These are the poorest construction i've ever seen in lenses. Iris guidance ring is actually threaded and using a thin screw to control the blades, no isolation but contrary on the 40mm M43 those whole comunicate directly with the optical elements in the lens, no o-rings, manufacturer (if we can call it like this) says you can not use focus motors on their lenses, also not calibrated from the factory, asymmetrical vignette, loose screws everywhere. Poor poor construction and strange technical choices made inside the lens. These will require at least 2 times per year service. Image wise is great, too bad for poor construction and QC.
this is powerful bro
Very nice job. Great song. And great movement. Location was beautiful. Where are you guys located?
Thanx! In Russia (Moscow and S.Petersburg)
