I would rather mount a native version either on a 5D3, it has a nice chunky grip, or on a D800. With the imperfection the adapter might introduce the Otus seems to be a waste for it's price anyway. If it has to be an adapted lens for the fun of it I would stick with the cheap stuff.If I sell everything else, I could scrounge it up. The A7r is USD2700, the LA-EA3 is USD200 and the Otus is USD4000
In Steve Huff's hands. He is using the Canon version with Metabones adapter.

Yup. for any pre-order of official stocks of A7 or A7r in Australia, you can claim a metabones adapter from Sony Australia. Quite a good deal if you need the adapter.

Sony OZ is a bit fishy: "Please note that all payments will be processed immediately, regardless of current product availability."
Don't forget it can take months to get the free goodies by post in Australia, usually they are really slow at procession the claims. From my experiences I had the impression they wait till all claims are in and weeks later they will order the stuff. Usually I had to wait half a year.

Hey. Thanks!!
Can get it faster from australia?

That's why I said that if I used it on the A7r, I'd get the A-mount version and the LA-EA3. I would hope that Sony would manufacture the adapter perfectly plus it would pass all the EXIF data. The D800 or 5D3 still adds another pound or so to the whole package and the 5D3's sensor may not equal the A7r and 22MP to boot. Since the Otus is supposed to resolve 50MP+, might as well get the sensor that resolves the most detail. Plus the A7r isn't that light so it might still be OK.
Just wondering how much better is this compared to the FE 55mm f1.8 ?
Esp no AF? Just interested to find out more.
Actually, ZoomZ, there's no need to retract because what you say is actually true.
When you have very thin DOF, it's quite hard to manual focus (Otus is MF only) on a magnified view using a Sony cam since the image is moving around in the viewfinder. OIS stabilizes the viewfinder when composing and helps manual focus. I face this all the time when trying to MF jumping spider eyes where with macro lenses at close distances, DOF is really really thin. At 55mm EFL, a shaky viewfinder would be less of an issue when composing, but I'm sure OIS would help.
Zeiss makes both and they say that the Otus is almost "perfect". They mention various lens corrections that help it at night where they say many lenses fail. Apparently "Otus" is some kind of owl with good night vision.

It would be still an adapter. I thought the article emphasizes on no matter how precise an adapter might be it will still be the weakest link. They tested already the highest quality adapters.
How many A-mount lenses offers Zeiss now directly? I doubt it's safe to say there will be an Otus for A-mount within the next decade and they won't release it with a glued on E-mount adapter either.

At close focusing distance IS is as helpful as no IS.
Depends on the lens. I use a 150mm Sigma OS macro lens, which is 225mm EFL, so its a macro lens, but you can be a little further away. It has an OS switch on the lens and is far easier to manual focus when OS is on. Here's a sample with that lens.

Cool, maybe I have to check out Sigma's offerings. The IS on the first party macro lenses I know is pretty useless at close focusing distances, the same goes for in-body IS.
I have the Sony LA-EA1 and LA-EA2 adapters. They seem to be perfect to me because Sony made them for their cameras. The LA-EA2 is a complex adapter, which has a pellicle mirror built in and makes the NEX series a SLT camera so it's really a module, like the Ricoh GXR modules.
I also have a variety of China made adapters and Kipons. They are all imperfect...
You're right that Zeiss has sold it's lenses through Sony, which has kept the price down because they are made in Japan. Lenses made in Germany tend to be much higher priced. Look at the Zeiss 15mm 2.8, which is made in Germany. It's 4x the price of the other Zeiss lenses made by Cosina in Japan. However there were rumours of an A-mount version. Perhaps it will come with AF
Thing is, if its made in Japan, will it be 1/3 the price and given it's complex design, will Cosina even be able to make it.

Yeah, I read the rumor but I doubt it very much. If Zeiss is going to market it themselves it will be an E-mount lens and because Zeiss wouldn't just use a SLR lens design with a fixed adapter it would be a different lens altogether. If Sony should do it I doubt this particular lens with AF has a high priority in their lineup. For A-mount they just released the still new 50/1.4 and for E-mount they have more important lenses to cover the next 3 years.
Seriously, if I would fancy the Otus I would go straight to the D800E.
But this prime is so big and heavy, I don't want either of them for private fun. The focal length isn't that handy anyway. I would prefer a 'relatively' small and light 40mm f/1.8 (something around that) with a max. magnification of about 0.67x (FF) instead.

I wasn't able to AF with the Sigma 150mm at that distance handheld or with monopod, but MF with focus peaking worked with the OS on. For normal shooting, I would say that the Sigma OS has about 3-4 stops effectiveness, but for macro shooting, its down to about 1 stop.
As for IBIS and AF, there is a wonderful solution in the OMD E-M5, 5-axis IBIS and 60mm macro lens. It's light and weathersealed, so I can carry it all day, rain or shine. 120mm EFL is sufficient and if you half press, you can get IBIS during composition. But most of all, AF works, even at 1:1 distances. It's the only macro combo I've tried that AF actually works handheld. My previous setup was Pentax K5/Tamron 90mm, and the Sony/Sigma 150mm.
I haven't had that much experience with the GX7, but on the only macro shoot I did with it, it seemed to work well with the Oly 60mm and it's lesser version of IBIS. Here's a shot and a link to a full resolution photo below. This was AF because I had to reach in through some other strands of grass very low to the ground.

Yeah. I've been debating buying the Sigma 35mm 1.4, which everyone raves about and it's "only" S$1K, but the thought of using it with my LA-EA2 put's me off especially when I am so happy with the output from my Zeiss Biogon 35mm F2 and it's so compact. The lure of playing with "perfect" kit... Sometimes we lose sight of photography...
Note however, that Zeiss is slapping the E-mount onto all their M-mount lenses, even though some are imperfect with the A7r, so there is hope for Otus. You might consider the 50mm Planar F2 when Zeiss put's the E-mount on that. Steve Huff said that it's extremely sharp with the A7r.
Haha, Macdonalds happy meal vouchers
I'm guessing probably some PWP promotions coming to Sony SG side. The free batt alone for HK Sony side makes its a superb deal already.
