Question: What size filter does this lens take?
Document: I've own several 35mm equivalent (mirrorless) lens and this Fujifilm 23mm f/1.4 is the best of them all.This is a well built, sturdy lens. Similar in style to the Fujifilm 35mm f/1.4 lens.It's quite big actually, the filter size is 62mm. It weighs 300g so it's going be slightly front heavy on the camera but I've found that handling is comfortable so the weight is not an issue.On the barrel, there's still the aperture ring.
This will pay off because this lens takes the same 62mm filter threads as the 56 1.2.I adore this lens.Enjoy!
This is arguably one of the most versatile and sharp lens that Fuji ever produced. It's now stays permanently on my XT-1. So many good things to say about this lens... what I like best about it is (i) size... nice and compact, easy to bring around to any location; (ii) sharpness... simply mind-blowing; (iii) feel... you'll have to hold/use one to appreciate it... very solid feel.
I've not used full-frame 35mm lens before but I never will because of their size and weight.Focusing is fast, not DSLR-instant fast, but fast enough, close or similar to the Fujifilm 35mm f/1.4 lens. I'll not be using this lens to shoot running subjects.It's definitely value for money. Most highly recommended.It's pricey, relatively speaking compared to other Fuji lens.
This lens superior in almost respects to the XF 35 mm and XF 18 mm, which I also own. It offers edge to edge sharpness and clarity, a clever ring to switch between manual and automatic focus, bokeh, and a much improved lens cap. In addition, the focusing is noticeably faster than the other two lens. As other reviewers have noted the only flaw is the clunky lens hood which is difficult to install and causes the de rigueur UV filter to loosen.
This is great because I am able to capture sharp pictures at night at 1/60 second at F1.4 at ISO800, with lots of ISO room to spare. Whereas, with the 27mm lens, I would need to be at ISO3200 to take the same shot at 1/60 second.
Love this lens on the Fuji.
I can happily carry all three lens and an X-Pro1 body all day.
This lens is a wonderful addition to my other Fuji prime lenses. extremely sharp and love the focus ring. very smooth lens.
nice optics and very good build. It's a little bit bigger than I hoped, but it's outstanding lens and I am really happy to have it
Answer: This lens takes a 62 mm front filter. It is a wonderful lens.
