Jogger: IT would be neat if Zeiss made an APO version of the OTUS 85/1.4 .. of course it would cost $8000.

It is APO as far as I remember.

On the topic of manual focusing. It is a different world focusing a lens such as the Nikon 50mm f1.2 compared to a well corrected lens. Even if you manage to focus the Nikon 50mm f1.2 (focus is done wide open) the focus will shift at f5.6. It will drive you nuts. When you use a well corrected lens such as the otus, you will see a sharp line from focus to out of focus. It is a different world. Also note, even after getting the Nikon D810 with is much improved live view, it is still very difficult to focus lenses that are not well corrected wide open. The sigma 50mm art on the other hand, is a beauty.

pictureAngst: Wow, just think how sharp all my cat pictures could be with this lens!

...although without autofocus, they would have to be sleeping cat pictures.

a cat is not a bad subject to test out the APO claim.

Joe Ogiba: The Samyang 85mm F1.4 costs less than the NJ 7% sales tax on this lens .

Im sure for the cost of a nice set of 86mm filters you could by the rest of the samyang lineup.

I compared the MTF charts from the older 85mm f1.4 to the Otus. It seems like the Otus has the same performance @f1.4 than the older design at f5.6. Zeiss also included MTF information at near and infinity focus.

Todays camera gear is very good. I would say most, 98%+ of "Professionals" are NOT limited by the gear but by skill. A small amount of photographers "2%" are so experienced and desire something closer to perfection. These photographers push the limits of todays optics. Zeiss is targeting the 2% and not the 98%. If you cant see why this lens is so special, you would not benefit from it. I always recommend the nikon f1.8's to anyone asking me for advice. If someone asks me if they should buy a zeiss, I tell them no because if they need to ask they would not get benefit from it (and possibly worse results than with a typical lens).

Gesture: Wished they had gone one step further and had a small LCD display where you go review the images and folders.

or maybe wifi to connect it to your phone.

BarnET2: Why on earth does Zeiss want $949,- on a simple 1920 based design
http://en.wikipedia.org/wiki/Double-Gauss_lens#mediaviewer/File:DoubleGauss1text.svg

The OPIC from taylor and obson from 1920 looks very similar.
So no R&D in lens design nor in mechanics since it has no AF nor IS.

I just can't fathom where the money has gone too here.

Lensrentals did some tests on sensor stacks and the thickness and how it relates to sharpness. Zeiss did compensate for the 2mm sensor glass stack on sony sensors.

If Ford made a model T replica today it would not cost $240 as it did in the early 1900's and it would be much better than the original given todays manufacturing technology. Price is also relative, im sure Madonnas used undies can go for quite a few $$$ on ebay. Price will be set according to demand.

These are classic designs with no aspherical elements. My guess is that it will have a very pleasing image, amazing bokeh but will not "rate" very well in the lab (at least wide open)

You know ZAnton, Im not even sure if olympus uses PDAF for anything but legacy 4/3 SLR lenses

I had so many cameras from olympus and panasonic it would be hard to list. E-P1 autofocus is very very slow. Lenses that came out around that time were also very slow. Use a current model with the current lens line and you will see how fast it is. Almost instant I would say.

You must been hiding under a rock for the last few years. Olympus and panasonic has contrast detection that is faster than 95% of ALL cameras.

CaPi: I am still unsure wether these two really can compare. What are we going for here? Will we learn if sensor size has become unimportant.?I wouldnt think so. hm. Any ideas?

1080p or "4K" is like making a small print (4x6 or 8x10). At smaller sizes, even cel phone pictures are hard to distinguish from Pro Cameras. Aside from sensor size, both of them are quite similar. Mirrorless, size/weight, features. If your looking for a still camera, these will work fine but many other cameras have better bang for the buck.

He did a great job with focus.

Sdaniella: so, the Sony A7S has video with Full M/M ISO (ExpSim LV) control like FF EOS LV Canons do, but Pany GH4 does not... ok, got it. Oly video is stuck in Auto-ev0/autogain LV (perfect, though for P&S videographers)

wait ... auto-iso isn't available ... hm, ok ESLV is available, but adjustable, but P&S autogain (auto-ev0) mode isn't available ... ok, now, I got it ... mimics most digicam autogain/auto-ev0 video modes, which lack full M/M ISO control ... how ironic.

btw, if you want on-the-go compensation adjustment of iso in M mode with auto-ISO, it's no different from making on-the-go adjustments with M ISO directly. in both cases you are bypassing auto-ev(pick your value) altogether anyway

Olympus GH4? ;)
