Oh man, I was browsing ard @ the homepage when the 'little tuna' caught my eyes. I'm v impressed with the Oly lens! Amazing.
150mm f/2 is equivalent (35mm) to 300mm f/2 ? I looked up the price is $3,500. Gosh, compared to the 300mm f/2.8, it's a good buy. Or am I missing something. Please advise, I'm pretty new to Oly technologies.

More details with Little Tuna plus EC-20.

The FourThirds sensor is half the dimension-size of 135-format sensors (or "full-frame" in marketing-speak); as such the effective focal length is therefore doubled with respect to 135-format.
Or looking at another angle:
If you slap on a 100mm lens on a 135-format camera, you get the reach of 100mm.
If you slap on a 100mm lens on a Nikon DX camera (of which 135 is 1.5x the dimension size), you get the reach of 150mm, and DoF is 1.5x deeper per f-stop.
If you slap on a 100mm lens on a FourThirds camera (of which 135 is 2x the dimension size), you get the reach of 200mm, and DoF is 2x deeper per f-stop.
Cheers guys
I thought I should share these results and hopefully, those who are using or thinking of using Oly for wildlife applications can better judge their options
Egnaro, the sunbird was shot in the Singapore Botanical Gardens and the Blyth's Hawk-Eagle was shot at Bunker Trail in the Panti Forest Reserve Johor.
Microcosm, my friends and I recently did a shoot-out with this lens and the Nikkor 300mm f4. Critical equipment deployed were 3 kopi peng kaos, one teh see, 4 kaya toast with butter, some otah, comfy chairs and air-conditioned surroundings. Oh and we also used a Gitzo 2541L and a loser Manfrotto ball-head with quick release.
Test shots were a char siew rice stall at about 30 yards and a A4 sized notice with normal sized print posted on a glass wall was the centre target. We mounted both lenses (150 + EC-20) on my E-3 (using an adapter for the Nikkor) and manual focused on the notice using live view magnified 10x.
To cut a long story short, there wasn't much to choose between the two at full size but the Nikkor has the barest of edges (I'd put it down to contrast). So I'm satisfied with the lens' performance even with EC-20.

I'll certainly do that when I get the chance.
I've always figured that primes will perform better than zooms and despite claims that the Zuiko zooms are really as good as primes, I have found my Zuiko primes to be better than the zooms. My 50-200mm SWD is not able to deliver what the Little Tuna can with a EC-14 attached, in terms of detail and contrast.
So right now, I'm looking at the 300mm f2.8![]()

Right on Drakon09
But gotta try the 90-250 too!
All I can say is the 50mm f2 thrashes the 35-100 f2 at 50mm but yeah, yeah, yeah... its a macro... but still :bsmilie:
Maybe I'm missing somthing here but if we're comparing a 4:3 lens to a 35mm equivalent shouldn't we multiply both aperture and focal length by 2?
ie 150mm f2 on a e-3 is equivalent to 300mm f4 on film or fullframe dslr?
