Yesterday, I went out to get some stormy skies photography, and brought the 7DmkII paired with Canon 400mm f/5.6 prime lens. Don’t get me wrong, it’s a good lens, but without stabilization, I found most my photos had some variation of motion blur, as it was low light, focusing on a distant subject, hand held. Not the best lighting for a non IS lens.
Today, I took the 400mm, mounted it on the Kipon EF to MFT adapter, and put it on an Olympus OMD EM1. I swear this lens and body were made for each other. Even though the lens is an f/5.6 on a full frame, the equivalent on the EM1 is an F/2.8. Couple that with the in body stabilization, the lens being Non IS is no longer an issue.
You have to remember this when using this combination, because if you don’t your images will probably be a bit dark, and when shooting at ISO 800 or above, that can lead to excess noise. You will see 5.6 flashing in your viewfinder. You have to ignore that. I know, goes against everything you’ve learned.
I shot this at f/6.3 +0.7, ISO 800, 1/120 exp.
The image is sharp, colors are great, and even the bokeh is sweet.
