    Well, maybe someone can tell me what I'm missing. With no af and that kind of money, I thought this would be a niche product for those who absolutely must have the best iq possible. But since the iq seems to fall short of the much cheaper canon f 1.8, I've gotta wonder what the point is. Are there people out there that are willing to buy a lens based on build quality alone? Or the zeiss name?


    All that aside, thanks for the review, Bryan. Now I don't have to lust after this particular lens. (And can instead continue lusting after the canon f/1.2 )

    "IQ" means different things to different people. You and I care more about resolution and contrast, but someone else may place more importance on the bokeh. The undercorrected spherical aberration on this lens makes the bokeh very different (and attractive) compared to lenses that are well corrected.


    Also, for some users, such as 5D2 video shooters, the manual focus features are vital: "The 270°-rotating manual focus ring is wide (covering most of the lens barrel), very smooth and very precise.
    There is no play whatsoever.
    Again, there is no rubber on this ring - it is all metal.
    Engraved distance markings on the MF ring are accurate and line up with the engraved DOF markings."


    Cine lenses cost ten times their still-lens brethren just to have manual-focus related features such as precise markings, long throw ring, reduced breathing, etc.

    Thanks, Daniel. I can understand the point of view that bokeh is as or more important than resolution... after all, you don't have to be a pixel peeper to tell good bokeh from bad. The difference can show up in modest sized prints.


    Do you have samples, or know where I can see samples, of bokeh such as you describe, ie, an undercorrected lens producing more pleasing, or at least very different, bokeh from "well corrected" one? My idea of good bokeh is what is produced by canon lenses that are held in high regard in this aspect: ie, 100mm macro or 70-200 f/2.8 IS. I'm assuming these are not undercorrected, so maybe I've never seen really good bokeh.


    I can also understand how for cinema, you would want better manual focus control (and manual aperture control as well, I suppose). Of course the problem with the 5D II is that in video mode, one can't judge focus accurately enough for it to matter how good the focus ring is. At least I can't.

    I'm absolutely sure I'll save up an extra $700 for the 85L II when I'm ready to purchase this focal length, which I am heavily considering.

    I don't have samples, but you might have some luck with a few google or flickr searches. Well corrected SA gives out of focus specular highlights that are even in intensity throughout the range and look great. Overcorrected SA which gives bokeh a bright edge, with a harsh look to backgrounds. Undercorrected SA causes the edge to fade out, which is the pleasing quality that lens designers will trade resolution and contrast to attain. The worst SA is when it's a complex curve.

    I think those have very good bokeh, I sure the 100mm macro is well corrected, but I don't know about the 70-200. (I have f/4 and it is definitely not undercorrected. The bokeh is still great, of course.) The 200mm f/2 IS is undercorrected, for example.

    It's tough. I'm able to focus very well in locked off shots with 10X magnification, but in dynamic scenes or handheld it's much harder to get critical focus. I think I can do well enough for at least 720p though.

    looks like a rather underwhelming product.. i was initially excited about it, to the end that i would have been willing to put up with the MF, as it looked like a pretty good portrait lens.. not now! if i'm gonna spend that much on a lens, why not spent the extra few hundred and go with the canon 85mm f/1.2?

    Interesting, but confusing.


    I don't know anything about how lenses work, but I thought an undercorrected lens sacrifices in-focus image (and foreground bokeh) for background bokeh (so what you said about the zeiss made sense). Yet the 200 f/2 has a basically perfect in-focus image wide open. If it is undercorrected, what would the in-focus image look like if it was well corrected?


    I agree that one can get good focus with 10x magnification on still objects, and I find this the best way to focus on still objects (this is especially useful for astrophotography... at high iso I can see dim stars with live view). I usually start movies focusing manually in this way. The problems start when something decides to move

    Maybe I'm wrong. My information came from an astrophotographer on Cloudy Nights; he said that the 500mm f/4 IS and 600mm f/4 IS were well corrected (and therefore highly suited to astrophotography), while the 200mm f/2 was undercorrected for bokeh.

    <p style="margin: 0cm 0cm 10pt;" class="MsoNormal"]<span style="font-size: small; font-family: Arial;"]Bryan,
    <p style="margin: 0cm 0cm 10pt;" class="MsoNormal"]<span style="font-size: small; font-family: Arial;"]Thanks for a great review![]
    <p style="margin: 0cm 0cm 10pt;" class="MsoNormal"]<span style="font-size: small; font-family: Arial;"]The Zeiss 85/1.4 was once my most anticipated lens with great expectations. I personally don&rsquo;t mind a full manual lens that maximizes manual experience as long as the image quality is top of the line. To be specific, I was expecting the Zeiss to at least match up the performance of the Canon 85/1.2L II at identical apertures (although nothing can get too much better than the Canon); but now it seems that the Zeiss is a bit behind (overall performance). I have heard tons of discussion around the internet about the Zeiss lens, some of them are quite good and some of them are negative &ndash; that in the end brings me here to listen to you and play around with the ISO12233 charts. This certainly helps me greatly in understanding such a lens, I will thank again for the help!
    <p style="margin: 0cm 0cm 10pt;" class="MsoNormal"]<span style="font-size: small; font-family: Arial;"]So my decision, I think I will save the money for the Canon 85/1.2L, its optical quality is worth the $700 extra &ndash; I do portrait and some time it&rsquo;s in the evening or indoor. However, I do hope Canon to change the focusing mechanism of the 85/1.2, I actually tried this lens already in person before and I dislike (sorry to say) the focus-by-wire system and the extension of the lens barrel. Well, since I have the 85/1.8 for now I think I&rsquo;ll keep watching for a while.
    <p style="margin: 0cm 0cm 10pt;" class="MsoNormal"]<span style="font-size: small; font-family: Arial;"]All the very best!
