Hi all,
I just adquired an Oly 100-400 after a good think about this, because I had the 75-300 (light and very sharp for it's price and category) and the 40-150, always excellent at low light, with TCs, stabilization and AF speed. But the 40-150 is so short for birding, almost for me.
Two days ago I received the Oly 100-400. Not surprises because I had read a lot of reviews in the web. I went to a waterland to proof this lens, a locality with diversity on birds and raptors, close to my home. I take about a thousand of pictures... and so sadly for me I don't keep none. All images were blur, noisy, horrible!!!! Just two weeks before I was in the same site with the 40-150 & 75-300 and take very good pictures!
But the ones taking with the 100-400 were horrible. I thought that my lens was damaged, but today I've done proofs with a sharp chart and the 100-400, the 75-300 and the 40-150. The 100-400 was in sharpness very good, between the 40-150 and the 75-300 as expected.
So the problem could be different. I think my SIS configuration is not good (only the body SIS autos in the EM1-x) and the AF click in CF tracking. I have read in this chat that the AF_C tracking could be a problem with this lens. I need to experiment more. Other advices are wellcome!!!
