Zeiss Otus - If you shoot on a 50mm lens on a regular basis you should look at this.

I was extolling the virtues of the new Carl Zeiss OTUS 55mm lens to a highly respected photographer friend.

'Stop right there I don't want to know about it' he said

'It's another expensive piece of equipment that I'm never going to own' was his justification.

In a way I know where he's coming from 

I'm a fan of BBC's Top Gear programme.

For all its laddish behaviour and sometimes boorish comments it is still highly entertaining.

Yet when I find them reviewing some highly highly expensive car like the special super super carbon fibre version of some Lamborghini or some other daft sounding Italian high-performance car I find myself glazing over and somewhat tuning out mentally, not because I don't like fast cars, indeed I love fast cars, it’s I knowing that it's irrelevant to me, I’m not going to own an £800,000 car anytime soon.

On the face of it a £3000+ standard lens is, well, rather extreme.

Unjustifiable perhaps?

Almost certainly.

Until you use one.

If you do you will see detail that simply does not exist on lenses made by Canon or Nikon.

Make no mistake the advantage the Otus possess compared to the camera manufacturers lenses is simply crushing.

Use the lens back to back and its like one of the lens is a lens and the other is doing an impression of a lens.

The advantage is most marked from F1.4 to F5.6 and wide open it is remarkable.

I did consider using a lens chart but I decided to leave that to the guys at DXO, who describe it as a ‘peerless prime’

 

I instead took it out on some real world shoots, working mostly at full aperture.

I compared the lens to  a Canon 50mm F1.4 and the bargain basement 50mm F1.8.

Why not the Canon 'L' series 50mm F1.2?

Simply because I do not own one.

I wanted one, then tried one and thought better of it, not being entirely convinced of its performance compared to its more affordable brothers.

All comparison images were shot on Canon 6d mounted on Gitzo 5 Series tripod with a Manfrotto 405 head, focused using live view to focus as precisely as possible, the Raw images were processed with the identical base settings in Capture One 7 and were treated identically.

Firstly full frame on the Otus at F1.4

For me this is perhaps the most impressive of all of the tests, a nice clean image shot at F1.6 on the Zeiss Otus.

And then you see the detail which in my view is truly remarkable.

And Finally the portrait session with Tony Benn

Just wonderful detail.

The images are far from a full test of the Otus, I would like to add some comparative images at other F-Stops, but as I said before, wide open is where the gulf is biggest.

The advantage is most marked from F1.4 to F5.6 and wide open it is remarkable.

Quite a lot has been written about the Otus in terms of its optical performance, but little has been written about its form factor.

If you are used to manufacturer 50mm prime lenses by the likes of Canon and Nikon you will be struck by its size and weight, which is reminiscent of a medium format prime lens.

Initially this could be seen as a disadvantage but in regular use I have found that the slightly longer barrel length and it's tapered shape brings ergonomic means it fits your hand perfectly, I reckon I can hold a slightly longer prime more steadily too(I wrote about this a couple of years ago)

If you have not used a Zeiss lens before the chances are that you will be struck by its build, fit and finish too, which shades camera manufacturer lenses.

Focusing with any fast prime wide open is problematic, with auto focus or not, and the Zeiss is manual focus only.

I was initially apprehensive about this but the longer throw on the focusing ring does make make manual focusing easier than you might imagine, the situation was further improved when I retro fitted the Canon EG-S focusing screen which is optimised for fast lenses making the images snap into focus much more easily than with the standard screen(I have written about this previously)

Is this a lens for everyone?

Clearly not, but it is a lens for the shooter who does not want to compromise on quality.

If the 50mm focal length is one you use regularly, and you want the very best imaginable quality then I suggest you try one out back to back with your existing lens, you may well be surprised.
