AstroStan: "without it, the overall market would have experienced a 2% decrease year"

That statement is unsupported by the actual data presented and almost certainly incorrect. Absent Sony, most of those sales likely would have gone to Canon, Nikon, etc.

@Eugene232: False. Zero full frame camera sales would have gone to Olympus, Panasonic, or Fuji as these brands do not have any full frame cameras for sale.

OhWeh: In two years Nikon will be number 4 behind Sony and Olympus. At all formats.

Olympus? Micro four thirds is dead...

Free Jazz: We'd better call the theory "equivalent total exposure", not "equivalent aperture".

even "len aperture diameter" or “pupil entrance” might be a way better name than "equivalent aperture".

"equivalent relative aperture" is correct: f-stops are relative aperture, relative to the focal length, so they should scale with the equivalence.

However, we'd better stop equating "aperture" to "light transmission", because they are not the same thing. Many fast M43 lenses transmit only a fraction of what they promise with their f-stop.

Olympus 25mm F1.2 --> T/1.8
PanaLeica 42.5mm F1.2 --> T/1.7

A lens has a light transmission (T-stop) projected onto a surface area. To get the total amount of light, one needs to integrate this transmission over the surface area.

RubberDials: So many moronic comments on this page - too big, too slow, overpriced, paying for the blue badge etc..

If only the lens designers at Zeiss knew as much as you guys eh? They could have made it smaller and a lot faster!

Why don't you try emailing them your lens schematics? Maybe chuck in some suggestions for where to use aspheres or air spaces and what kind of substrates they could go with. Ways they could polish the elements to cut down on light scatter...

I'm sure the guys at Zeiss/Tamron/Cosina or whoever throws this Zeiss junk together would be pleased to get your designs. They haven't got a clue, right?

Early indications are that the optical quality of this lens is astounding, but I'm sure you guys could do better.

Batis 18, 25, and 85 are all patented by Tamron. Google it.

" I prefer what Zeiss can produce, be it with the Loxia or Batis range."

So far all the Batis have been designed and produced by Tamron.

In reply to:

Dimijis: Can someone enlighten me as to why a manual lens that communicates EXIF data is such a big advantage ?
Will it make me better pictures ? will it get me more clients ? or make my life overall more fulfilled ?
Coz I would argue that a lens void of any electronics that can fail is more of an advantage.

Automatic magnification when focusing is a big plus. Communicating the focal length and focus distance also makes IBIS less tedious to configure.

In reply to:

Rod McD: Its a great pity Cosina don't offer them in other mirror-less mounts too. Why not Fuji, MFT and Canon M? Those of us who would like to use them will have to adapt the old Leica M mount lenses they already have out. For me personally the Apo Lanthar 65/2 is the most interesting of the three. I'm not sure if that will even be available in Leica M mount either.

These are full frame lenses. Canon, Fuji, MFT don't have full frame mirrorless. If anything, they could release them for the PanaLeica SL.

In reply to:

panchorancho: Why bother making these in E mount? I'd rather have them in Leica M mount that way you can adapt them to different cameras. Buying MF glass solely for a Sony body seems like a waste of money.

@villagranvicent: so then according to your logic why would anyone want to buy dedicated M-mount glass? Because if you buy Canon EF-mount lenses, then you can use it on your Canon DSLR, on your Sony A7, and on your Leica. Yeah, who is crazy enough to buy dedicated M-mount glass... makes no sense whatsoever.

iae aa eia: The 35mm would be better (would make more sense [to me]) if it were a 31 or 32mm, and the 40 were a 43.

In reply to:

Triplet Perar: As users stated below, something is odd; no true MF look to this. In one image only, like, there was a hint of it, vaguely, because of forced perspective, but overall all is boringly flat and two-dimensional. Don't know what they do exactly, but Hassy and Pentax seem to know how to make a proper digital MF camera, which deliver what is expected from the MF.
Thus far, this Fuji looks just like a giant point and shoot 50 megapickles camera.

That makes sense because the Fuji has the smallest possible MF sensor, only just slightly larger than 35mm full frame. It makes sense that the result is closer to any full frame camera than to a Pentax medium format camera.

In reply to:

villagranvicent: Seems Sony FE and Leica SL are competing to see which one has the bigger one.

How so? PanaLeica SL has a 90-280mm f/2.8-4. That lens is an automatic win.

EcoR1: Best part with this new Sigma is the fact that it truly reveals how much bigger, heavier and unbalanced it is compared to the mirrorless equivalent Sony 85 GM: http://camerasize.com/compact/#624.516,669.612,ha,t

"Are you comparing a f/1.8 lens to an f/1.4 lens?"

Seriously?

In reply to:

Karnem: I agree that an equivalent focal length on crop camera is 136mm, but an equivalent aperture should be not F2.2 as you have mentioned, but remains 1.4, or am I wrong? Thanks for clarification.

Equivalent aperture is indeed f/2.2. The lens has a maximum physical iris of 60mm = 85mm/1.4 = 136mm/2.2.

What doesn't change is the relative light gathering, which in case of the Sigma is T/1.7 regardless if it is a full frame or crop sensor.

In reply to:

unbelievable: This review shows exactly why - for me - the MFT system makes the most sense as a mirrorless camera system. The penalty of (slightly) reduced image quality is compensated big time by a tremendous increase in portability over APS-C and FF.
(I fully understand that other antropomorphic entities have a different set of priorities)

It is a scam. MFT lenses are not smaller than their FF equivalent counterparts. You think you get a smaller system, but you also get very slow lenses.

If you want high-quality glass there is no escape from the size:
- The Pany 12/1.4 (f/2.8 eq.) isn't smaller than the Batis 25/2
- The Oly 17/1.8 (f/3.6 eq.) isn't smaller than the Sony 35/2.8
- The Oly 25/1.2 (f/2.4 eq.) isn't smaller than the Sony 55/1.8
- The Pany 42.5/1.2 (f/2.4 eq.) isn't smaller than the Batis 85/1.8

FantasticMrFox: "The company is making big claims about bokeh ..."

They made pretty big claims about the other G-'Masters' too, and neither Photozone, nor Lensrentals were all too impressed with the reality.

Agreed. G-Master seems to be all about claiming.

I'm much more interested in the Batis and smaller Sony/Zeiss offerings. I think that's where the magic is happening.

Mike99999: Sub-$999 A7 with FE 28/2 - 50/1.8 - 85/1.8.

Should be enough to obliterate crop-mirrorless competitors I would say.

@badi "not cool looking" vs. "much nice looking"

There you have it, the Fuji/Olympus crowd... jewelry-as-a-camera.

In reply to:

CanonKen: Happy to see Sony cranking out more and more lenses, and not just a parade of bodies.

Agreed - and a budget 85 was needed - but I would appreciate it if Sony let the 10mm ~ 100mm focal range be for now, and focus on lenses > 100mm.

The system desperately needs:
- 135/2
- 200/2.8
- 300/4
- 400/5.6
- 100-400/5.6
- 200-400/4
- 200-500/5.6

In reply to:

TerrificShot Photography: The major problems with Sony Zeiss Lens products is that focusing system on moving object is too slow.

I do own an Sony A7R2 and Canon EF 85mm f/1.2L II USM Lens that I still use on my other Canon 5dM3 body.

If this 85mm F1.8 mid-telephoto prime lens performs as Canon EF 85mm f/1.2L II USM Lens, I will definitely give it a try knowing the price is $600 versus $1,800 Canon EF 85mm f/1.2L II USM Lens.

is there comparative review already out there between these 2 lenses?

Why are you comparing a budget 85mm to a Canon L lens?

That Canon is a dog to focus. You should have a look at the Batis 85 or potentially the 85 GM. They focus much, much faster.

Sutlore: I would be happier, if they announced FE35/1.8 or FE35/2.0 as well.
Just got FE90/2.8 last month, I do not think I need another one.

FE 90/2.8 is a gem.
