The Sony A9 mk2 cannot shoot 4k in ambient temperatures above 40c, so cant be used in the Middle east for war reportage,and the partial mirror blocks 30% of the light. Add a limited range of lenses and it looks like pretty dum alternative to a pro Canon.

Great to see Sony taking risks with your money. If the A9 body is overheating what will happen to the A7 size with full 4k.

lhkjacky: It seem Sony A99mk2 just fixed all the cons in 5dmk4.

42.4MP BSI FF sensor, 12 fps, 5-Axis IBIS,
399+79 point Hybrid AF, AF sensitivity up to -4EV, Eye AF
4K MPEG 4 AVC/H.264, Slog2/Slog3, Gamma assist,
Full Tilt and Swivel Articulating LCD,
EVF, Peaking, Zebra pattern, Clean 4k HDMI output,
Slow~Quick Motion, 120P in Full HD.
Highlight-Weighted Metering,
Spot-metering link to focus area,
Shutter Life Expectancy 300,000 cycles

The A9 mk2 wastes 30% of light with the partial mirror and 4k video will overheat the camera in ambient tempertures of 40c or above. Sony are happy with this. But a Canon camera will be reqired to work in war zones like Iraq where temps can reach 50c. If you want an advanced camera buy a Canon if you want a gizmo buy a Sony

Most of the complaints against Canon are video related,
However I think video is reaching a point where 4k full frame and higher are no longer compatible with DSLR body architectures. The thermal management design required to implement a reliable full frame 4k is highly complex and would require a compromise in the design of a good stills camera. I not sure I want my lovely stills sensor cooked to the required 4k temp. This could also be why Sony is looking again at the A mount. Any thoughts?

What! No 4k video. (Joke!).

Well done Fuji. I hope prices will come down as other manufactures compete.

inorogNL: I was a bit confused about this article .... untill photokina anouncements

They look great in headlines but 6k for a few seconds, a Sony with 400 auto focus pixels on sensor. Try 30 million on the 5d mk iv. And the Sony will come with the usual bad colours etc. Anyway at least Sony realise that their cameras are too small so back to the A mount future, but the partial mirror system throws iq away with no real benefit.

Canon takes a little longer than say Sony to bring out its new technology, but at least its tested on 1 or two cameras before becoming main stream.

Also they deliver reliable products that dont overheat or rushed out with poor features. 80% of pros use Canon and not "my little Sony's" for me colour and IQ are evverything for Dpreview its all about paper tech.

Given the economic times we live in i hope Canon will continue to survive by being cautious. Especially given the natural disasters the Japanese companies have had to endure.

I find DPREVIEW potentially the best review site very disappointing, its lack of creativity and poor management that allows techheads to dominate.

Photography is an Art form that uses technology not the other way round.

A truly great review site with a decent editor does not need such click bait headlines.

The canon 85mm f/1.2l mk2 is sharper than the 85mm f1.8 at all apertures so why not use it for the tests.

In reply to:

Cytokine: Most of these samples are at 5.6, f4, or 2.8, and at these apertures almost all the good 85's are sharp.

The Bokeh is so bad I cant believe a Japanese company made this lens, it looks like Nissan Bokeh. Sony even made a machine to predict the bokeh?????

Why so few 1.4 samples? Is it that bad that the reviewers cant or dare not post any.

I am no Zeiss fan, but they would never put their name on something so bad.

There are plenty of lenses as sharp as this one, with better bokeh at a fraction of the price.

Did Zeiss refuse to put their name on this lens design? Maybe it should be called the Grand Mess.

Reply to Charrick.

Yes Dxo mark need to explain what the masurements mean in the real world, and how suitable a lens is for its intended application, just look at the confusion in the above posts regarding dof.

Does 25 years in pro-photo equipment and lighting research & development count as experience?

It is a good sharp lens but not a portrait lens, as some people will find out when they photograph their girl friends and family, unless they are being prepared for laser surgery.

You might actually be right! for years lens designers have realized that portrait Lenses need to have slight optical defects built in. But DXO Mark etc., with their lack of experience criticized those lenses, the danger of this is we now get lenses that are perfectly unsuitable.

On article Heavy hitter: Sony FE 24-70mm F2.8 GM first shots (349 comments in total)
In reply to:

Flashback: Seeing past the poor lighting, and quite frankly the girl model who doesn't look too well, this lens shows a lot of promise.

All the attention seems to have been on the 85mm F/1.4, but it might just be it's the 24-70mm that becomes the star of the show.

I agree the 24-70 f/2.8 could be very good
The 85 1.4 with the samples shown so far on other webb sites. Is the old story of too much sharpness fighting the bokeh and complexity of aspherical portrait lens design.

Foreground blurr is smooth but the transition zone is frankly weird although this might produce a "new look".

I dont own shares in Canon Nikon or Sony and probably neither do you. If you have not done so already do your self a favour, go and try the Canon 85mm f/1.2l mk2 on a 6D or any modern camera. Set it to 1.2 take a few photos.

Or a full frame Nikon and their 85mm 1.4d or g.

Dxo Bark and Dippy review are not known for their photographic talent. They measure scores but have no idea how to translate this to real world photography, or how this relates to human perception or vision.

If you have ever used a long lens on a small camera body you will know how hard that is. So ensure your camera can balance the lenses you hope to buy.

I hope one day Sony will produce great cameras but they are not there yet. The human eye can only see about 10-11 stops of dynamic range under quick scanning conditions your screen or printing even less.

Few people can agree on how to measure dynamic range or how Iso can be compared evenly across all cameras.
Or even how raw converters can be compared.

Hold your thumb at arms length the size of the thumb nail is the area that the human eye can see in focus at one time.

Forget hype try everything for real and choose what works.

Thankfully my Canon camera does not have a Sony tweaked Sony Sensor they seemed to be tweaked to score well at DXO mark and not for real world photography.

Colour and tonality looks worse than an i phone.

The Technical quality of the bokeh from the samples appearing everywhere is the worst i have ever seen. Like wearing the wrong glasses it makes you feel sick.

In reply to:

Sannaborjeson: Such poor quality jpegs at 100%... makes it totally impossible to make any opinion on the lens.

Also, why don't you hire a pro photographer for such samples? Only bearded guy is ok while the rest of the photos are thoughtless and of no value.

Pro photographers are too expensive and they mostly use Canon cameras which dont work

Many thanks to Roger Cicala and his brilliant team for the great technical articles.

Sony have always been quick to provide great products in every spere of electronics, however their track record on reliability has not been good, usualy failing because of something simple like hinges on my vaio, keys falling off. A led failed on a 2000 usd hi fi and stopped the whole system. Car hi fi failed because of poor quality cable to the display. 2 hi end cd players failed after two years. The list goes on and on.

My Nikon D200 still working like a Trojan my Canon products so far (touch wood) still working like new.

I hope that you guys have more luck.

In reply to:

jonny1976: the problem is that you must use a canon camera to obtain the most of it, autofocus.. canon produces lovely lenses, camera so so.

I have been using dslr cameras for 45 years while less than 9 or 10 stops of DR might be a problem none of the current Canon DSLR cameras are a a real problem so DR is well down the list. Good colours a clear view finder uncluttered by 200 af points or not having to look at a tv screen are far more important.

Then there is lens choice Canon is No. 1 even zeiss consumer products dont compare.

How on earth did we photograph anything before autofocus. Todays photographers seem very pathetic. Spurred on by the Techheads at DPR.

I like Sony and have bought 30+ products from them over the years none of them lasted very long.

All the great painters in the past used compressed dynamic range. Yet everyone on here seems obsessed with this minor point, it is way down my list.

I hope Canon keep making great reliable cameras with great IQ. And let the idiots worry about a shadow behind a rock.

There are great camera reviewers out there like Bythom unfortunately none work for DPR just look at the sample pictures.

As for DXO Mark they are a bad joke.

Interesting that the Sigma like Zeiss top lenses has more onion rings in the bokeh than an onion bargee the new Canon has none.
Usualy caused by the use of molded asphericals v Canons ground and polished ones. Understandable for Sigma's value engineering. But not in the high cost Ottus.
