BBQue: What is the MFD of the 100-400 lens? In your previous news release you stated this as 0.16m (which would be fantastic), now it has changed to 1.8m in the description of image 13 above? So which is it?

The metric system seems to have you confused , they quoted 160cmm! add a zero and you have 1600mm or 1.6metres.

Where's the XQD slot? I currently have 2 different readers for XQD amd compact flash/Sd. It would be good to have only one.

how about a new sensor for those unhappy with a cosmetic makeover of a current line up of bodies and lenses. http://thenewcamera.com/nikon-patent-bsi-cmos-sensor-with-dual-pixel-af/ Nikon has always given special editions for anniversaries, generally with a little more bling.

QuarryCat: good close-up capability?
Sigma is trying to fool us...
It reaches 1:3.7 at only 0.16m - Canon reaches 1:3.2 at 0.98m
so nobody beats Canon with the really fantastic 5.6/100-400 mm L IS II

it is just a light and cheap version of a super-tele-lens - nothing really interesting.

Read the early threads, there is the confusion, I have just finished a referb on my house in the UK every single item I bought ,radiators , insulation, timber, screws kitchen units, electrical fittings , door's etc the dimensions are all quoted only in millimetres. The change has occurred and people havent noticed, it's now the standard. I you use industry and scientific measures its all in thousands, km, metre, millimeter, micron, nanometre,

As long as you are happy to live with the confusion, good for you.

Every engineering drawing the world over has a phrase somewhere on it "all dimensions in millimetres unless noted otherwise " or words to that intent, the confusion on this thread is a good example of why this is the standard.

Read the spec's 160cm or 1600mm or 1.6m, I wish they would quote figures in millimetres, industry works in mm's, cm's went out with feet and inches, decametres, hectametres, etc.

EXX: Why Sigma does not make a Sony A-mount and Pentax K-mount version of this (and some other recent ART lenses) is beyond me.

The flange focal distance of Sony A-mount and Pentax K-mount are shorter than the Nikon F-mount, so it is just a question of extending the lens size a little bit, together with the appropriate bayonet for the specific mount. No change in optical lens design required.

For Sony A-mount users, this lens would be a great modern alternative to the old Minolta AF 100-400mm F4.5-6.7 APO.

I enjoy shooting motorsport in the UK an attend the big meetings which draw a very large quantity of interchangeble lens camera users, probably 30-50% of attendees have a camera, and the vast majority use Nikon or Canon dslr , I rarely see a pentax, fuji Sony etc, at the F1 test day at Silverstone the average attendants are simply F1 fans and probably 60% of 4-5 thousand spectators had a Nikon or Canon dslr at least half of those had a 70-200mm lens or bigger. you will probably never see as large a group of photographers as at a top motor race. Sigma are making lenses for the majority. I realise this is just one example of camera use , but I would alseo expect the flight enthusiasts and wildlife shooters to be in the Nikon or Canon camp. I am not saying you cant use other makes effectively to shoot these events but producing mounts for other cameras may not be practical on quantity sold. plese note this applies mainly for long lenses, but how many have dual systems?

jor23: ok. with these big lenses, why not just buy a d810 and use Nikon lenses?

NIKON 85MM 80x73mm 350grams Sony 85mm 78x82mm 371grams, not much in it but Nikon wins on size weight and maybe cost

I would pair this with my 24-120 Nikon which also has the zoom at the front of the lens, looks like the zoom and focus rings also rotate in the same direction as Nikon, good for me.

In reply to:

deploylinux: I generally find no reason to buy lenses from anyone but Canon for my 80D, but Tamron is very tempting. Their SP primes and the new 10-24 aps-c lens especially. I'd like to see a comparison of the 10-24 versus Canon's EF-S 10-18.

I would like to see how it compares to all the currently available lenses in this class, most have been around for a long time and were tested on old bodies with around 10-16mp. It would be useful to see the best of the current crop retested along with this lens on the same body for a fair comparison.

In reply to:

maximme: can Tamron please do
a Pull-Push 200-500 mm
both Canon and Nikon has left a gapping hole

Push pulls are notorious for sucking in dust, which is probably why no one makes new versions.

FoxShutter: @Arastoo Vaziri, @Revenant
You are right. But its not a good marketing move or a promotion, IMHO. People with an old gear are not likely to upgrade later. People with a new gear, like me, won't be able to use it or even try. The result is that the app is in my recycling bin and my Lr CC and Ps are running on my screen at the moment. The next time I see a "promotion" from DXO, I won't even bother to read through.

Supports the D800 that I have and also the current D810, it's worth a try for me.

gakenstein: no support for D7000?

There is a similar sensor in the d3000 and d5000 perhaps it will support them? Costs nothing to download and try.

Hugo808: Changeable grips! Now there's another great idea from Pentax.

I think pentax were first with the film LX body from 1980
