Sony Alpha NEX Cameras and E Mount Lenses

EyeAF Comparison Metabones vs Sigma MC-11 Canon to E-mount Autofocus Adapter Here's a video by Luis Gabriel Photography showing the EyeAF difference between the Metabones Canon EF/EF-S Lens to Sony E Mount T Smart Adapter vs the Sigma Mount Converter MC-11 . The camera used is the newest a7r iii camera controlling a Sigma 135mm f/1.8 Art lens. The video shows how viable it is using Canon EF lenses on the new a7r iii . This makes switching systems easier.

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.

Canon 6D vs Sony NEX-7 with Metabones Speedbooster Tarocoo wanted to see what the NEX-7 with the Canon EF to E-mount Speedbooster can do against his full frame Canon 6D . He had access to a multitude of manual focus lenses which can be used on both E-mount and EF mount (EOS). The Speedbooster's final EFOV on the NEX APS-C sensor is about 1.1x the focal lenght - so the EFOV is close to the Canon 6D with the full frame sensor. The lenses used are: Sigma 24mm f/2.8 Sigma 28mm f/2.8 Olympus 35mm f/2.0 Sigma 50mm f/1.4 The images will show the whole scene at wide open to an aperture of f/11. It will be followed by center and corner crops at same aperture range. Here we go...

Sony NEX-7 with Speed Booster vs Nikon D600 TheCameraStoreTV posted their hands on video with the Metabone Speed Booster for NEX cameras. They used the Canon EOS to NEX Speed Booster lens adapter on the NEX-7. In the video they compare the NEX-7 and the Nikon D600 , a full frame camera, to see if there are perceptible differences. They used a Sigma 35mm f/1.4 DG HSM lens on both cameras. The exposures were set to be equal at ISO 200 and aperture set at f/8. The NEX-7 with the Speed Booster registered and aperture of f/5.6 due to the full stop of light from the adapter. The D600 registered f/8. The image above is a side by side comparison at 400% enlargement. Would you be able to tell the difference? Check out the full hands on video with the Speed Booster below.

Mockup of Sigma 60mm on NEX-7 Sigma is adding a third lens to their Digital Neo series for E-mount cameras. It is the 60mm f/2.8 macro in native E-mount. The lens is similar to the one found in Sigma's new DP3 Merrill. Here is Sigma's description of the 60mm DN. Sigma 60mm F2.8 DN- Featuring the natural perspective of mid-range telephoto lenses, together with a shallow depth of field, this lens allows the photographer to capture a single part of a subject with great bokeh effects. It has an angle of view equivalent to 90mm on the E-mount system (35mm equivalent focal length). The minimum focusing distance is 19.7 inches; the maximum magnification is 1:7.2. This lens also contains Special Low Dispersion (SLD) glass, which helps minimize axial and transverse chromatic aberration.

NEX-7 with Voigtlander 15mm, Sigma 30mm, and Fujinon 50mm lens Here is a set of pictures by Emmanuel C. taken in Turkey with his Sony NEX-7. He brought along a pair of adapted manual focus lenses: Voigtlander 15mm f/4.5 Super Wide Heliar and the Fujinon 50mm f/1.9 lens. He also used the native E-mount autofocus the Sigma 30mm f/2.8 DN lens. This provides a nice set covering 22.5mm, 45mm, and 75mm equivalent field of view.

R.C. at LensRentals.com performed a test on several lenses on the NEX-7. The lenses comprised of the native E-mount lenses from Sony and Sigma. A Leica Summilux was also thrown into the mix since it's done well in previous Imatest challenges. The numbers below represent MTF-50 at aperture f/4. The NEX-7 was set at ISO 400 and each lens was manually focused and bracketed so that focus errors were eliminated. from Imatest. Device or system sharpness is measured as a Spatial Frequency Response (SFR), also called Modulation Transfer Function (MTF). MTF is the contrast at a given spatial frequency (measured in cycles or line pairs per distance) relative to low frequencies. The 50% MTF frequency correlates well with perceived sharpness— much better than the old vanishing resolution measurement, which indicated where the detail wasn’t. Now let's look at the test results at aperture f/4. Lens Max Avg Sony 16mm f/4 915 646 Sigma 19mm f/4 920 765 Sony 24mm f/4 1000 ...

The Sigma 19mm and 30mm f/2.8 EX Digital Neo (DN) lenses are in stock at Amazon. These are the first 3rd part autofocus *prime* lenses for the NEX system. The 19mm EX DN translates to 28.5mm equivalent FOV on 35mm and the 30mm EX DN translates to 45mm EFOV. The tests below are by jerome_munich. Sigma 19mm f/2.8 EX DN on NEX-7 by jerome_Munich Sigma 30mm f/2.8 EX DN on NEX-7 by jerome_Munich Check out more photos by jerome_munich .

Here are quick mockups of what the new Digital Neo lenses from Sigma will look like on the Sony NEX-5N . Both prime lenses from Sigma will work with the NEX's autofocus system. The 19mm f/2.8 DN lens translates to an FOV of 28.5mm and the 30mm f/2.8 DN translates to an FOV of 45mm due to the NEX APS-C sensor. Both lenses have a maximum aperture of f/2.8 and f/22 as a minimum. The filter size is also the same at 46mm. The Sigma Digital Neo lens system was announced at CES 2012. We are hoping for more DN lenses soon. NEX-5N with Sigma 30mm f/2.8 Digital Neo Lens The Sigma 30mm f/2.8 DN is a 7 element in 5 group lens construction. The lens weighs a mere 4.8 oz (135 grams). The minimum focus distance for the 30mm DN is 11.8 inches which means a maximum magnification of 1:8.1. from Sigma This high-performance standard lens is designed exclusively for mirrorless interchangeable lens cameras and has the equivalent angle of view as a 45mm (35mm equivalent focal length) on the E-mount syst...
