The Olympus M.Zuiko ED 40-150mm f2.8 PRO ($1,499.99) is a serious lens. It covers a longer telephoto zoom range then the standard pro 70-200mm zooms when paired with a Micro Four Thirds camera, and is incredibly sharp from edge-to-edge throughout the entirety of its range, even at f/2.8.

Edge-to-edge sharpness throughout zoom range; No distortion; Protected from cold, dust, and splashes; Excellent close focus capability; Innovative collapsible hood; Manual focus clutch system; Includes tripod collar

Pricey; Lack of optical stabilization an issue for Panasonic Micro Four Thirds shooters

I'm using this lens with a Panasonic GX8. I'm primarily a still photographer. I've used Nikons for 50 years, but use the GX8 and M43 because of the weight, even though there is some reduction in image quality (not due to this lens but to the M43 format), especially at low light or higher ISOs...

This lens is why I packed my OM4T up, put in on the shelf and finally went M4/3. Olympus finally gave me a reason to switch. The reason I used my OM4 for so long was portability. The 40-150 on my M-1 returned the Olympus advantage to digital. This lens is best with the 1.4 teleconverter.

Advantages: 1.excellent image quality; 2. fixed max f2.8 aperture; 3. I just love this focal length range--for me it's the perfect outdoor and portrait lens. It just fits how I typically see the world! Disadvantages: 1. Relatively large; 2. Relatively heavy (compared to other micro 4/3 lenses); 3.

Field tested this lens photographing sea otters. Took 700 frames with this lens and the OM-D E-M!. Took 700 frames with the Nikon D810 and the new Nikkor 80-400 mm VR II. Could not see and difference between the two set ups in terms of image sharpness, overall image quality, or single shot autofocus...

Super sharp and lightweight

The OM-D E-M1 body does not year support continuous autofocus

"I've own many micro four thrids lenses since adopting the system. I'll be honest, some haven't met with my expectations. While many lenses in the system are superb by any measure, a large number are what you might call consumer-grade glass good, but not acceptable for professional work by today's...
