[NOT GOOD for UV] Samyang 14mm f/2.8


Recommended Posts

Here is a simple test of how the Samyang 14mm f/2.8 works with a Baader U. This lens is an ultra-wideangle (rectilinear) lens for full frame – on an APS-C sensor it is not so exciting.

 

The two images are WBed as for a Focotar-2: I was not able to do a custom WB for the Samyang shot using RawTherapee as RawTherape was reporting no green channel.

 

The shot using the Samyang required about 40x the exposure for the Focotar-2.

The difference is obvious. The Samyang shot is much more monochromatic indicating that it is passing only a part of the UV range that the Focotar-2 passes.

 

So I would conclude that the Samyang 14mm is not really suitable for UV photography. (Not surprising as it has 14 elements in 10 groups.)

Bernard, given that this is not a technical assessment (like your other work) of the Samyang 14/2.8, I am not sure this is the place for it.

Indeed. A 14/2.8 that was UV-capable would have been epic news.

 

Such a lens would make for a very beautiful Christmas present :grin: I've tried the Walimex-version some time ago and got a similar result.
