Sony 135mm F1.8 GM First Hands on Look

Earlier today Sony introduced two new products – a telephoto portrait lens from the G Master series – the Sony 135mm F1.8 GM and a BT wireless remote that works with the recent Sony cameras. Sony held an event in NY and ordered several photographers and bloggers to test the new lens and the videos here have all been done with the lenses at the event.

The new Sony 135mm F1.8 GM is an impressive feat of engineering with many interesting features. It has 13 Elements in 10 groups  (including an XA element, Super ED and ED elements), no less than 11 rounded aperture blades and both nano and Fluorine coatings.

Even more interestingly it has 4 linear motors which Sony claims turn the lens into a super fast AF lens (possibly the fastest in its class), De-click switch two programmable buttons and AF/MF switch as well as a focus limiter.

Talking about focus, this lens can focus fairly closely (compared to other fast 135mm primes), it has a min focusing distance of 70cm/2.3 feet and a max magnification ratio of 1:4 which is rare for a lens of this type.

The lens isn’t small or lightweight (2.09 lb/950 grams), about 1/3 more than the Zeiss Batis 135mm f/2.8 but about 200 grams less than the Sigma 135mm f/1.8 (Sony FE version). The lens is also dust and moisture-resistant.

Here  is a list of the main specs of the lens:

  • 13mm f/1.8 lens with full-frame coverage.
  • 13 Elements in 10 groups including XA Element, Super ED and ED Elements.
  • Nano AR and fluorine coatings.
  • XD Linear Motor AF System (including 2 front and two back motors).
  • AF/MF Switch and focus limiter switch.
  • Two programmable buttons.
  • De-click Switch.
  • Dust and moisture resistant.
  • Aperture: Rounded 11-blade diaphragm.
  • Price: $1900, available in late April 2019.

Sony also introduced the RMT-P1BT wireless remote commander which uses Bluetooth connectivity, eliminating the need for wires, cables or receivers to connect the remote directly to the camera (it also doesn’t have the restrictions of the Sony IR remote and hopefully it will not activate two close by cameras as the IR remote does).

The remote has some useful functionality including – focus, shutter, record, zoom adjustment, two assignable buttons, lock switch and a LED indicator light. The remote can be used for both stills and video operation. Sony also mentioned that the remote will have a very fast reaction time of just 0.05 seconds (good for action shots).

The new remote will work with most recent Sony cameras including the Sony A6400, A7 III, A7R III, and A9. The remote will sell for $80.
