XF 90 - Worried about the bonk !

Hello. After some advice.

I recently bought the XF90 & am loving it.

Anybody that has one will know that, when the lens is powered off, you can hear the focus mechanism bonking around inside, especially if you hold it horizontally, and lower first one end by an inch, then the other end and so on.

Now I've never owned a lens that did this before. I know it's the way it's designed, and I've read that the 50-140 and many Canikon lenses do it.

Now, I always carry all my gear in a rucksack. 2 bodies & 7 lenses along with a small tripod & a flask of tea.

I'm English.

I walk many miles .. thousands of steps .. each week, and every step that I take, with the XF 90 sitting in the rucksack, will result in a couple of bonks.

So many thousands of bonks per Month.

..and it's not just a little click, it's quite a hefty thump each time.

So I guess what I'm wondering is, is there any point in worrying about long term damage to a lens that has something bonking around inside ?

I can't find any info from Fuji on this .. you know, tested & guaranteed to be ok for a million bonks, or whatever.

I discovered that if I pack the lens so it's always vertical when I have the rucksack on, the number of bonks is reduced greatly.

Guess that'll help a bit.

Curious as to what any of you may have found out about this over the years, using bonking lenses from other manufacturers...

a.       Don't even think about it .. designed to take it...

b.       Minimise the bonking and you should be ok .. be aware of it..

c.       Don't put the lens in the rucksack unless you know in advance you may need it...

or any other thoughts !!

Ta.

me too. A. I was wary at first but I'm sure it will be fine.

 

Either that or a mass recall in the future...

 

Mine does make a load of crazy noises, almost like a fax machine. Also makes like a triple click when you turn it on as well.

Still doesn't worry me.

      Image correction with GF20-35

      Ahh, the infamous brick wall photos… 😀 According to internet lore, if the dng converter does not properly apply the corrections, you can have it apply custom profiles that should work for you. How to do that is waaaaaay outside of this comment’s scope, but there are plenty of sites listed in the search engines that step you through the processes. Best wishes.

      Jerry Thank you very much. That is extremely helpful. It seems that the camera and the lens have the latest firmware update, so it appears that the corrections should be applied automatically. The lens arrived this afternoon and I took some quick test shots, in which the correct lens information appeared in the EXIF files, so that sounds good. I used Adobe DNG converter to convert the Raw (RAF) files, and then opened the DNG files and saved them in PSD format. However, with a beautiful, clear, cloudless blue sky, there were no lines near the edges to check if distortion had been corrected. Another day I plan to photograph a brick wall. Thank you for your help.

      Typically you need to make sure the lens is compatible with the camera, i.e. check the lens compatibility charts for your camera, then make sure the respective firmwares are updated so older issues are resolved. After that, each lens has a manufacturer’s profile which will be embedded into the raw file meta data for the images captured using that lens. From there, it is up to the raw conversion software to apply the lens correction to the image. Different converters do that differently, some automatically, some only if a setting is turned on. For in-camera jpegs, the on-board converter does the corrections automatically, assuming the camera recognizes the lens, it applies a generic profile otherwise. I do not know if that can be turned off or not.

      How does one make sure that Fuji's image correction is turned on to correct barrel and pin-cushion distortion on a GFX 100 or GFX100S when using the GF20-35? Is it only applied to the jpegs and not to the raw files? (I was surprised to discover the barrel distortion on the GF 35-70mm lens.) I normally shoot in raw with jpeg back-up and use the raw files, which I convert either in Affinity Photo 2 when editing with that program or in Raw File Converter Ex 3.0 by Silkypix if I wish to process the image in Photoshop CS6. (Adobe DNG is also a possibility.) Thank you for the help. Trevor
