Fuji X-S1 - Sample Images: ISO Performance

Audley Jarvis

By Audley Jarvis



Our Score:


At ISO 100 the Fuji X-S1produces sharp, noise-free images

ISO 200 is almost identical to ISO 100

At ISO 400 some slight softening has begin to creep in, but you'll need to go looking for it at 100% or more

By ISO 800 image softening is more visible, with increased noise in shadow areas

By ISO 1600 shadow detail has really begun to break down, though the image remains useable at smaller sizes

Noise and a softening of detail is easily visible at ISO 3200, even at smaller image sizes

Because ISO 6400 requires you to shoot at 6MP, the overall image size is smaller. Quality isn't great either

ISO 12800 requires you to shoot at 3MP and the results are fairly terrible

Thanks for the review, I have been interested by this camera for a while. I currently use 2 Canon DSLR's (550d and 60d), one usually with Canon 15-85mm lens and the other a Canon L 100-400mm, to cover all eventualities. As the X-S1 covers the same range in one convenient package, would I be disappointed with its image quality? I always shoot RAW, and have been disappointed with bridge cameras in the past.

Hi interpleb,

To answer your question I think the X-S1 produces fantastic image quality compared to other superzoom/bridge cameras, however it can't really compete with either the 60D/550D in terms of overall image quality - especially with regards to sharpness. This is simply the price you pay for cramming such a huge focal length into a single lens. The flipside to this, of course, is that the X-S1 is much more flexible/portable than a DSLR and a big bag of lenses.

I think it all comes down to what you want to do with your images really and how critical your eye is. If you're only planning to make small prints (4x6inch or suchlike), or viewing your images on a 13-15inch laptop screen then I'm sure you will be perfectly happy with the X-S1's overall image quality. If, however, you want to make poster-sized prints for your walls then you're better off sticking with the 60D/550D.

As to the second question you raise, if you shoot in Raw then you will of course have much more scope to manipulate your images post capture. Fuji has bundled some Silkypix conversion software with the camera for exactly this purpose.

Thanks for the informative review of the Fuji X-S1.

As an owner of a Fuji S100fs I have been following this camera since it was announced. It looks as if Fuji have finally produced a superzoom that might be a suitable upgrade for the S100fs.

I recall the favourable reviews Trusted Reviews gave the S100fs and the S200exr and would value your opinion regarding how the image quality of the X-S1 would stack up againgst that of the S100 or S200.

Thanks for a really useful website.

In reply to Audley`s reply to Interpleb i utterly disagree with his assumption that Fujis X-S1 is only capable for producing 4x6 prints, this assumption is tottaly `rubbish` for heavens sake even some small compact cameras were perfectly capable of producing A4 prints several years ago (technology has moved on since then Audley) now some are capabile of producing A3`s as is and should be of the X-S1, secondly, to state `as long as you view the X-S1`S pictures on a 13-15" laptop screen` is also tottaly `rubbish` i view my X-S1`s images on a 17" HP laptop screen and most of its pictures look fabulous, indeed i have viewed some X-S1 images on a 23" screen and they look the same, i would not be put of buying the X-S1 based on Audleys comments, indeed i would beleive that if any other camera websites reviewers implied that the X-S1 was only capable of producing 4x6" prints then in all sense the camera should only be awarded 1 out of 10 overall, we all know by now that the bridge cameras cannot yet match the high and mighty SLR`s but they are running a very very close second.
