Hi Oscar Agree with the above. You get full marks getting the focus, dead on - sharp details on the bird. Also this is a nice job of handling the exposure which looks like it could have been a problem but wasn't.
Hi Oscar Head angle aside the image is sharp with the converter !!! Doing well !! When using do take lots to choose from since not all will be sharp, will be a low keeper rate !!!
Did also well with the exposure, if anything would brighten the bird up a little bit in curves !!!
