Battle of the best 20/21s: Sigma 20/1.4 Art vs Zeiss 2.8/21 Loxia

20 art 21 loxia
Images courtesy respective manufacturers, composited to roughly correct relative size – my samples had to return home before I got a chance to put them together in the studio for th usual product shoot, and I’m still awaiting delivery of my own personal lenses.

I’ve recently had a chance to shoot a) the best two wide angles available at the moment, and b) shoot them against each other on the same camera body. This is not a direct comparison. There are however limitations to the testing – very limited time* and no way to mount one without. Furthermore, the lenses were both final preproduction prototypes, which could mean they are either good samples because they’re hand adjusted…or there’s some variance, because…they’re hand adjusted. Tests were performed on a Sony A7RII body mounted on a Arca-Swiss P0 head and RRS24L tripod – i.e. sturdy – and released via IR remote. The adaptor used was a Metabones Nikon G-NEX model, tested and found to be good with various other lenses including the Zeiss 28 Otus. However, it’s worth noting that the shorter the focal length, the more sensitive a lens is to small skew because only very small movements are needed to change effective focusing distance. I’m sure many other limitations in methodology can be found, but remember we are aiming for the best we can do in field conditions without giving one lens or the other a sensor-based advantage. Observations must therefore be taken as preliminary.

A guide to Zeiss lens choices for Sony FE

_SL1000534 copy

The challenge we have now is no longer one of insufficient lenses: it’s almost one of too many. Having spent the last few months navigating the options and trying to figure out which of them work best for me, I now feel qualified to write this post which will a) explain the differences, b) make some recommendations both for the various series of lenses and within them as a whole. It’s worth noting that these comments and lens options apply to mirrorless cameras in general, though I’ve chosen Sony FE specifically because a) I own the A7RII, and b) there are several ‘native mount’ options that are available for Sony that aren’t for other systems – the first three on the list for starters, and won’t adapt because they require electronics*. I do honestly wish they’d thought out some of the naming better, though – it just lands up being both confusing for photographers and a bit of nightmare for their marketing team.

Premiere and review: The 2015 Leica SL (Typ 601) and lenses

_7R2_DSC3092 copy
Minimalist Leica with a hint of several other cameras’ DNA. Doesn’t look that big, does it?

What would you get if you crossed a Q with a T and an S?

Not an unpronounceable algorithm for a consulting firm or a new Cadillac, but the 2015 Leica SL Typ 601. The SL is probably closest to an S (S Light?) and really does blend the choice bits of the DNA from each these three cameras into something that takes the fight to the Japanese brands – albeit with a few caveats.

Notes: I’ve had a few days with a final pre production SL and 24-90 thanks to Leica Asia Pacific, which is enough to form some preliminary impressions but further testing of a production sample will be required to evaluate all elements of the performance envelope. Sean Reid also has additional testing. More images from me with the camera can be found in this flickr set, and you may recognise some images from the Paradise Lost series. Images were processed using Photoshop Workflow II and The Monochrome Masterclass.

Review: the Zeiss 1.4/28 Otus APO-Distagon

_7R2_DSC3041 copy

28, 55, 85. A pretty versatile core set for pretty much any purposes. And now fully filled out by the latest in the Otus series, the recently-announced 1.4/28 APO-Distagon. Advance warning: this is not a general purpose lens, nor is it the kind of thing you can deploy casually. That is merely the nature of steeply diminishing returns; there are no gains without significant incremental effort. And we’re really talking about pushing the last 1% here. If you’ve not felt anything lacking in your images, then I suggest you stop reading here and save yourself a lot of money, because chasing perfection isn’t cheap…

News: Zeiss Otus 1.4/28 APO-Distagon, 2.8/21 Loxia, RX1RII, 19 October

Image courtesy Zeiss

The cover was lifted on the new Otus yesterday – a 28mm f1.4, as expected, and a 21mm f2.8 Loxia a couple of days earlier. The Otus is a 16/13 Distagon design and uses quite a large array of exotic glass and aspherical elements; it’s also quite large (95mm front thread) and has significant weight – but then again, what do you expect from an APO-designated f1.4 wide? From my experience with it so far, it is once again proving to be the reference lens in this focal length. Delivery is expected to be in 2Q 2016.

A visit to Zeiss and thoughts on the Milvus line

_Q116_L1030551 copy
The mothership

I was fortunate enough to spend the last three days at Zeiss with Lloyd Chambers (update: his blog entry is here) – with a level of access that I suspect that has never been granted before to independent external parties. They were gracious and first class hosts – I don’t think I’ve had that many types of non-alcohlic beer before. We asked every question we could think of and more, and received answers which we had never expected and at a level of depth that has left me deeply, deeply impressed with what the lens team is doing out in Oberkochen. This may seem like a strange way to talk about the new announcement, but bear with me for while; there is method to the madness. :)

Long term review: Canon 5DSR

_5R00808 copyWhen the stars (trees) line up

These will be my closing thoughts on the Canon 5DSR, first reviewed here. It turns out there won’t be a part two for a simple reason – I don’t see the point. My opinions that follow are going to appear initially conflicting and probably be misinterpreted by the fanboys, so I’m going to state this upfront: I really, really liked the camera. But in the end, it just isn’t for me. Allow me to explain why.

Review: The Canon 5DSR, part I – solo

_Q116_L1020283 copy

This is both the first extended review I’ve done in some time, and the first one of a Canon product. Regular readers will know that I only review things that are interesting, and to be interesting, they have to expand the envelope somehow. I am curious as to whether the 5DSR will do this –
I sold my 645Z a few months back because I could not justify ow ning a second system against the need for a larger home for my family; but I won’t deny that I missed its resolution and print flexibility, especially for making larger Ultraprints.

I come to this review as primarily a Nikon D810 shooter. I make no secret of the fact that I have not that much experience with Canon other than a serious evaluation period in 2007 where I decided if I should switch (pre D3); I didn’t because local support at the time left a lot to be desired. However, I also come to this review with an open mind: I’ve tried many other systems previously to expand my toolkit including Leica M, Pentax 645, Hasselblad V and M4/3. And I can guarantee you that I have no self-interest either way, since these experiments have come out of my own pocket. The 5DSR was also purchased at retail and is NOT a loaner. I don’t care what the name plate on my camera says: I care only that it lets me make the images I want to make and doesn’t get in the way, and my clients are the same. If anything, I am biased towards image quality. That said, I’m sure it’s only a matter of time before some forum keyboard warrior ‘expert’ asserts I’m now on the Canon payroll.

Note: I will present few full-size samples because I simply don’t have the bandwidth, nor do I trust that they won’t be reused without permission – it’s happened before. Given the limitations of web JPEGs, please go according to what I say and not what you see. Any perceived oversharpening is thanks to Flickr’s overzealous resizing algorithms and not blindness on my part. Read on if you have an open mind. Finally, a special thank you must go to my last client for allowing me to share some of the images from that assignment at the Crawick Multiverse and Garden of Cosmic Speculation. I literally collected the camera a few hours before heading to the airport and this was the first time I’d shot with it properly – no pressure…

Understanding AF and MF: focusing aids tested

_RX103_DSC0520 copy

Right after the question of ‘what X should I buy?’ comes ‘how do you manually focus your lenses?’ in popularity. Unfortunately, it’s not possible to dismiss everything under the sufficiency banner; contrary to the trends in image quality, we’ve gone the opposite direction away from sufficiency. There used to be a time when viewfinders were actually very good for acquiring focus manually; there was no choice because there was simply no other way to focus, either. That required a few things: firstly, a focusing screen with adequate coarseness (sometimes also referred to as ‘snap’); the same distance between flange and focusing screen and flange and imaging plane; adequate magnification, and fast lenses – to compensate for the coarseness of the focusing screen making it somewhat dark. Looking through the viewfinder of an F2 or a Hasselblad is a revelation compared to the drinking straws of modern finders. It seems we barely have the latter these days. So what can we do?
