Brian Sweeney Writes About the Nikon Df - and Buys One!

Nikon Df

Brian Sweeney is a Leica and Nikon photographer whose name is pretty well-known on the photography forums. I've written in the past about Brian's work with vintage lenses, namely the Zeiss Sonnar, on Leica rangefinders.

It seems that Brian was won over by the new Nikon Df DSLR, which is modeled after Nikon film SLRs of the past, sports an ideal (in my opinion) sensor size and resolution for low noise and high quality image performance, and even allows us luddites to use our oldest pre-Ai Nikon lenses.

Brian believes that the Df is for Nikon what the M-E (M9) and M Monochrom are for Leica - real, practical digital answers to their excellent film cameras of the past.

 

Brian takes us through the evolution of his perfect kit (for personal work that is; Brian has used digital for professional work since 1993) in three major steps:

 

1. Originally, his chosen camera bodies were a Nikon F2AS (SLR) and Nikon SP (rangefinder).
2. Then, the Leica M9 replaced the SP for him.
3. Now, Brian's chosen kit is a Nikon Df (SLR), Leica M9 (rangefinder, for color work) and Leica M Monochrom (rangefinder, for black and white work).

In his post on THEME, Brian shares an image shot with the Df at an incredible iso setting of 20,000. Of course, it's impossible to evaluate how that image would look printed, but on the screen it sure looks fine. Not even nearly possible with the venerable film cameras.

 

Having Brian buy into the Df is an influential factor for me. Until now, he's been unconvinced by any potential digital replacement for his F2. That's a long time waiting. There must be something to this Df thing.

 

I still am in love with my Nikon F2. I'm still in love with my Leica film cameras, even though I own and enjoy the digital Leica M9. My current problem is one of too much gear and not enough time to shoot. But, I did get to handle a Df at McClanahan's Camera in Warrenton, Virginia recently. I cannot say that the camera hasn't been on my mind ever since...

Brian Sweeney Writes About Using the Old Zeiss Sonnar and Leica Digital M on THEME

I love using classic lenses on my M9, as you will have seen by my "Whole Lotta Leica" series. I also love to learn more about these old lenses and how they are designed and perform.

 

Brian Sweeney has made a name for himself in adapting Zeiss Sonnar lenses to Leica M mount. Brian recently wrote a post for the blog THEME, describing a lot about lens design history, adapting Sonnars, and the resulting images.

Here are some new things I learned from Brian's post:

 

• Leitz (Leica) has taken the approach of minimizing aberrations in their lens designs, particularly through symmetric "double Gauss" optical arrangements. According to Brian, this is the approach used from the early days, up to and including the modern APO Summicron.
• The concept of double configurations is that the front lens assembly's aberrations are cancelled out by the light going through a paired optical assembly at the rear.
• Asymmetric designs allow for wider apertures.
• Zeiss has usually pursued brighter lenses and higher contrast than Leitz. They achieve this through asymmetric design and minimizing the number of lens interfaces and gaps. For example, the classic 5.0 cm f2 Sonnar has 6 gaps, as compared to the similar era Leica Xenon, which has 10.
• Zeiss Sonnars in original Leica mount are very rare. As a result, Brian has found ways to remount them from other mounts, like the much more prevalent Contax mount. In the post, he even shares a link to instructions to try it yourself.

In Mr. Sweeney's examples, I can see what he describes about the different rendering of the Sonnar. While very sharp, these older lenses, many uncoated, don't have the contrast of a modern lens. While lower in contrast than modern examples, they are described as being higher contrast than older uncoated Leitz lenses, like the Summar.

 

I have a couple of uncoated Leica lenses - a Summar and a Summitar. Both are favorites of mine. I don't have a classic Sonnar, but I do have the modern example of the Zeiss C-Sonnar 50mm f1.5. It's an amazing lens - both loved and hated strongly by different photographers. I love mine. In fact, I think it will be my Whole Lotta Leica lens for June.

 

Here's an example shot from my modern Sonnar on the M9.

If I were to pursue a classic Sonnar for my Leica, I would try to buy one from Brian. They come up every once in a while on the forums.
