Low Light with the Speed Booster and Contax 50mm Planar

“speedster

Songstress.



Here are some photos from a wedding we invited. All we were equipped with was our trusty Sony NEX-7, a Metabones Speed Booster, and the Contax 50mm Planar - a gem. The Speed booster gave us an effective 55mm lens at f/1.2, necessary for this low light event.


“speedster

Double trouble.



The NEX was set to shoot jpeg only in black and white with contrast and sharpness at negative two. This made the post-processing much easier than usual with cropping as the only requirement.

Getting the Shot Sony A7r II vs 5d Mark III

Bokeh Battle 85mm Zeiss Otus vs Sony G Master


The video above from DigitalRev TV shows the advantage of electronic viewfinders found on Sony cameras. The evf betters optical viewfinders by providing a more accurate way to manual focus lenses. The Sony A7r II provides a magnified view for focusing. It also has focus peaking which highlights portions of the image that are in the focus zone. So getting the shot with the Otus is a much easier task with an EVF.

Another advantage shown is that Zeiss only provides autofocus lenses for Sony - the Batis line. The A7r II had no problems locking focus with the 85mm G Master. Canon and Nikon shooters can only use the Otus and Milvus line, which Sony shooters have access to as well.

Hands On with Zeiss 35mm Distagon on Sony a7r at Photo Plus

sony a7r zeiss 35mm distagon leica samples

Zeiss 35mm f/1.4 Distagon on the a7r


Here is the newest Zeiss lens for the Leica M system. It is a Distagon 1.4/35mm ZM lens - Carl Zeiss' fastest lens for rangefinder cameras. We stopped by the Zeiss booth at Photo Plus and tried it out on the Sony a7r with a close-focus adapter. Voigtlander makes a better version of the adapter but this one works for us.

The 35mm Distagon ZM feels like a fine piece of machinery. The aperture from f/1.4 to f/18 have soft click stops. The focus ring is smooth, well damped, and pleasing to use - we prefer it to the Otus' ring. The lens is dense and heavy for such a small size thanks to the all metal construction. The 35mm Distagon ZM is deceptively heavy as the 85mm Otus ZE is deceptively light.

Jeff Koons: A Retrospective Whitney Museum


We discovered that the Jeff Koons exhibit was on its final days at the Whitney Museum. We also learned that the Whitney was closing the doors at the Breuer Building location and was moving downtown towards the Highline. We took the Sony A7r and a Contax 28mm Distagon and tested out GeoTagging - posted earlier. Here are some images from the excursion.

Zeiss 35mm Distagon ZM Announced

Mockup of Zeiss 35mm f/1.4 ZM on Sony A7r


Carl Zeiss announced their fastest ZM, Leica M mount, lens at Photokina 2014. The new Distagon T* 1,4/35mm ZM is designed for the Leica M digital sensor but we are hopeful that it will work well on the Sony A7 cameras with the appropriate lens adapter. Above is a mockup of what the Zeiss 35mm f/1.4 lens would look on a Sony A7. The Zeiss 35 f/1.4 will provide subject isolation through shallow depth of field.

Sony SEL1635Z Mounted on a Sony A7s from PhotographyBlog


The wait is over. People have been hunting for a wide angle lens for the Sony A7 cameras ever since the full frame e-mount cameras were released. Some have been using the Sony 10-18mm at 16-18mm with great results on the Sony A7 bodies. Above is the new Zeiss 16-35mm f/4 Vario Tessar FE ZA OSS Lens or SEL1635Z, announced at Photokina 2014. It is fully compatible with E-mount cameras with autofocus and auto aperture control. The lens is designed for the A7 and will cover the 24x36mm sensor. The SEL1635Z will also work with the Sony a6000 and NEX cameras where it will provide a EFOV of 24mm to 52mm, nice walkaround lens range.

Below are specs for the SEL1635Z and samples from Mark Galer who has been using the SEL1635Z on the Sony A7s.

Zeiss Loxia 50mm on A7r Samples and Review by Berlin Backstage

zeiss loxia review sony a7r

Zeiss Loxia 50mm Planar on Sony A7r


Berlin Backstage was lucky enough to test out the new Carl Zeiss Loxia 50mm f/2 Planar lens before the Photokina 2014 official release. Here are a points we extracted from their review titled "Blau trifft Orange," translated blue meets orange.
  • 180° of focus ring movement for gentle, precise focus.
  • Aperture ring can be de-clicked for videographers with a supplied de-click tool.
  • Feels similar to the Zeiss 50mm ZM Planar lens.  The Loxia 2/50 is a massaged ZM Planar design for the Sony A7 series.
  • The f/2.0 maximum aperture keeps the lens small which is a good compromise.
  • The Loxia is a manual aperture lens, not electronic controlled.
  • It provides Exif data to the camera.
  • The lens hood can be mounted in reverse without blocking the focusing ring.
  • Ten aperture blades for buttery soft bokeh.
  • Important points for the reviewer: feel, color, contrast.
See the sample images from the Loxia 50mm on the A7r from Berlin Backstage below.

Zeiss Loxia 35mm and 50mm Lens Specs for Sony A7 Cameras

Here are the specs for the upcoming Loxia lenses by Carl Zeiss designed for the Sony A7 family and other E-mount cameras. The first two announced are the Loxia 35mm f/2 Biogon and the 50mm f/2 Planar.  Both lenses share the same physical dimensions and filter ring thread.  They are manual focus lenses with electronic coupling to Sony E-mount cameras.

Sony E-mount Lens Roadmap Updated


Updated Lens Roadmap for E-mount Cameras




Macro G Lens and High Speed Prime Zeiss Added to 2014 Release



We just noticed that the E-mount lens roadmap has been updated to provide detail to the two upcoming lenses. The roadmap suggests that we will see three more lenses before years end. One will be a Sony G Macro lens - our guess? 100mm f/2.8 macro, similar to the Sony 100mm macro.

The other lens will be a Zeiss high speed prime lens - our guess? 24mm f/1.4 maybe more of a wish. This lens could be based on the NEX's 24mm f/1.8 ZA Sonnar or the A-mount Zeiss 24mm f/2 Distagon.

Sony A7r and NEX APS-C Lenses

Carl Zeiss 32mm Touit Lens on Sony A7r


Here are a bevy of autofocus lenses made for the Sony NEX system mounted on the new Sony A7r. The red boxes show a 1:1 or square aspect ratio and a 16:9 aspect ratio. The lenses have rear baffles which were not removed. Most of the prime lenses can provide a square image with a little bit of vignetting. 16:9 images show heavy vignetting, maybe we can extract a 2.35:1 Cinemascope / Panavision image with the A7r's 36 megapixels to play with.

Zeiss 24-70mm FE Autofocus Speed Test

Zeiss 24-70mm FE ZA with the A7r


Zeiss 24-70mm AF Speed Test


SLR Club posted a video of the autofocus speed of the new Zeiss 24-70mm f/4 ZA FE Vario-Tessar lens. This lens is made for the new Sony A7 cameras and covers its full frame sensor. This lens will also work on NEX aps-c cameras and will have an equivalent fov of 36-105mm.

We are wondering how this lens compares to the Zeiss 16-70mm E ZA lens which is for the aps-c sensor. Both lenses share the common features. They have image stabilization, maximum aperture of f/4, and are dubbed Vario-Tessar by Zeiss.

Zeiss Touit 12mm f/2.8 in Cape May

sony nex-7 touit 12mm carl zeiss

We thoroughly enjoyed the Zeiss Touit 12mm f/2.8 Distagon on a recent trip. We spent a few days in Cape May, NJ with the Touit 12mm glued onto the NEX-7.

We are still learning this ultra wide angle lens, at 18mm efov on the NEX, most everything will be in frame. We are somewhat addicted to the NEX-7's level feature which helps minimize converging vertical lines with such a wide lens. We also depended on the NEX-7's autofocus mode while using focus-recompose to frame. Here are a few shots from the trip. They are all RAW converted shots.

Sony A7 Hybrid vs Contrast Detect Autofocus

Sony A7 Hybrid Autofocus


It may not be obvious to us but the hybrid autofocus, phase + contrast detection, of the Sony A7 is faster than the contrast detect only focus. The A7r does not have hybrid autofocus, more from this previous post.

Samples from Zeiss 35mm and 55mm Sonnar FE and Touit 50mm Macro


Here are some samples we were able to take at PhotoPlus Expo. We tried the three new Zeiss lenses which are the 35mm f/2.8 Sonnar FE, the 55mm f/1.8 Sonnar FE, and the 50mm f/2.8 Makro Touit. The Zeiss FE lenses were located in the Sony exhibit alongside the new Sony A7 cameras. Both the 35mm and the 55mm Sonnar FE felt at home on the Sony NEX-7. They were neither heavy nor enormous on the NEX. The Sonnar FE samples were taken using autofocus. Click on them and they are 100% crops from RAW files from the NEX-7. We didn't have enough time with the lenses but the results are excellent.





The Zeiss Touit 50mm Macro Planar was stationed at the Carl Zeiss exhibit. We were lucky enough to speak with Dr. Pollman, Zeiss Program Manager, about the new Touit 50mm Macro. He stated that this is their first 50mm macro which can provide a 1 to 1 magnification. The shots below are manually focused at minimum focus distance of the Touit 50mm. Click and find the full processed raw file (20+ mb) from the NEX-7. The shots are very revealing - we cleaned the Touit 12mm, the lens in the picture, after seeing the shots at 100%. Just like the other lenses in the Zeiss Touit lens line, the 50mm Macro will not dissapoint.

Sony A7 and A7r Hands On at PhotoPlus Expo

Sony A7r with a Voigtlander 12mm Lens and Viewfinder


It was a very crowded Sony booth at PhotoPlus. The great thing was the Sony representatives were very accommodating to anyone who wanted to play with the new Sony A7 and A7r. We had our bag of lenses and was able to mount them all on the A7 and A7r - check out the 12mm viewfinder on the A7r above. The lenses include the following:

  • Voigtlander 12mm f/5.6 Leica Thread Mount on a helicoid adapter.
  • Voigtlander 35mm f/1.7 Ultron LTM.
  • Minolta 24mm f/2.8 Rokkor MD.
  • Contax G 28mm f/2.8 Biogon.
  • Contax Zeiss 85mm f/1.4 Planar with the Metabones Speedbooster and the standard C/Y adapter.
  • Zeiss 12mm f/2.8 Touit Distagon.
The cameras were pre-production and the use of memory cards to record the images was prohibited. We wanted to see if I could see immediate problems on the rear tilting lcd but none were glaring.  The only noticeable issue was color shift with the Contax G 28mm Biogon.  We're hoping that this can be remedied with the production models.

Below is the Contax 85mm Planar on a Metabones Speedbooster. As you can see it cannot cover the whole sensor but with APS-C mode on the A7 cameras the Speedbooster is still useable.

The Voigtlander 35mm Ultron LTM was a nice surprise.  This lens gives the NEX-7 some problems with color shift but on the A7 this was not the case.  The few snaps that we took looked great on the rear lcd.

The Minolta 24mm f/2.8 MD provide a nice wide angle image on the Sony A7.  It felt nice and balance on the slightly larger frame of the Sony A7.

We were very excited to mount the Zeiss 12mm f/2.8 Touit on the new Sony A7.  We had the A7's APS-C lens detection off to see how much the Touit can cover the full frame sensor.  The lens has a plastic shroud to protect the rear element and this showed up in the shot below.  The Touit works perfectly fine in APS-C mode.
