www.soundimageplus.blogspot.com has some nice pictures as well produced by the Samyang 14mm lens. Click the tag for the lens.
The only issue is that the lens was built for a DSLR, and naturally, it isn't exactly light.
I wouldn't mind trying the lens though. It looks excellent as a wide-angle prime.
It's not very heavy really, the specs must be wrong. I think I better weigh it, or maybe I'm just getting stronger :bsmilie:
(* correction, this is referring to Samyang 8mm, I just noticed that you were referring to 14mm)
On m4/3, one can get away using it as a UWA if on a tight budget, it's not very fishy-eyed, one can probably de-fish it. Like this pic below, and I am shooting it from about 1 foot off the ground pointing upwards. I composed it to make the long piece of the machine straight. This is at f/8 iso 800 in the night, it is easier to go below 1/20 shutter speed with a UWA, and I did not even bother to focus.
This one is with the Lumix 7-14mm at 7mm, also about 1 foot off the ground pointing upwards.
So the curve at the sides on the Samyang pic is really very slight. One can still make it more curved or even straighter, with slight changes in composition.
The most striking feature of the Samyang, which also surprised reviewers, is the very low distortion on the sides and corners, in terms of resolution for example, compared to the other images shown here. It is excellent in this aspect. Probably because of this, quote from Lenstip.com - "Not only does it use difficult-to-implement stereographic projection but it also completes its basic tasks"
Ken Rockwell's review of it in his website against the much higher-priced Nikons also shows the difference this design can make.
But if one wants a more pronounced fisheye, then this Panasonic 8mm looks good for m4/3. It also can get closer to .1mm, which is good for even more dramatic foregrounds. And it sure is beautifully small.
But at SGD 490 (+ adapter though), this Samyang is great, if one can live with its size on m4/3. However, only from f/5.6, best from f/8, and forget f/3.5 really. Also, it has to be calibrated by the owner (although the factory should do it, since those who don't know will think the lens is bad, I don't see any logic why the factory should not calibrate it before shipping)
