XF 90mm F2 Focus Issue (blur)

[Rafael Fischer]

Hi!

I Just got a Fujinon XF 90mm F2 from a store during a trip thru Colorado and when arrived home in Brazil, I started using it but since the begning I'm having trouble with focus issues as folows:

The lens aquire focus quick and without problems, but, if as farther the subject is, blurrier it gets... Even manual focus have the same problem, the pictures looks like you applied a gaussian blur in any image. Focusing close subjects, the pictures are sharp as expected, just the the distance increases, the blur follows the distance... I've tested with 4 different camera bodies (X-T20, 2 X-T3 and a brand new X-T5)... The lens glass is pristine and spotless as is the lens body and everything else. Use the warranty is harder as I'm in another country :-(

Anyone have seen this issue?

I too have that lens but have not seen this behavior - I'm replying to see if others have answers.

I am shooting the Zoo tonight (Zoo Brew...craft brewers on hand) I'll take my 90 and test it as well but I have yet to notice any infinity or near infinity focusing issues, it's my favorite XF glass btw.

OP where you able to get this issue resolved? I bought a second hand xf 90 and have experienced the same issue as you. I have mine in for service for another issue following a fall, but I asked them if they could check it out.

No, I had my lens sent to a Fuji service center in my country and they were able to identify the issue but the cost was half of the lens, so, I Returned to Colorado where I got it... They said that the problem was in the focus block assembly and the new part isn't easy to find outside Fuji itself.

Okay, thanks for answering. After I wrote this, I saw your post at DPreview as well. I bought mine used, so no warranty for me, sadly.

My lens wasn't new, but the Store in Denver where I got it second-hand, give me the option to return it and I did...
