George Veltchev: Some manufacturers like Canon can offers precision Matte Focusing Screens which are almost useless for general use but a must have option for those who use their lenses manually .... like in this case with the latest offer from Zeiss. So the lack of manual focus in most wide angle lenses is understandable, mostly because even wide open those lenses produces very wide depth of field, so as the working distances for most of the macro lenses can allows for a precise manual focusing. Once you have a portrait lens and a subject in a distance of more than few meters, then the manual focusing can become a real challenge for many, except if you have installed one of those precision Matte Focusing Screens . I have no doubt that the latest Carl Zeiss Apo Sonnar T* 2/135 is a magnificent lens, but the lack of Auto Focus can be a major drawback ...

I think based on how high performance typical 135mm F/2.0 lens are we can assume it will be magnificent if not near magnificent. It seems to be a focal length and aperture that is commonly the sharpest of lens available. Canons, Nikons, Sonys(F/1.8) lens are all blisteringly sharp lens.

How is it Sony hasn't been able to make a lens like this for the NEX system. This is basically a perfect mirrorless lens. great aperture and focal range, but not so overboard in pro-ness that it's unaffordable. Fuji is really making some smart decisions lately.

The problem with distortion is when you have subjects in the frame at different distances. If you have someone standing near the camera and someone 10 feet back, there really isn't a way to truly fix the perspective issue, the person near the camera is still going to be vastly larger than the person away.

Basically I want a version of this that also incorporates magic, giving me the perspective of a longer focal length with the framing and camera positioning necessitating a ultra wide.

Man I want one, I have a Panasonic GF2 which has the same sensor as the GF3 and the image quality is seriously sub par. If I could get a camera that is just a little bit bigger but has the image quality of a Canon DSLR PLUS auto focuses my DSLR lens. Very interested, will start saving.

Plastek: Well, so now those who waited for Canon mirrorless system know that they should have bought NEX instead.

Pity - huge chance wasted. NEX got by far more features, better bodies, real system with selection of lenses, bodies from very entry level to professional and selection of accessories. Canon got what? 2 lenses 1 body and 1 dedicated flash. Back in the day years ago NEX STARTED with wider selection and more adult system - now it's completely different league, especially because Sony's bayonet is open so anyone can build fully compatible lenses unlike in EOS-M.

I also thought that Canon will become a real competition to NEX and m4/3 but so far it only become a danger to Nikon 1 which was fail ever since release (big bodies, high price, no accessories, and tiny, worthless sensor that you can find in compact point and shoot instead of bothering with mirrorless system) and ever since haven't changed at all (no new lenses, no new bodies, seems to be close to well-deserved death).

The NEX lens selection is terrible. These two lens Canon is launching with are more appropriate to the form factor. Sony has no good pancake, they have that weird 16mm F2.8, this is way more functional.

Considering how long NEX has been out I think their lens selection is truly bad, samsung even has a better lens lineup for their system.

This camera is compatible with the Canon EF lens catalogue, the most mature and fully featured optical system on the planet. Lens are the one thing Canon dominates everyone else on, i don't know how you can say how that's a negative.

WASBA: Not good another big company's movement. If there is same mount as EF-S, this will be much better but EF-M and Adapter system? They are thinking people will buy this camera to use their many EF lenses with adapter. My personal concern is...
1. New Mount EF-M, 22mm f2 and 18-55 bundle are only supported lenses for this body without adapter. I know adapter system has lots of issue so far.
2. Point and shoot looking mirrorless camera? Love om-d or nex7.
3. Overall, There is no reason to change current my micro 3/4 or nex ones.

The OM-D and NEX7 cost double what this costs.

The white one is sexy. It's all about the autofocus though, if it's not faster than something like the Fuji x-pro1 I couldn't justify it. That sensor would offer better image quality than every m4/3(excluding OM-D) camera.

Everdog: bradleyg5, nice try.
The E-M5 runs circles around the old T2i. I can say this since I have used both. Also, the Olympus 75mm clearly performs better than the Canon 85mm lens (one of my favorite Canon lenses). The Canon also suffers from some pretty bad CA wide open, but still a good lens for the price...just not as good as the Olympus it seems.

Please message me to apologize when DXOmark gets around to testing the E-M5 and shows conclusively that it does not match the Rebel T2i. Ignorance is bliss as it were, but your bliss is finite.

bradleyg5: I could get a Rebel T2i and a 85mm F1.8 combined for 939 dollars(to this at 900$)... plus the rebel would give a slightly more usable effective 136mm focal length. Doesn't make sense to me, all 85mm F/1.8 lens are great, especially in the centre 1/4 of the image circle. Olympus puts a metal casing on it and expects more than double the going rate...

Just backing up my 2nd point about the lens, here is proof that pretty conclusively shows my point.

From a more reputable lens reviewer Photozone.

The 85mm F/1.8 scores a little less than 1850 line widths per picture height (LW/PH) when mounted on a 8MP canon 350d http://www.photozone.de/canon-eos/164-canon-ef-85mm-f18-usm-test-report--review?start=1

The 85mm F/1.8 scores a little less than 2280 LW/PH when mounted on a 15MP eos 50D http://www.photozone.de/canon-eos/421-canon_85_18_50d?start=1

This completely backs up my statement that that resolution measurements tend to increase drastically as the pixel density of the camera sensor itself increases. Showing that the Micro four lens are a lot less impressive than those graphs on slrgear would have you believe.

Firstly it's worth noting that according to the DXOmark sensor rating, the Rebel T2i has a superior sensor to any ever made for micro four thirds.(by a over 10 points) So I believe Canon would be the porsche and micro four thirds the Camry.

Secondly comparing lens @Julian_K Two things, first you can only compare the very centre of the canon graph because the "soft corners" would be cropped off entirely when mounted on a Micro four thirds camera.

2nd point @Julian_K they did those measurements on a Canon 20d which has a 8MP sensor on a 1.6x crop. They did the 75mm measurements on a Olympus EP-1 which has 12 megapixels crammed into a smaller sensor. Put both lens on the EP-1 and then get back to me, I would wager they are virtually identical on the same camera.

In reply to:

marike6: Interesting lens. But this begs the question, why not just use a 50 1.8 or faster short prime? As someone pointed out, the lightest FF is 950g, is a slightly larger lens going to make much difference in usability?

I think it's that the pancake doesn't stick out much past the grip. So if you have a lens that's twice as long it actually sticks out significantly more past the grip. The 50mm f1.8 isn't really usable till F2.8 anyway so the speed advantage isn't an issue.

It's about fitting your camera in a small bag that isn't triangle shaped, you could fit this in a bag that is normally intended only for the camera body.

What's the point of having a smart phone if you don't have access to a large application library? I feel like it would be an extremely frustrating experience moving over from the Apple platform onto one so limited. Want it, but could never live with it.

I have a 5dII and I'm going to pick up the 40mm pancake as soon as I can, 200 dollars is a buy. Even the 50mm F1.8 is just a little to big to fix into a small bag.

I'd like to be able to take my camera to more public spaces, but if I end up not using it, not have to lug around something large and inconvenient.

Hopefully that stepper motor will help it perform above average with live view focus even on the 5dII. The 5dII is very silent when taking pictures in live view, but the problem is always getting it focused.

I want something more inconspicuous and quiet but am not willing to invest in micro 4/3 given their very aggressive lens pricing, this lens is a great way to adapt what I already have. Obviously I'd prefer to have a Panasonic Gx1 and a 20mm F1.7 but that's a thousand plus dollar investment which is not practical when I already own a two thousand dollar camera.

In reply to:

micksh6: Front element seems to be rather large. 75mm F1.8 lens requires only 42mm front element diameter. This looks close to 50mm probably?

For comparison, Pentax 77mm F1.8 limited lens has 49mm filter thread and its front element is smaller, probably around 43mm.

I wonder why is that. Maybe this lens is a bit faster than F1.8?

I would wager the design is very close to a typical 85mm F1.8 full format lens. It's probably over designed in that respect because you end up with less vignetting and greater sharpness when you are just using the centre of a larger image circle.

justinintokyo: Most sources are reporting $799 but either way, well worth the money. Can't wait.

@DarkShift
Make sure when you compare it against the Canon lens you only compare a 1/4th image crop of the very center.

Direct link | Posted on May 24, 2012 at 06:47 UTC

This is getting absurd dpreview you should be ashamed.

This listing the focal length "equivalence" right next to unadjusted aperture is border line disingenuous.

It is not a f1.8 150mm "equivalent" lens, it is and forever will be a 75mm lens, it doesn't magically become a 150mm lens just because you put it on a camera with a small sensor.

If you insist on listing "equivalent" figures, list the equivalent aperture right next to it so people don't get the wrong impression.

This lens at f1.8 75mm will produce an image on a micro four thirds camera that will look identical to a F3.5 150mm on a full frame camera, for you to imply it will look like f1.8 150mm is flat out wrong and shameful.
