Testing out the Commlite CM-AEF-MFT Lens Adapter on Olympus OM-D EM-1 (Birding)

I have been using the Olympus system in my birding photography for sometime until I find the reach a little too short for my liking and gotten myself the Sigma 150-500mm instead. I used it on my Canon 7D.

Subsequently in my attempt to consolidate my gear, I sold off my Canon system and decided to use the Sigma lens via the mc-11 converter on my Sony a7ii. Then, I find that one of the downside of using crop mode on the Sony is that I lose pixels and the reach isn't much different.

So I decided to get the Commlite CM-AEF-MFT lens adapter and try the Sigma lens (and possibly all other Canon EF lenses) on the Olympus system. 

Birding with the Canon 7D and Sigma 150-500mm F5-6.3 APO DG OS HSM

Today I went out birding at the nearby lake with my Canon 7D and Sigma 150-500mm F5-6.3 APO DG OS HSM. It's not a light combination, the lens alone is 1780g and together with the body it's around 2.6KG! I do not carry a bag or any accessories along, so it's basically just the camera and lens attached to my Black Rapid strap. 😁

The AF-tracking was responsive and it's not hard to lock-in focus in such bright daylight, although not all photos taken are keepers (which is normal). 😉

Setting is basically the widest aperture, auto ISO with shutter speeds of 1/600 if the bird is stationary or 1/2000-1/4000 if it's moving.

Here are some of the photos taken:

Retrospective: Using the Nikon AFS 70-300 VR lens adapted to the Olympus OM-D E-M5

*This is one of the blog entries written in retrospective based on my recollection of the events which took place earlier. 

I went to the zoo in an outing one day. As I was curious as to how the Nikon AF-S 70-300mm f/4.5-5.6 VR can perform with the 2x cropped sensor of the Olympus, I brought the lens along with me.
