Some scenes are idea for the rendering at f1.2 While others work better with f1.6 and beyond. No question about it.   Two tools in the same lens.

The f-number is the ratio focal length to the diameter, d, of the entrance pupil, which in cameras is the aperture . The amount of light through the pupil is pi*(d/2)^2 . One full stop is twice ...

Most likely most of the hordes of people just waiting for Fuji to come to its senses use other Fuji cameras and any increase in sales of such a XPro will come at the expense of cannibalizing other ...

1. Remove the LCD from the XPro.  Instead integrate a top shelf communications subsystem and develop a top of the line phone app to replaces the LCD similar to what Leica did.  Replace the LCD ...

Yes if not very careful in shooting angle relative to the sun lenses of this speed will flare.  Even hoods won't really help.  It simply an issue with light rays from the outer edges of the lens ...

The X-Trans IV is a BSI sensor with higher read out.  The BSI most likely is what accounts for the 1/3 stop better sensitivity.  The read out speed of the X-Trans IV is better which makes it ...

Not only that they would be sued by Sony.

Hi Phillipp, It's off - in that is it not working.  However, one of the downsides of IBIS is the sensor is floating. It is not physically connected.  It rides on magnetic actuators.  So even if it ...

I expect the Pro4 won’t be around to 2024 - a little early to worry about it. But on my list would be better manual focusing aids. Making it thinner would be nice.

I used DXO primary with my Nikon.  It was not an option when I transitioned to Fuji.  I tried Aperture and sure didn't like the anal "I am the master of your files" that was their catalog. Capture ...

It seems to me that DXO is a day late to the party.  C1 has come a long way in the last few years since 2016 when I bought my XPro2.  I was a DXO user at the time, and had to switch.  C1 today has ...

I've never used it.  I just checked, it two does not use any aspherical elements.  Fuji chose to design the 90 and 200 strictly using expensive ED and Super ED elements.  That is why the rendering ...

AF-C, low burst rate, 3x3 zone focus should work fine with the newer bodies.

It may or may not happen.  Sigma is doing their own calculation on how to maximize their R&D investment.  Bottom like Sigma doesn't give a rat's behind about you or I or anyone else using a Fuji ...

Since Fujifilm seems to refuse to clone the formula in a 70 mm lens - there are not options.  It's Fuji's best - I wish they would bring out its twin a 70 f2 in the same optical formulation.

It is the only Fuji X lens that does not use aspherical elements. Aspherical elements while addressing spherical aberration also produce poor out of focus rendering, hard edges around bokeh balls, ...

Yes.  It is Fuji's best.

I thought I had put this up - maybe on a different thread.  Not a formal portrait but an informal one in my barn. As is no cropping except to a 4x5 aspect ratio.  Taken in the barn isle with open ...

Not to be confrontational.  However, I can point to a metric for the optical property of resolution and spacial frequency response.  I can point to a metric for the optical property of acutance. ...

Almost right. Resolution refers to Rayleigh resolution. It measures how closely together two point sources can be and be seen as separate by an optical system. It limit is given by x=1.22*lambda/N ...
