Earlier, I posted some examples of images made in two ways: Using the shift function of the GF 30/5.6 T/S lens with the sensor parallel to the target. Using no shifting, yawing the camera to put the target in the same place in the image, and using Photoshop in postproduction to make it seem as… [Read More]
Fujifilm 30mm f/5.6 T/S lens — sharpness, shift vs postproduction
Lensrentals has loaned me a Fujifilm 30mm f/5.6 GF tilt/shift lens. I’m getting ready to send it back, and I asked on DPR if there were any tests that anybody wanted me to run. One reader asked that I compare the sharpness of shifted images vs ones that applied the same sort of corrections in… [Read More]
GFX 100 II pixel shift
I got a complicated question that may interest others, so I’m going to answer it here. If it’s on your radar, I’d be interested to know if the GFX100ii pixel shift is improved at all from the GFX100s. It appears to be the same to me, except for the 4-shot mode. I use it on… [Read More]
Sample variation in the Fujifilm GF 100-200 at 200mm, revisited
A reader chided me for not using the same methodology when testing my copy of the Fujifilm GF 100-200 and another reader’s copy. To review, I tested my copy with a very complicated program that analyzes stacks of focus bracketed images, white balances the raw MTF curves, fits curves to critical measures, and calculates metrics… [Read More]
Sample variation in the Fujifilm GF 100-200 at 200mm
When I measured the performance of the GF 100-200mm f/5.6 lens at 200 mm, I got good, but not great results. In fact, it was about the weakest performance I’ve seen with the excellent line of GF lenses. Ever since I published those results, people have been saying that their copy of the GF 100-200… [Read More]
