    Here's a side-by-side that is ... kind of scary, huh?

    That is the TAMRON Adaptall2 MF 135mm f/2.5 alongside the SONY SAL-135F18Z ...



    It's like comparing a VW bug against a VW bus! Same image size, but entirely different IQ and sharpness. Honestly, you cannot make a silk purse out of a sow's ear.

    Things have certainly changed ... in the world of photography.

    Which one? The SONY ... no. The Carl Zeiss 135mm f/1.8 is fully AF and zeroes in on focus with high speed.

    Now, there is ANOTHER SONY 135mm ... it is f/2.8 and has STF built into it. It is Manual only and about $1200, to boot.

    It has dual aperture rings which actively soften the image edges providing a much smoother transition in bokeh.

    sorry, for some reason i assumed that zeiss lens' were MF. no idea where i got that idea from lol ...maybe cos when i was looking at the 85/1.4 zeiss it was only MF.

    the bokeh is interesting...reminds me of the nikkor 135/2 defocus control lens.

    Well, the SONY SAL-85F14Z - Carl Zeiss® Planar® T* 85mm f/1.4 is also AF. It has an "Auto Clutch", so that in auto-focus mode, the manual focus ring does not rotate - and in manual focusing, you’ll have a solid, hands-on feel.

    It also has a "Focus Hold" button, which is located on the lens and can lock auto-focusing even in continuous advance mode - and focus lock can also be set on the spot-focus center frame area.

    Is the one for Nikon not so equipped? That's novel.

    Personally, with what the TAMRON SP AF 90mm f/2.8 Di 1:1 MACRO delivers, I would be hard pressed to justify the $800 extra coin, unless I just need more gosh darn light and some seriously fast focus. The T90 ... is not the fastest to focus, but on A700, it does have good speed. Also, true MACRO is nice ... and at a distance of one-inch ... LOL ... truly hard to beat.

    Thumbs up After a few months ...

    I have to say, as a "night scope", the SONY CZ 135mm f/1.8 has been terrific. In fact, no other manufacturer has a lens this wide, this long.

    I had originally purchased it with the future purchase of an α900 in mind, but after using it for a number of months ... with it effectively acting like a 200mm f/1.8 on the A700, in comparison ... LOL ... why bother?

    Today is cloudy ... not very bright inside. Probably about the same light you would have with a 20 W bulb. LOL

    So ... I used the HIGH ISO noise settings, slapped the 135mm f/1.8 on ... and shot the target (distance = 10 feet). Other than resize, this is the shot.

    Now, to truly appreciate this ... you need to set your camera to these settings, turn off all the lights in the room and have daylight coming in through a 18x36 inch window, behind you ... 15 feet away from the subject.

    Here's the same shot, all AUTO and w/pop-up

    The Nikon versions of Zeiss lenses are made to Nikkor AI-S standards, which means they are manual focus only. It only makes sense that if Zeiss is directly supporting Sony with lens designs that they would have access to Sony's AF ability. I suspect that Sony is the only brand that will AF Zeiss lenses.

    the zeiss 135 does look nice. havent seen much great stuff come out with it, but thats cos so few people own it so its hard to find real world examples.

    droopy's 135/2L shots have been stunning though. really something. its one of the very few canon lens' i've not had the opportunity to use at all and i have to say i'm very impressed with what i see.
