Olympus MC-14 1.4 x Teleconverter for Olympus 40-150 f2.8

Hi Denjw

Good questions, here's my take, I hope they help you.

I think the MC-14 is great it certainly adds a different dynamic and I believe performs better than my 1.4 converter on my FF kit.

For me its so good it will stay on the camera as the default. I can offer no scientific proof (others are good at that) and honestly am far more interested in the results and the confidence that I can get the shot I want.

It it helps you ive put 4 images in a flickr album below as a comparison the first 2 are with the MC-14 and second two not. All with the f40-150 f2.8. I was standing on the opposite touchline at Saracens rugby ground the photos are all of line outs at the opposite side of the pitch so the view and distance are similar, both are on full reach. The Exif stuff is there so you can see more detail. I should say the second 2 were late afternoon and at 4000 ASA so please take into account.

Your question on focus technique, i've just added v3 firmware and the recommendation is to use C-AF tracking which is very good, it doesn't always get the first shot in focus but normally, I also have one of my front buttons set to re-centre the focus, not sure this is necessary but it gives me confidence where the focus lock will start from, so I am happy with is - my previous experience is with Nikon where back button focus was the best solution I have used to date. Wish I could do this on the EM-1. For me still more practice to go, if I think I've cracked it completely I will share it here
