Why anyone would name their lens after Rupert's squirrel is beyond me.
I can't believe how sharp this squirrel is, it must be a really good lens. I bet I could post a pixel peeper showing it is just as good as the Zeiss.



I am wondering… though what kind of lw/ph does this lens achieve compared to other lenses tested in the same lab? A test from one lab is pretty much useless, if you have nothing to compare it to, and lw/ph varies widely from test facility to test facility.

The Zeiss is 11P-MP sharper from wide open than Nikon's new 58mm. It's unfortunate that Dx0 doesn't display MTF results in lp/mm, but, non the less, one would have to agree that an apparent 11MP improvement in resolution is quite a remarkable achievement. I'm tempted to sell what's left of my Pentax rig as well as my Sigma 50mm for one of these but it might be prudent to see what Sigma comes up with in light of their recent releases.

Which lens did you use for that shot Norm?

Dpreveiw and DXo have their test for the lens out now:

Lens reviews update: test data for the Zeiss Otus 1.4/55: Digital Photography Review

The results are simply stunning; this might well be the sharpest fast 35mm (or at least non-rangefinder 35mm) lens ever made. The designers at Zeiss really deserve some real accolades for the sharpness and lateral CA control they were able to get with this lens (regardless of the price it ended up being). One wonders whether something else (spherical aberration, longitudinal CA) has not been corrected as well in order to get these results.
Very impressive indeed. Makes that lens very tempting...

More to the point, how could anyone confuse a squirrel with an owl?

OK, I've spent some time going through the whole Mpix thing at DxO, and as far as I can tell it's proprietary hooey. But, that's just a first impression. I really don't have time to investigate fully. Nor do I suspect it would be a worthwhile undertaking, simply because being proprietary, they aren't going to tell you how exactly it works and therefor, no one can check their results. Lw/ph, is really easy to understand, and you can look at the test images yourself and see if you come to the same conclusions. With DxO, I have no idea what they are doing. And no independent lab can confirm their results. They tell you what they think their results mean, and hope you'll take their word for it. Personally, I don't take anybody's word for anything. Especially not someone who is attempting to sell a product based on those results. It forces you to decide , snake oil salesman or scientific visionary. Most of us have met a lot more snake oil salesmen than scientific visionaries.

Can you tame an Otus Zeiss?

For the ones with an interest how the Zeiss Otus may perform in the field, I tried it after dark in the field:



The blog article has some more of my feelings when using it:
