Since my principal reason for moving to the Micro 4/3 format is cutting down on size and weight, these things matter to me. In addition, the Samyang 8 mm, although not a large lens compared to other APS-C lenses, is quite heavy, and cannot be called small (especially when mounted on an adapter, see picture below) compared with typical Micro 4/3 lenses. This has good effects (the peripheral areas of the image circle, which display the highest aberrations and distortion, are left out) as well as bad effects (the diagonal angle of view becomes significantly less than on an APS-C sensor). However, the 8 mm covers an image circle quite a bit wider than the Micro 4/3 sensor.

The Samyang 8 mm of course can be used, with an adapter, also om Micro 4/3 cameras, and in fact the image quality is remarkably good (see example above). I am now in the process of moving from APS-C DSLRs to the Micro 4/3 format (mainly with an Olympus OM-D E-M5). Image sample with Samyang 8 mm on Nikon F to Micro 4/3 adapter and Panasonic G3 camera. I reviewed it here, and found it very satisfactory, although difficult to focus through the optical viewfinder of a DSLR. Incremental updates appear throughout the current year.In 2009, Samyang introduced a relatively cheap, manual-focus 8 mm f/3.5 fisheye lens for APS-C cameras.
