March 2013 - Back in February I had another opportunity in Hong Kong to compare quite a unique collection of superfast 35mm prime lenses that - attached to a NEX-7 - provide you an equivalent angle of view to a classical 50mm lens on full frame. Three of them start at an amazing aperture of about f/0.95 that compares in terms of depth of field (DOF) to 50mm f/1.4 on a fullframe sensor.
One of the candidates, the SLR Magic HyperPrime CINE 35mm T0.95 was compared already in December 2012 to a Voigtländer Nokton 35mm f/1.2 ASPH (version I) and an AF-S Nikkor 50mm f/1.4 G on full frame (the Nikon D800E) (here, in memory), thus triggering a discussion about onion rings ...
The shootout candidates (ordered by transmission / aperture):
- SLR Magic HyperPrime CINE 35mm T0.95
The final production version used in this comparison will start shipping in about May 2013 for an introductory price of US$ 1249. It is a very solid (about 800g) construction with 12 lens elements, circular aperture blades and an extractable lens hood. The aperture ring operates clickless and is calibrated in T-stops (a transmission of T0.95 usually requires an aperture of about f/0.9 to f/0.92) and has the same cogging like the focus ring to support video applications (follow focus) as well. It is shipped with M-mount and an adapter to E-/X-/EF-M-Mount depending on your order. It covers APS-H sensor size but with its large rear element (diameter 36mm) it does not fit into the throat of current Leica-M cameras or Ricohs GXR module. For more details please see this article.
- Mitakon 35mm f/0.95
This lens is a very solid construction as well with 10 lens elements and a 10 blades aperture. It has good haptics, weighs about 680g and comes with E-mount. Prices I have seen so far varied between 700 (eBay auction) and 1000 US$ (private auction). The lens is manufactured in China and until now I did not see a dealer that offers it with warranty.
- Canon EF 50mm f/1.4 lens + Metabones Speed Booster (converting to a 35mm f/1.0 lens)
This combination of a 50mm f/1.4 full frame lens and a focal converter provides you a lens with 35mm focal length and an aperture of f/1.0 still covering the size of an APS-C sensor. To understand that functional principle please see Metabone's white paper. The adapter is designed to transmit /convert also the electrical signals to the lens in order to control aperture setting and autofocus (on selected lenses) by the camera. The Canon EF 50/1.4 lens is about 400 US$, the adapter costs about 600 US$ when ordered in Hong Kong.
- Leica Summilux-M 35mm f/1.4 ASPH
This lens is designed with 9 elements, one with aspherical surface and 9 aperture blades. It is very compact and weighs only about 320g. Some people say it is still the "35mm/1.4 reference". Prices are about 5000 US$ (new and about 4500 US$ used).
- Samyang 35mm f/1.4 AS UMC
This lens is designed for fullframe DSLRs and constructed with 12 lens elements (some aspherical) in 10 groups and an aperture with 8 blades. It weighs about 712g. It is availabe with different mounts and has an attractive price of about 500 US$.
- Leica Summicron-M 35mm f/2.0 ASPH
This even more compact desgined lens is propably the smallest 35mm f/2.0 fullframe lens avaiilable today. It is designed with 7 elements (one aspherical surface), has an 8-bladed diaphragm and weighs 254g. Price is about 3200 US$.
In this article we will cover
- overall comparison
- center-sharpness of the f/0.95 and f/1.4 candidates at open aperture and F1.4 as well as edge sharpness (of the 0.95 candidates)
- bokeh (rendering of the out-of-focus areas and the shape of the circles of confusion of highlights) at F0.95, F1.4 and F2.0
