Fujifilm XF 18mm f/1.4 R LM WR

Pros: Excellent, from many points of view. Sweet spot (best focus), f/2.8, 94 lp/mm, MTF = 0.5. I think it's the best of Fuji.

Cons: Nobody

Opinion: Fujinon XF 18 mm f/1.4 R LM WR: built in 2021, modern design. Compact (68.8mm x 75.6mm) and medium weight (370 gr). Filter diameter ø58mm AF excellent, fast and quiet. On X-T3, freehand, it is better to shoot with times less than 1/54 of s On X-T4, freehand, no shake problem. In the best focus, sharpness (MTF) excellent at full aperture (f / 1.4) and remarkable, about 0.48 at f / 16 even for high spatial frequencies (45 lp / mm). At the edge of depth of field, absolute sharpness with respect to full aperture (f/1.4) and up to f/16 for moderate-low spatial frequencies (15 lp/mm). For high spatial frequencies (45 lp/mm), at the edge of depth of field sharpness (MTF > 0.4) well above the limit of acceptability from full aperture (f/1.4) up to f/16. Sweet spot (best focus), f/2.8, 94 lp/mm, MTF = 0.5. Up to the frequency of 45 lp / mm is never penalized by the resolution of the sensor of the X-T3 or X-T4, that is, for any aperture, the MTF of the lens in the best focus is always lower than that offered by the sensor at the same spatial frequency. The MTF of the X-T4 sensor, evaluated at the spatial frequencies that experimentally characterize the isoMTF = 0.5 of the lens, is not always larger than 0.5. In fact, for apertures from 1.4 up to f/5.6 the MTF of the lens is greater than the related MTF of the X-T4. I think this is one of the reasons why Fujifilm recommends this lens for X-H2 or X-T5 cameras.

Fujifilm XF 33mm f/1.4 R LM WR

Pros: Good, fast and quiet AF. On X-T4, freehand, no shake problem. Sweet spot (best focus), f/4, 79 lp/mm, MTF = 0.5.

Cons: On X-T3, prone to shake. Freehand, it is better to shoot with times less than 1/100 of s

Opinion: Fujinon XF 33 mm f/1.4 R LM WR: built in 2021, modern design. Compact (67mm x 73.5mm) and medium weight (360 gr). Filter diameter ø58mm AF good, fast and quiet. On X-T3, prone to shake. Freehand, it is better to shoot with times less than 1/100 of s On X-T4, freehand, no shake problem. In the best focus, sharpness (MTF) excellent at full aperture (f / 1.4) and remarkable, about 0.48 at f / 16 even for high spatial frequencies (45 lp / mm). At the edge of depth of field, absolute sharpness with respect to full aperture (f/1.4) and up to f/16 for moderate-low spatial frequencies (15 lp/mm). For high spatial frequencies (45 lp/mm), at the edge of depth of field sharpness (MTF > 0.3) well above the limit of acceptability from full aperture (f/1.4) up to f/16. Sweet spot (best focus), f/4, 79 lp/mm, MTF = 0.5. Up to the frequency of 45 lp/mm it is never penalized by the sensor resolution of the X-T3 or X-T4, that is, for any aperture, the MTF of the lens is always lower than that offered by the sensor at the same spatial frequency. The MTF of the X-T4 sensor, evaluated at the spatial frequencies that experimentally characterize the isoMTF = 0.5 of the lens, is always larger than 0.5. Definitely a perspective to recommend. To be coupled to the X-T4.

Fujifilm XF 60mm f/2.4 R Macro

Pros: Compact (64x71 mm) and lightweight (215 gr), On X-T4, freehand, no shake problem. (t

Cons: AF uncertain, slow and noisy. On X-T3, prone to shake. It is better to shoot, freehand, with times less than 1/180 of s.

Opinion: Fujinon XF 60 mm f/2.4 R Macro: built in 2012, relatively old design. Closeup 1:2 and not Macro 1:1. Compact (64x71 mm) and lightweight (215 gr) Filter diameter ø39mm. AF uncertain, slow and noisy. On X-T3, prone to shake. It is better to shoot, freehand, with times less than 1/180 of s. On X-T4, freehand, no shake problem. (t
