I recently had the chance to test the XF 100-400 with the X-T10. It is a very sharp lens, and is fairly light compared to the Sony 70-400 II. These images are not processed.

It is an extremely sharp lens. However, these images look pretty soft to me. Perhaps applying some sharpening in post might help, but I'm not sure your AF is spot on here. What exactly were you focused on? Keep in mind that the DOF at 400mm can be very small.
 
The AF was not exactly spot-on on either of them. My photos are certainly not as sharp as the other ones posted here.
 
This was also my first time shooting with a Fuji System, so was unsure of how everything worked on the X-T10

Takes some getting used to, but as you can see from the many examples posted here, it's definitely possible to get razor sharp images with that camera/lens combo. Keep at it and don't hesitate to ask for help. There's no lack of expertise here.
 
To help to match AF sensor and target using a light monopod does help a lot especially on small targets such the eye of the bird or head versus body

I use it with my other gear a sigma 150600 on Nik 7200
 
Its a case of practice...its that simple...there are so many reasons why shots might not be perfect (to your eye)...

I was practicing on gulls for bif on a local pond just after Christmas,,not a great keeper rate...but... I was shivering as it was bloody cold with quite a strong easterly wind (a cold direction in uk winter) and numb finger tips!! Together with dropping (rapidly) motivation,,I gave in as the lure of a hot cup of tea proved to hard to resist !!

The settings you use,,how u hold the camera,,the light,,experience with the equipment and experience with the subject all have an impact on final image quality...for example,,in this thread Baobob has pointed out using a monopod,,I personally go out of my way to avoid using tripods/monopods,,perhaps I might change my idea on this when I get a larger lens...try different things and see what make your images better or worse and go from there...

The 100-400 fuji is a great lens and next on my shopping list...have a look at "Jerryastros" zoo shots...that will be enough motivation to keep at it for sure!!

I am interested in this lens, it looks great from all the posts and youtubes.

Please post more images, if you would. Thanks

The only thing stopping me is the Af speed for tracking BIF, if it can keep up with BIF on Xt-10, then it would be a go for me

Thanks again for sharing your images

Happy shooting

Well thanks VERY much for the nice comments about the zoo pics, Dave. Much appreciated. i'm not a huge mono/tripod fan either, particularly if your subjects are not static or at least a good distance away. The OIS on the lens is nothing short of amazing and I've had pictures taken at 560mm (with TC) stable at 1/250s. I wouldn't recommend that as a standard practice, but it does demonstrate what is possible.

Loved your comment on grabbing tea after a trying and very cold practice session. I continue to be impressed and amazed at the dedication many photographers here have for their craft, and it shows in their images. Alas, it also reminds me of far I have to go still...

I decided to test out the lens a little more today, and the photos are coming out very soft, even more so than yesterday. The bokeh is also very unsightly and not pleasing to the eye. I am even taking sharper images with Olympus 40-150 F 4-5.6, which is a 200$ lens! This photo was shot with a tripod and the remote on the app.

On tripod did you turn off the OIS? If so then there is definitely something wrong with the lens. Though your shutter speed is very slow, it shouldn't be an issue on tripod.
 
It looks like these images were impacted by shutter shock. Have your tried the electronic shutter for comparison?

Yeah something doesn't seem right. Shutter speed perhaps? I don't see anything in focus. Are you accidentally moving the zoom ring while shooting. I did that a few times when I first got the lens. Maybe a bad Copy. Try to take a photo at a higher shutter speed with IS turn on and off and or on a tripod on on a counter to eliminate any movement to rule out optic issues

I know this camera can take really sharp images based on my recent experience.


Thanks

I just tried it with electronic shutter now. Here is the image. Still very soft. Once again shot with tripod and smartphone remote. All of the photos on this thread are with O.I.S.

I put the focus point exactly on the eye. It was shot from my smartphone though, so might not be too accurate.
 
can you turn O.I.S off and try again? I once had a lens that had bad IS and when I turned it off it fixed the issues... had to send the lens back.

Thanks

Robert
 
Here is a shot without O.I.S Once again shot with tripod and smartphone remote.

Seems pretty likely that you have a bum copy. I would likely contact the dealer and get it exchanged. That image is just as soft as the previous examples. It looks as if it could be camera shake as well, but if you are using remote on a tripod, it would seem less likely.
