The NEX is a very good camera to use with this lens. Do you have the CA control option enabled in your NEX? I find it amazing how well it works; it has made several of my lenses nearly perfect.


Aha, the CA... maybe. Sorry about my ignorance, but, what is that? Embarassed I use the focus peaking option but it works for me better the MF assist.

Pancolart, thanks for uploading my photos properly, as I'm having problems to insert them and don't know why.

Regards


Is it maybe a Color Aberration correction? I always use RAW files, so I think that doesn't affect, does it?


Chromatic aberration.

For example: When there is contrasting colour like a branch in front of the blue sky look for a bluish tinge along the edge of the tree branch.

Maybe if you don't know what it is, you aren't experiencing it, which suggests your camera has the option set to on. I don't recall where in the menu it is and I would have to search for it, but if you browse through the settings, you'll find it. I think it is on for raw as well, but can't be absolutely sure. I have tried to use raw and have done some reading about processing raw, but I can't get as good an image from raw as the jpg from the camera - with some minor Photoshop adjustments; mostly contrast.

FWIW, I have the lester dine kiron 105mm f2.8 macro lens and I have tested/used it at both infinity and macro ranges.
I found it to be very sharp, very little CA, and excellent contrast and flare resistance.

To my eyes the Zeiss has the slightly deeper color saturation specifically the blacks of the lens.
However the Tokina keeps up very well in the sharpness department.
The bokeh is nice in both.

Hi all, I've just come across this amazing lens through my cousin, who just picked one up for his Sony NEX. I'm just wondering if anyone can share their thoughts about the best adapter to get the lens working on a Canon 5D MKII?

Also, am I best picking up a non-Canon Tokina and adapting that? I've read about the issue of it not focusing to infinity, which doesn't bother me too much, but if that's the case, what would the (approx) maximum focus distance be?

Any help would be greatly appreciated. Thanks!

I haven't read through the hole thread so this might have been adressed already. I don't know where the "Bokina II" designation comes from. There is only one Bokina and that is the Tokina macro. The name naturally is derived from a combination of Tokina and bokeh. The kiron, vivitar etc are very nice lenses in their own regard but they are no Bokina.

Because the optical design of this lens was done for Vivitar, and Vivitar sold a version of this lens before Tokina did (although it was manufactured by Tokina) as the Vivitar Series One 90mm f2.5 Macro. They are the same optically, with just the usual cosmetic build differences, plus different lens coatings, and a slightly different shape to the aperture blades.

Yes, they may be the same in almost every regard but only the Tokina is the "Bokina". It's wordplay: Bokeh + Tokina = Bokina

does that make the Series 1 a Bokitar?

"Bokitar", that's actually a good one Very Happy

I'm still calling my Series 1 Bokitar from now on Cool
It has the same bokeh characteristics as the Tokina and should be recognised as such Wink

The only lens that can replace the bokina is Zuiko 90 2.0. No other lens will replace my bokina Smile
