Those guys from Samyang are my favorites! They have a history of extremely well made lenses for a very low price. And I was pretty sure that their first Micro Four Thirds lens, the 7.5mm f/3.5 would have a decent image quality. While I am by no mean a Fisheye fan at least they really designed that lens for the m43 sensor! Unlike Sigma that in order to save costs designed the 30mm f/2.8 for m43 and NEX and the result is a big and slow lens :(
So it that lens really good? There is now a full review at Photozone (Click here): “the dwarfish and very light-weight Samyang is not only a pretty good lens it is also a very affordable one and as such we can recommend it to all ultra-wide angle enthusiasts out there!“. And the lens gets “highly recommended” which doesn’t happen very often! Go Samyang! Make more lenses like this! ;)
Now to buy this lens you have to keep in mind that the name changes depending from the country:
In USA it’s named Rokinon 7.5mm and you find it on eBay (Click here), Amazon (Click here) and BHphoto (Click here).
In Europe it’s named Samyang 7.5mm and you find it on eBay (Click here), Amazon (Click here),
In UK it’s named Walimex and you find it on eBay (Click here) and Amazon UK (Click here).
