference to any other 35mm lens that I set to f/8 and focus to infinity?

Big. Focusing to infinity doesn't work, in order to have maximum depth of field, you need to focus to hyperfocal length, which in this case is 5,1 m.

Martinka: Is it really necessary to have complicated twin focus motors in wideangle lens? I don't think this kind of lens is critical in focus speed and accuracy...

Maybe it's displayed in the camera screen...?

Even old Canon 16-35 can focus quick and accurate without complicated twin-focus design... I'm just saying to me it's overcomplicated with bigger chance to break for no or very little advantage.

Yes, I'm a sports pohotographer and still don't think focusing such a lens is a complicated thing - unlike 70-200, 200/1.8, 85/1.2 and other of my lens. Other manufacturers can do it after all...

panchorancho: What's the point of going Sony FF, when lenses are the same DSLR size? What a gimmick!

Sensor quality has nothing in common with mirroless...
