Just don't peer to close, you might not like what you see under the clouds.

JhvaElohimMeth: Mhm, I didn't like it. Good colors and good performance... but only in good light. In backlight (and generally difficult situations) AF hunts a lot, and it's not sharp wide open, you have to stop at 2.8. I had also big problems with flare.

What camera did it hunt on, it could be the AF of the camera. Won't do that on a 5D4 for example and yes it is sharp wide open, certainly sharp enough. How do you know it wasn't back/front focusing. Most people know this is a great little lens and not just for size or IS>

Bambi24: "EISA CONSUMER DSLR CAMERA 2017-2018: Canon EOS 77D

well deserved

I know fancy having a category for the biggest selling segment. They had to introduce a mirrorless category for the terminally insecure.

Karroly: I do not care about this ranking. The best camera is the camera I have with me... ;-)

No, he tried the A9 but couldn't even fit his fingers between the grip and the 100-400 barrel, he then reached for his 400 f/2.8 FE, but was left clutching at straws, he then needed good DR, so went back to his D810.

Worrying to see the new glass lens increases saturation to garish levels on those what I presume must scientifically accurate renderings right; surely marketing wouldn't lie.

Rensol: I just learned light can bend when it APPROACHES smartphone lenses. Did not know it is possible! A swirly light path! What is it? Light turbulence?
Can you please clarify?

Well how else can you explain the rubbish image quality of smartphones. They must being using physics, but not as we know Jim, to produce these results.

Imagine if the iPhone could give the user this level of freedom. Impressive app, they should release it as a standalone app for the play store and app store.

Photato: These are features that could be easily implemented in dedicated cameras too.
But....traditional camera manufacturers have completely missed the boat on this because they are thinking in Phone rather than Mobile Computing Platform.
Yes Canon and Nikon, you don't have to get into the phone business to take advantage of all these wonders of the modern world.

Computing power in a smart phone is far higher than a camera, so pretty silly to claim this could be added to cameras with fw updates. But maybe they should put a Snapdragon 835 or A10 in our cameras so we can get 50 shots per charge.

Yeah that's why I said 20MP+, you do realise 12 < 20 right?

If you've seen the lousy output from those Sony 20MP+ phone sensors you'd wonder how on earth they sell any. Talk about the most overrated sensors on the market. Good to see Samsung sticking to 12MP.

Wow that new Sigma 14 f/1.8 is amazing, I'm ordering one as I type. Can't wait to capture the sun and stars in that much detail.

thx1138: But the DR is only 3-4 stops and it only shoots 1fpm, might as well burn it and buy a Sony.

Zeiss Ikon, und luxury! When I were young, I was so poor I had to take photos with tracing paper and a crayon fashioned out of mud.

photomedium: Sigma 1300 vs canon 1750 doesn't seem all that much less, all things considered.

Lens is only tested on the lowly 5D3 and even then it's not that great. The Canon holds up amazingly on the 5DsR and would destroy the SIgma in the corners and edges. The MTF's of the Sigma are very ordinary and the lens should have been labelled a Contemporary, certainly not worthy of the Art moniker. This is to the Art series as the Canon 24-105L II is to the L series, the b@st@rd stepchild. I suspect the Tamron G2 will be a better lens and is even cheaper. And Tamron usually has more accurate AF.

I'll take tack sharp and no OS over decent and OS any day no matter the price difference.

Thorgrem: Prices in the Netherlands are;

Stabilized;
Nikon AF-S 24-70mm f/2.8E VR ED 2235
Sigma 24-70mm f/2.8 DG OS HSM Art 1399

not stabilized
Canon EF 24-70mm f/2.8L II USM 1949
Nikon AF-S 24-70mm f/2.8G ED 1649

Seems to me that the Sigma is a bargain but the quality of the Nikon is better. I also don't like that the Sigma needs to update so now and than and that it's is a question if it will work all the time on new Canon/Nikon camera software.
Canon has nothing stabilized to offer and there non stabilized lens is more expensive than that of Nikon.

So no mention of the even cheaper Tamron 24-70 f/2.8 VC G2 as it's real competition.

No one that owns the Canon really is fussed about the lack of IS, it's 5 years old and is a stellar lens, easily able to handle the 50MP 5Ds sensor. I'd say if you stick to a 24MP sensor the Sigma would be perfectly fine, but I'd rather pay for the IQ of the Canon or Nikon for the big MP sensors

rbach44: Why does everyone make such a big deal about DPAF or on-sensor AF points? The D5 has neither of them and, according to reviews at least, seems to be one of the finest AF tracking cameras ever. Same thing with the Canon 1 series, Why worry about the underlying tech if it performs well?

I can’t help but feel like AF specs are the new focus since the MP race is pretty much over…

Why do people that have never used DPAF or other on sensor PDAF systems pontificates about why you would want it. Just try the damn thing for yourself and them you'll see why it's so damn useful and not just for video. Canon's DPAF in LV is about as fast as it's normal PDAF, you can even shoot continuous lay at 5fps with DPAF on 1DXII and it tracks very nicely.

technotic: No popup flash == no sale. Close Naikon, close.

Yes it's a convenient feature but really you think this is a deal breaker? Canon's never offered pop-up flash on a full frame and we buy a tiny 270EX flash unit that is way way better than any pop-up flash and only weighs 100g. If the camera is more ruggedly sealed lack of pop-up doesn't worry me.

Mateus1: Looks smaller = lighter. Maybe 0,7kg?

BTW, would you like to have D850 with 50iso native or with better 12800iso?

Clearly both, but most of all I want the DR to improve at least 1EV from ISO 400 to ISO 12800. As someone that also does wildlife and surfing you are often at ISO 400-1600 and by then the DR advantages are gone.
