Leica announced today the new X-U (Typ 113) underwater camera, which essentially the underwater version of the existing Leica X (Typ 113) camera. Familiar specs for the new Leica X-U include a 16.2MP APS-C CMOS sensor and a fixed Leica Summilux 23mm f/1.7 ASPH. lens. [Read more…]
In this short video, Gary Fong takes a look at full frame, APS-C and 1.0-type cameras to see how the depth of field is affected at the same effective focal lengths.
The challenge, of course, is that you must change the actual focal length of your lens to accommodate the same field of view on cameras with different sensor sizes. Invariably, this changes the depth of field so that the camera with the smaller sensor appears to have a much greater depth of field, while the full frame camera has a much shallower depth of field.
Gary’s demo is a nice practical demonstration of how these different camera sensors provide different images when shooting the same scene from the same position.
The upcoming Tokina AT-X 11-20mm f/2.8 PRO DX lens went up for pre-order today at a $599 retail price. It should start shipping on March 2, 2015 for both Canon and Nikon mounts.
This is an APS-C format lens, which results in about a 17.5-32mm full frame equivalent field of view. It has a nine-blade diaphragm and internal focusing. Check it out here at B&H Photo.
