Pros: Super sharp with amazing stabilisation
Cons: Quite pricey

Well itís been a while since I let my Canon big glass go due to my ageing frame complaining about carting the weight around. Iíve been using our trusty Canon 400mm F5.6 since letting the 300mm F2.8 go, however, now that Helen has fully embraced the joys of telephoto photography we decided it was time to invest in a second telephoto lens to avoid arguments.

After much googling and rumination we decided to invest in a M43 lens, as Iíd already been using a Panasonic GH4 for video work and panoramas for a couple of years. After comparing the two M43 telephoto options on our shortlist, the Panasonic 100-400 and the Olympus 300mm F4 PRO we finally decided, on the basis of looking at images and reviews, to go with the Olympus 300mm F4 PRO plus the matching MC-14 1.4 teleconverter.

Our primary interest in this lens is from the perspective of shooting birds, so the lens first real test was a Treecreeper close to our local canal.

At the time these shots were taken, I was still waiting for the teleconverter to arrive, so the shots were with just the 300mm lens, mounted on an Olympus EM-5 MKII.

The distance and size of the subject meant that the Treecreeper was quite small in the frame, so this is a good test of the lenses ability to stand up to a tight crop, a scenario that most of us photographing small passerines are used to.

I should add that uploading the lower image to my blog seemed to soften it a bit, the image is actually even sharper than this.

Bearing in mind that these shots are hand held, I have to say that Iím already extremely impressed with the Olympus lens. The lens has an in built stabiliser system which operates in addition to the sensor based stabiliser on the Olympus EM-5 MKII. The combined effect is quite amazing. As you look through the EVF, on half depressing the shutter release the stabilisers kick in and the image you are presented with magically transforms, looking like youíd suddenly put it on a tripod (Iíve read that Olympus hand select the gyro sensors for these lenses and I can well believe it!)

Thereís obviously a lot more to think about with this combination. Iím interested to see how itís close focusing (down to 1.4 metres would you believe) works for dragonflies and other small subjects like lizards, and thereís also still the question of how well the auto focus performs over time compared to equivalent DSLR combos.

Weight wise, I'd say your looking at something very close to the classic Canon 400mm F5.6, so it's not super light, but given the performance characteristics of the lens, I would say you'd be carrying something getting on for double the weight and size to get equivalent performance with a Canon or Nikon equivalent. That being said, I'm aware this isn't a simple like for like comparison, and some reviews, directly comparing this lens with the Canon 600mm F4 are I think overstating things a bit.

Iíll endeavour to keep posting about this lens, as I didnít find a lot of information online for bird photographers about it. First impressions though are immensely positive, roll on June and our trip to Mid Wales where Iíll be seeing how the Olympus combo copes with Red Kites.

Useful review. I am thinking of pairing it to my recently acquired GH5. I am using a PL100-400 with some good results (better now with the GH5). I just prefer primes - as they will (obviously) always be sharper - and the f4 wide aperture is also a big, big bonus.

Thanks for sharing.
