Flare Issue - 10-24mm

Hi All, I recently started using my 10-24mm for a project where there is a lot of shooting in the afternoon with full sun in the frame. In the course of this I discovered that my copy of the 10-24mm exhibits truly terrible flare when shot at smaller apertures. This image was shot at f/11, 10mm. The flare is much less apparent when shooting at wider apertures, where it becomes just a general veil of reduced contrast rather than these specific spots, and so you don't see it in the viewfinder until pressing the shutter release.

 

I've checked all the usual culprits eg. no filter, clean lens glass etc, but still it remains. I figure the spots may be internal dust (albeit I cant see it) but the magenta and green stripes are something else altogether. Can anyone else duplicate this result?

I am sure this is a combination of culprits, ultimately this is an extreme wide-angle zoom with many elements in a complex array it has all the compromises of being an extreme wide angle and a zoom put together.

 

In that picture which you have shot, the sun falls practically orthogonally into the lens. This is bound to cause internal reflections but also causing dispersion, breaking the light into the spectral wavelengths components, plus the tiny aperture takes care of increasing the lens diffraction causing the milky appearance, loss of contrast and resolution.

 

I have terrible weather over here ( and will stay like that for days) but I am sure that mine would show similar results under similar circumstances.

 

I have decided to sell this lens, not on account of any of this “ problems” but the fact that I use it, practically, only at its 10 to 12 mm setting. 

 

So, I might as well buy a Samsung ( which is credited to have the same sort of problem, so don’t run to conclusions) 12mm and employ the considerable difference to buy other lenses that I might equally well use.

Having said this, the 10-24mm has given me immense pleasure in using it and I have no complaints at all.

Just as Milandro said, I would be super surprised to not have any lens flare at the angle you took the shot. It is good that Fuji isn't violating some laws of physics ;]

 

[...]I might as well buy a Samsung[...]

 

I assume you mean Samyang, right ?

oops yes I have no Idea how that went wrong..... :D

 

Are you looking to buy a new smartphone maybe ? Or even worse, would you comparing the efforts of making lenses by Samyang in the same category as Samsung's attempt to break into the mirrorless world ?

Looks pretty bad.

10mm f/16 white LED as a front light source, several dust particles added to sensor and to rear lens element.

Funny, I found the best horror happens when frame composes with LED placed on thirds intersections. :)

      Looking for Full Frame lenses to adapt to GFX

      By Giampaolo Masserano · Posted

      I use a TECHART ring to mount Canon EF lenses on the GFX 50S-II and 100S-II, maintaining image stabilization and autofocus. The only limitation are lenses with a small rear element diameter that make it impossible to cover medium format. Fast lenses like the EF 85/1.2L or the 100-400L, however, work great.

      Looking for Full Frame lenses to adapt to GFX

      I also use a Nikon to GFX Fringer and it works very well.  24mm f/1.8 vignettes so best used on 35mm mode.  50mm f/1.8 covers the entire frame very well with no issues and is a superb little lens. 105mm Sigma vignettes slightly but is perfectly usable. 300 f/4 likewise the 105.  I have a 70-200 f/20+.8 incoming to test so will report back but I'm expecting a little vignetting.  Even in 35mm mode the image is still 60MP and if you're prepared to manually crop and correct you can get 80-90 MP images.  I also have a C/Y to GFX adapter.  The 24mm Sigma Superwide vignettes strongly. Ditto 28-80 Zeiss Sonnar. 80-200 f/4 Sonnar is perfectly usable. All work fine as 35mm mode lenses.  I also have an M42 adapter which I tried with the Carl Zeiss Jena 135mm f/3.5 with good results.

      Image correction with GF20-35

      By jerryy · Posted

      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.

      Image correction with GF20-35

      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.
