Possibly. The issue comes when matching two different lenses together with the same exposure within the same lighting situation. Using T-stops you can calculate equivalent exposures and trust that...

Small production run, extra mechanics for a stopless aperture, extra teeth for interfacing with follow focus.

Also keep in mind that Samyang lenses already have production runs without focus...

I would be curious if they have done anything to help the lens be a true parfocal lens. As you zoom the point of focus will invariably shift - it seems like since it uses the same optical design...

It's paying for the small production run, extra mechanics for the stopless aperture, and the added external teeth for interfacing with follow focus.

It's the same lens so you can expect it to operate the same way. Of course with modern processing CA is not really much of an issue unless you enjoy viewing at 1-1.

T stop or transmission stops are the relative real world amount of light coming through the lens accounting for absorption by the lens elements. The lens itself is the 16-28mm f/2.8 but in reality...

No - the X-Trans sensor is unique to Fuji.

I'm excited - much of the cost is in materials and smaller production runs. Brass isn't exactly cheap after all.

Further not all photography is about absolute perfection - we frequently add...

If it had an F-mount it would be SLR sized as the F-mount specification requires the distance between the sensor and lens mount. It would definitely not be a pocketable point and shoot.

@JDThomas: Oh I know that not all of them are - the bulk of the recent sensors have been though.

As for Canon I doubt those are exactly the same sensors - it's very likely that there are numerous...

Being fair Nikon sensors are Sony sensors with Nikon processors behind them. That said Canon has seemingly done nothing to update that 18mp sensor for a long time now.

As for picking what camera...

Which image are you looking at specifically? I'm not seeing aliasing at 100%.

My guess is that they only have two manufacturing lines and in order to produce another mount they have to stop the EF or F lines temporarily. Given the massive market share's that Canon and Nikon...

Given Pentax's small market share it probably doesn't make sense financially.

It would be nice but given the tiny market share it probably doesn't make sense financially.

Given the stellar Sigma 35mm 1.4 that just came out I would hardly say they're ignoring a growing market.

It's an interesting lens. The MSRP is a little high for what it is. At that price point it's dangerously close to the Sigma 120-300 f/2.8 OS which is a good (albeit larger/heavier) lens. That said...
