In reply to Paul Phillips - UKC and UKH:
First one was taken on an iphone camera “blindly” fired!! It was only taken just to get a reference picture from above to confirm ID - it was a 6ft fence so not possible to get a photo otherwise.
Second photo, was a trial of an OM1, I have had an Olympus OM-D EM1 mk2 for a few years now and like Olympus, coupled to an Olympus 300mm IS F4 prime (600mm FF equivalent).
Initial impression testing both the OM1 and the 300mm lens is they are both a significant improvement in many ways over the previous camera/lenses I’ve got to be worthwhile upgrades for bird photography I’m getting into this year.
