PaulSnowcat: Well... Canon makes good lenses... Looks like it moves to become a 3rd party lens manufacturer :)

To PaulSnowcat: Do you really think it is fair to compare a second hand price of the Canon 70-200/4 (judging by the price you paid, probably the old non-IS version), to a brand new Sony equivalent? I checked the list prices of these two lenses on B&H, and it is 1099$ for the Canon and 1499$ for the Sony. While I agree that in this case the Sony is too expensive, there are also lens examples where the opposite is the case. But for sure there is nothing like your claimed 3-8 times price difference, at least not on the planet that I live on. Now, I don't know in which world you live ... ;-)

PaulSnowcat, what price difference is 3-8 times? In which world?

In reply to:

quatpat: Am i missing something, or is the automated AF fine tune only saving one value per lens? No different values for distances or different focal lengths? Many zooms need different settings at different focal lengths though.

I guess it is nice to have the feature, but the "fine" tune could definitely be a lot finer.

If you send back lenses that need AF fine tune, that sort of misses the point of AF fine tune then...!

upptick: Probably fake news, but still plausible. I lived / worked in Switzerland for two years. It's a hyper-regulated quasi police state. A pretty one though.

Be careful, for saying something like that (and spilling it carelessly to the Russians) we Swiss can put a fine on you , or impeach you or covfefe you - or whatever!
(I wonder where you lived in Switzerland... Bergün? ;-)

Wow... Incredible sharpness for the fact that it is a relatively "cheap" zoom! And the bokeh isn't overly bad either, congrats to Sigma!

On article Alpha-better: Sony a9 versus a7R II (503 comments in total)
In reply to:

hatem95: I am a Sony fan, and I owned 4 previous mirrorless Sony's and I will get the A9 but please stop this media hype. A9 may have super AF, etc.... but the form factor is incompatible with using it as a sports camera in the field. A sports camera needs Sports lenses and these lenses are Huge , I have totally abandoned using my Sony 80-400 with the A7rII not because of AF issues but because it feels very awkward and imbalanced in my hand. if Sony is that clever they should design a small superfast sports lenses to match. otherwise, the A9 is not a sports camera

Technically speaking, producing "small super fast sports lenses" is almost a no-go, but hatem95 isn't completely wrong. There are some efforts going in this direction, with maybe the best example being the Nikon Af-s 300mm f4.0 E Pf Ed Vr, which weights roughly half of a traditional 300mm f/4 lens while maintaining excellent optics and build quality. With its Fresnel element and light but solid construction, Nikon managed to give us a hint of the future, which hopefully will be that fast long lenses become more handholdable. It would be a great opportunity for Sony to put their efforts not only into minimizing the size and weight of their cameras, but also that of larger lenses. If they would bring out, for example, a lighter, maybe handholdable 400mm f/2.8 of around 2.5kg in weight, now THAT would attract professional sports photographers across the board. And as Nikon has shown, with the right glass and materials it should be technically possible.

Peter Dhaeze: With a Canon EOS 1DX mark II I can shoot 60fps 8.8 Mp JPEG's with 'tracking', without blackout and completely silent (=4K video MJPG). What is so special with the 20 fps 24 Mp Sony A9 when you need the exact right moment? With 60 fps the hit chance is much higher. Not?

Never mind, answer was already given to Maksim.

In reply to:

Gnostos Agnostos: The 20 frames per second are impressive but a hidden disadvantage of all Sony a7 cameras is that at burst mode the raw files are downgraded from 14bit to 12bit.

The Sony RAW files will have better shadow recovery at 12bit than the Canon RAW files ever had at 14 bit...

The simple truth is, smartphones are way more convenient than any other camera: They are flat, always with you, and connected to your social media. So for 99% of the users, this is all they need. The other 1%, the ones who care about image quality more than about instant publishing on social media, buy a DSLR or mirrorless.
But in terms of practicality for everyday use, the smartphone cannot be beaten at the moment, no matter what manufacturers put into a DSLR.

Well, a full frame lens is a full frame lens, no matter what body you put behind... This said, it seems like a lot fo people are mislead by the relation body to lens size, which make these lenses in the photos look bigger than they really are.

Some of the commenters here below seem to forget how small the A7 bodies are, which is why they think that the lenses are huge in relation to them.

GodSpeaks: "extremely useful for Macro Photography and Portrait Shooting "

Portrait shooting? Strange, but I have never had the desire to do 2x marco shots of the people of whom I take portraits.

Yep, God needs activate brain before opening mouth.

quatpat: Why don't we see any photos of the extended lens? Too ugly to show?

Yes that's true, but there is still a tube extending in the front. It proabably looks similar to the 70-300L when extend:

On article Photokina 2014: Canon stand report (69 comments in total)
In reply to:

Jon_Doh: Canon continues to fall farther behind the competition. There will come a point in time when they can no longer rely upon "it's the entire system that matters" and their lens line up. True, the 7D II is a great upgrade, but the 5D III is long in the tooth and over priced and the rest of their line up simply stinks.

Canon is not bringing out anything really new and fails to replace their stone-old 100-400mm, Nikon does not seem to want to take the D300 to a D400 and concentrates on full-frame only, Sony brings out only FE mount lenses and completely forgets about A-mount... where is this all going? Are we doomed? Will there be no tomorrow? Maybe Nostradamus got it all wrong, and it is all going to happen right now, at Photokina 2014...!!!

On article Sigma announces two 150-600mm F/5-6.3 DG OS HSM zooms (138 comments in total)
In reply to:

Frank_BR: If you think this lens is too heavy, you should not forget that you still need a tripod weighing as much as the lens itself. I.e., using this lens incurs an additional weight of about 6kg in your photographic bag.

I wonder at the wisdom of Sigma in designing a lens like this. Perhaps it would be more interesting if Sigma had designed a 50-300mm F3.5 lens for M43. I believe it is technically possible to build a professional lens with those specs, but that does not weigh much more than 1kg. Such a lens could be used handheld by most photographers. It would be a winner.

I guess you haven't done much of hand-held bird photography? For example, when shooting form a car 2-3kg is not too heavy, and this weight can even be used hand-held for quite a while if you are used to it. On the other hand, a 50-300mm for birding would be simply too short, unless you live on the Galapagos Islands, or maybe in Costa Rica.

In reply to:

DrLogic: No stabilization for Sony? The extra reach is useless without stabilization... And this is a very large range kit lens - the single IQ compromise range somebody takes on a holiday to replace a whole a whole bunch of lenses, so they aren't likely to be using a tripod. Doesn't make sense.

Tamron and Sigma have been doing this for a long time... since they sell less items for Sony and Pentax mounts, it must be cheaper for them to make a second version without OIS.

jamesbm: Hi - is the Contemporary version available in Sony FE or A-mount - the article seems to contradict itself? Thanks

Looks like FE mount only for the near future... but you're right, it could be both too, since they are announcing the lack of OIS for Sony.

Does make sense for Sony A-mount cameras, since they have sensor stabilization. Maybe for Sony E-mout they will leave the OS in...

That's why they also offer a second, lighter version...
