For the past week I have had the opportunity to check out Olympus’s newest lens. The M.Zuiko ED 300mm f4.0 IS PRO. This thing is absolutely amazing and probably one of the SHARPEST lenses I have ever used. Not only is it tact sharp, but it’s incredibly FAST. All of the following images were taken with the 300mm and in a couple cases, I also added the M.Zuiko Digital 1.4x Teleconverter MC-14 . Because of the Olympus sensor, the focal lengths are 600mm & 840mm equivalent. This lens has built-in image stabilization and when used in tandem with the 5 axis in-body image stabilization of the OM-D series cameras it creates 6 steps of shutter compensation. Everyone of these images were handheld.

Fantastic shots Frank. Glad you included the Eagle photos, I know the lens is sharp but I was not sure how well it focused on moving subjects. btw: were the Eagle photos taken at Conowingo Dam?
Stuart, Thanks. The lens is amazingly sharp & fast. Yes, the Eagles shots are from Conowingo.
Frank beautiful images (as usual). The pics pop and the lens looks like a major winner PLUShandhreld!!! Amazing.
Walt, Thanks! It’s a FUN lens!
Breathtaking!

Thanks!
Very well done as always Frank! I have and use all the 4/3rds SHGs except the 300 F2.8 and see no reason to purchase it now, but rather couple this lens with the EM-1. Bokeh looks very smooth, despite some saying it is busy on other sites posted examples. Though pretty specialized, this lens is definitely tempting me! I might have to get back into birding just to be able to use it 😉
PS: I wish you’d include at least speed and aperture settings along with your posts!
Thanks
David, Thank for your comments. The lens is one of the sharpest I have used (and fast). As far as my settings, I shot handheld at 1/800 or 1/1,000 at f4.0. My ISO ranged between 640 & 3,200.
