If you want to test Olympus equipment, I have a 40-150 2.8 and 300 4.0 for you too try out. If wanted i also can assist you in the shed and give you good tips
and advice on bird photography. You can also borrow an Olympus E-M1X and try the eye focus on birds.
Olympus 300 4.0
Olympus 300 4.0 is a very sharp drawing fixed lens with formidable range. All in a small and compact lens. The near limit is very good at 1.4 m.
Bright and sharp lens with a very good close range of 70 cm. With a focal length that goes from 40-150 provides both the opportunity too get pretty close and images with more environment included.
The flagship of Olympus is a solidly built camera body with the best image stabilization on the market. The camera also has eye recognition for birds, a great news that completely changes the way you shoot.
Now you have the opportunity to test it out on birds of prey in the forest shed. I also want to show you how to use the button on the back of the housing for focusing, the so-called back focus button, which you can read more about here.
