Oldbike: At the end the day the day, the manufactures are the ones who benefit.

Do you think they have not been developing prototypes for many years , but simply do not think that the technology is not yet as good as a DSLR for focus.

cosmicnode: Why are people assuming that full frame mirrorless lenses are smaller. Simply look at the specs on Sony Nikon and Canon comparable lenses in most cases there is little difference in size, Sony has few wide angle primes, the smallest is the 35mm f2.8 which is only a few mm smaller than Nikons faster 35mm f2D lens, weight differences can be down to the construction and materials used, less material more plastic can account for this.

@T3 but the sizes of the lenses are all very similar, this is the point, you are not getting small full frame lenses which is the biggest claim of a smaller registration distance, compare a 17-35 f2.8 Nikon to the Sony 16-35 f2.8, not exactly the same focal range but close, Nikon is 82.5x106mm and 745g, the sony 89x122g and 680g they are very similar the Sony is bigger but slightly lighter. Differences are coming down to the types of materials used in the construction of the lenses and the optics. You can cherry pick different combinations of lenses and bodies to prove points but overall there is little difference, if you use a adaptor you need to add between 100 and 250 grams to the pairing

Vincent in Geneva: Moreover, my old Nikon glass is more compatible (with adapter) with my mirrorless Olympus (which measures exposure), than with recent Nikon DSLR's (3xxx to 5xxx) which don't.... And once you've bought into a new 35-50-80 set of primes, you're basically done with your previous mount. Thought I would use my Nikon lenses a lot, but eventually crossed to MFT quickly and with no regret considering the smaller size ...buzz buzz... as Thom would say ;-)

The 35-50-80 mm set of primes are a poor example of weight and size saving they would need to be longer than the current lenses to make up for the loss of flange registration distance. Sony 35mm f1.4 is larger and heavier than the Nikon, Nikon has a 35mm f1.8, Sony has a 35mm f2.8 so no comparison. the Nikon and Sony 50mm f1.8 weigh the same, the Sony is longer, at 85mm f1.8 the Sony is slightly larger and heavier. Only a very few wide angle lenses around 28mm and smaller would benifit from the smaller registration distance, maybe 5-6 lenses if we are generous. The new 12-24 Sony is only f4 and is not a lot smaller than the faster Nikon 14-24.

There are many people here who want Nikon and Canon to produce a small EVIL camera body for a new range of small slow wide angle lenses. probably around 5-6 lenses will be smaller depending on choice, the majority of them have never owned or wanted a Nikon or Canon, for various reasons , "I like Fuji Colour" "my m4/3 is as good as a full frame", "my smaller format lenses are smaller and give better reach" and many other very relavent reasons for not buying. They will never buy a small evil Nikon or Canon body but are telling Nikon and Canon users who also will not buy a small evil body that they need one. There are obviously some who will, but look at the "users forums" the majority are in favour of the current mounts, and the arguments are with a minority, or non users who want a new mount. Mirrorless cameras are not cheaper but more expensive than the equivalent DSLR despite the need for fewer componants and assembly being more automated,

4thnebula: A serious concern I have been having with the Sony mount is that it is too narrow since it was made for APS-C (NEX) and fitted to FF. I am hoping Canon knows what it is doing and goes the EF mount route for their FF mirrorless. I do notice that their current Dual Pixel PDAF is very accurate and has gotten significantly faster. I expect they are going the EF mount route and gradually merge to mirrorless.

@John C Tharp you can fit a Nikon lens to Sony Mount onto a Nikon Body, so they are also a similar size

stratplaya: Smaller isn't always better. I'm a man with medium/large size hands. The grip on my DSLR proves to be a very comfortable and secure point of contact for hours at a time. If Nikon/Canon do go down the mirrorless route I hope they don't geld the grip to where you just end up leaving the camera around your neck or hanging off your shoulder.

But the added grip does not change the original grips shape or size on the body to make it more ergonomically comfortable or move any of the controls for larger than small hands

In reply to:

mosc: OSDPDAF should make old lenses an adapter away from as relevant as they ever were. Isn't that obvious to all? You release a body, bundle in a physical adapter if you must, and let the sensor do the work the AF module used to and be done with it.

Lens isn't built with contrast AF in mind? Why is this relevant when both solutions support PDAF. In fact, on sensor PDAF aught to offer a much more sophisticated solution.

This could be the reason Nikon and Canon haven't rushed into mirrorless, they are probably solving this problem as we speak, they will make PDAF accurate then current lenses will work properly with or without an adaptor,

1Dx4me: while some of these photos look decent, for average joe there is nothing like personal experience with a lens out there on the filed! majority of the owners will be using 1.4x extender with this lens and make it turn into mush ;-) no comparison to canon equivalent, although canon is a lot more expensive!

Sometimes it's irrelevant whether one is better than the other, if you need more reach using a tc is a good way to get it , and you can still crop for even more reach if needed. If you simply crop you need to crop more without a tc. But it's better to have a zoom with the right range in the first place to not need to crop or use a tc.

Bambi24: Make a crop version of this lens, thanks Sigma.

Why would they do that? It wouldn't be any smaller or lighter. On top of that what size crop Dx, m4/3 or 1"?

I don't think anyone can say what the majority of users would do, I for one would not use a TC, it's to slow to start with

Magnar W: A lens for wildlife photography, and the fastest action captured is a turtle! :-)

For such lenses, tracking fast moving subjects should be the proof of how useful the actual lens is. I know tracking accuracy has to to with the camera too, but the lens itself plays a major role. Hope such pictures will follow when you add more to the gallery.

Action shots I can relate to, nice, Thruxton.

CaPi: Uncanny.. I actually hadnt thought of reassigning the video button,.. nice one for me!
just goes to show that there are nice fearures hidden or lost from memory in gear you thought you knew. More value for stuff you already have.
#fightgearaddiction ;)

It's a shame they took away the mode button to do it though. I don't use the video functions I really don't have any interest in video so I dont understand why the shutter release doesn't stop and start video. If a second button is required put this into the options of one of the function buttons.

@arniebook the D800 has mode, record and exposure compensation buttons. D500 has record, iso and exposure compensation buttons . On my D500 I have changed record to mode, and on D800 record to iso so I have a similar layout on both bodies.

Well behind, my D2h has 3 of those 7 features from 2003.

MShot: You can do it in an EVF if your camera has one. Most of this has been available in mirrorless cameras for at least 5 years. Good stuff, not much new about it.

It's not new stuff it's also been around on Nikon's for over 5 years to , he's just explaining some items which users may not know about, I have been using some of these features since I bought a D800.

stefdnk1: I have been wondering why of all these Professional reviewers at the Sony event not a single of them brought a grey card?
And why did Sony not invite any sports shooters in.
I admit I haven' read and seen all the reviews 😌

Living in the UK there are 100's of football matches each Saturday, all covered for local and National papers. Ignoring other sports thats a lot of sports shooters, add Motorsports, athletics, swimming etc, quite a lot. This is just one country, but dont forget amateurs who also want to use the most suitable gear, because they love their sports and you have a lot of users. Cant forget the rest of the world either, there may be one or 2 more there.

In reply to:

Mr Kobayashi: So Canon doesn't take any hits for topping out in size and weight in the comparison chart, because DPR doesn't compare these things...

I get that, but unless the ergonomics are life-changing, I've never heard somebody say "jeez, I woulda liked this camera if only it was bigger and heavier!"

Thing is if you do have large hands you will want it bigger, not heavier. its uncomfortable to hold a small camera no matter how light with your fingertips. Extra battery packs only add depth they do not increase the diameter of the hand grip area or repositiion the controls into a more comfortable position.

Why not just simply put a bubble level on top?

In reply to:

onlooker: Now just put in an EVF, 4K video with decent codecs, IBIS, and it would be close to a 100 for many buyers.

Ibis has no effect at all to the image in the viewfinder of a dslr. If a dslr has ibis the viewfinder image would be the same wether it was turned off or on. How you hold and use your camera on a dslr is what moves the image in the viewfinder, there is no connection between sensor and viewfinder image since there is no evf involved. Simple.
