For Olympus M.Zuiko 300mm F4 IS PRO Lens in SLR & MFT (micro four thirds) Lenses
Recommended
Yes
Price
0$
Pros
  • Weight, Image quality, weather and dust proof, build quality
Cons
  • None
Having used this lens for 2.5 years now, I can second what has been written so far. I would like to add the following positive aspects
- Build quality
- Effective weather and dust sealing
- Compact and highly portable
- Very fast and reliable focusing (EM-1 Mark 2 or EM-X for best results thanks to the cross points)
- To benefit from the dual IS you need to pair it with an Olympus body, other makes are not compatible meaning you have to select lens or camera IS
- Works fine with the 1.4 TC
The price tag may seem a bit high however considering the image quality it is well spent money.

For 70-300 lens in SLR & MFT (micro four thirds) Lenses
Recommended
Yes
Price
0$
Pros
  • Cost, size
Cons
  • Slow to auto-focus
I have used this lens for 1.5 years now with an E-520 body (with built-in Image Stabilizer) and must say I am really satisfied with the performance. It is a "standard quality" lens but the results are good and the lens is capable of delivering sharp images. It is also moderately priced and well suited for taking bird shots so if you have a 4/3 camera and looking for a telezoom I would definitevely recommend.


Im my opinion it performs better than the 40-150 mm standard telezoom that often is included in the Olympus kits. (If you are prepared to accept a slow auto-focus, as several have pointed out. I haven't updated the firmware, though).

Other:
I take (virtually) all my shots hand-held.
Thanks to the 4/3 format the size is really compact for a telephoto lens (80 x 127 mm)
Weight is 600g
The lens has a 58 mm thread which is also a potential cost saver on the filter side
Close range is 1.2 m so the leans also works OK for shooting smaller creatures


Hope this feedback is useful
