Sony ALPHA TIP # 195: #SonyTIP #Sony An interesting READ, not just for the Review of the HandeVision IBELUX 40mm f0.85. But, for the GEEK In-site from someone that sees a LOT of Lens and have taken some apart. :) ... (this is one of my take aways) and YES, its available in E-Mount. From Roger Cicala LensRentals Review: A Quick Geek Point I end up knowing a lot of stuff about lenses I probably wish I didn’t. One of those things is that a lot of “specialty” lenses designed by one company and manufactured by another have absolutely no compensating or adjusting elements. The lens is assembled basically by stacking all the elements in place. If the company does any quality control, it consists of taking some shots after the lens is assembled. If it’s awful, it gets disassembled and the parts get put back in their bins with the hope they’ll match up better with other parts when they get put in another assembly. And yes, I know this first hand. Because of inevitable manufacturing tolerances, this means some lenses are pretty good optically, some are absolutely crap optically, and buying one is like a box of chocolates – you never know what you’re going to get. And whatever you get is what you got. There are no optical adjustments that can be made. This is what I thought we might see with the Ibelux 40mm. But we did open one up, not to do a complete teardown, but just to peak inside. What we found was most reassuring – there were shims to adjust tilt and centering associated with several of the elements. That not only means the optics can be adjusted. It also means someone was checking each element as it was placed, determining if it needed to be shimmed and how much. Which means my hopes for this lens as I headed to the test bench increased exponentially. This was a real optical device assembled with some care, not a bunch of glass elements stacked together on a hope and a prayer. lensrentals/blog/2014/08/kipon-handevision-ibelux-40mm-f0-85
