"RF mount also adds data bandwidth, moving from eight communication channels to twelve."

Being a bit picky here, more electrical connections doesn't necessarily add data bandwidth (that depends...

Actually, the really nasty ones there are probably water drop lens effects. I'm talking about, for example, the bokeh in the first shot. There seems to be a distinctly bright edge on the bokeh. ...

Strange to see Sony sensors in Panasonics; I thought Panasonic made their own sensors and was pretty serious about that...? I think Sony's been doing a great job, but it's a bit sad to see they...

Built like a classic king of the gods of Mount Olympus?  ;-) Images look very crisp, but bokeh are a bit disappointing with a bit of a bright rim. Not that I particularly trust him, but Ken ...

Of course, there's no way to know until you have it in hand. However, that doesn't look like an active fungus infection to me -- I think that IS the etched glass. Active infections usually look ...

Well, that's not what I see out of my 50/1.7.  Don't get me wrong -- it is a very good lens -- but pretty much all 50s are good in resolution and I have some better than this. I don't have a test ...

Excellent point. The big problem with these is that IQ (especially distortion and vignetting) tends to be very dependent on the match between the base lens and wide-angle add-on converter, but ...

Unless you're adding a focal reducer, being closer to the sensor than the designed rear focus distance of a lens does not "reduce crop factor" -- it merely causes focus beyond infinity. I don't ...

You mean the following don't exist? https://www.ebay.com/itm/Micro-4-3-m4-3-Lens-To-Sony-NEX-E-A7-A7R-A6000-A5000-NEX5R-NEX3N-NEXC3-Adapter/132521287388?hash=item1edae25edc:g:3-cAAOSwcUBYFrvC:rk:2:pf:0

Optical bench is different from real life use. On a test bench, everything is mechanically aligned and tiny errors show easily. In real life, one tilts the camera slightly, etc., to obtain the ...

Actually, much of computational photography isn't about "cheating" at all -- it's about having better creative and technical control. Probably most researchers in computational photography are ...

I've done shots like this with a camera literally bolted to a concrete block and still failed to get perfect alignment, so I don't know why you think your tripod is so perfect. Either the camera + ...

Yeah, and the upper left is better in the other image. This is the kind of change a tilt a tiny of a fraction of a degree could make. Bad adapter? Well, let's see how carefully you kept things aligned:

That's 24MP. You know film-era lenses were never intended to resolve 24MP on an APS-C sensor... which, incidentally, would be more like 58MP on FF. Optimizing for film isn't the same as optimizing ...

Aha. Ok, is this the MFT one (but by Rokinon name)? It gives identical specs to the FT one I pointed at above: 13 Elements in 12 Groups, 8 blade diaphragm, 77mm front, etc.

Resolution, dynamic range, etc. are all so much better than film was that there is a natural slowing in those dimensions, but things are evolving quickly: for example, faster pixel readout and ...

You know there are MFT to Sony E adapters available in the $10 price range...? You Adaptall lenses weren't designed for the high pixel density nor thick cover glass of MFT -- they'll make better ...

That's a really good question. Samyang has at least two different 24mm f/1.4 designs: This one for Sony E and this one on many mounts including MFT .  I'm assuming you're looking at the second one. ...
