I've had this lens a while but haven't used it too much, yesterday I went to take photos in Cardiff with my new 60D, I recently sold my Sigma 18-50mm AF lens in order to get the newer OS version so it turned out the only wide lens I had available was the Samyang
But it's not bad at all, the only cause for frustration was the distortion but then again sometimes it can help to give a dramatic effect.
I didn't use it wide open but between F/5.6 and F/10 and I found it was pretty sharp at these apertures. The colour and contrast were very good too.
It's quite well built and I think it performs quite well on the 18mp sensor.

indeed beautiful images, the colours are good. i especially like the second one. but the "starbursts" of the lights look a bit odd, most of the bursts i have seen seem to converge while this lens renders them the other way around. i think i like it this way better actually. i feel like it makes more sense this way |

They are all converted from raw but I always use the same settings regardless of lens, I would say the colour is about the same as the standard jpeg setting on the camera with the contrast being slightly less.
I used to shoot simultaneous jpeg and raw for a while until I could make the raws look better than the jpegs.
I usually convert with capture one after doing the levels and adjusting the white balance to how things looked to my eyes if necessary, then I have an action that automatically tweaks the curves and adds +5 saturation and +10 contrast in photoshop, I find this gives nice punchy images that are still on the right side of overdone.
If I compare a converted raw to a jpeg from the camera the colour saturation is about the same apart from being slightly colder but the contrast is usually pushed too far causing blown highlights and colour channels.
EDIT: I forgot to add, I think the lovely late evening sun has a lot to do with the colours as well! _________________ - Dave

It's the same lens as NikonD posted a photo of.
All of these 18-28mm lenses are made by Samyang as far as I know, there are subtle differences such as the rubber grips and I have heard of some that have less metal and more plastic but they are basically all the same. Some brands exaggerate the specs a little such as the Vivitar version which is labelled as a 17-28mm _________________ - Dave

I've got this lens for cheap, but it is canon mount, so if decide to use, have to rework to sony mount, which might require quite large efforts. I already have Tamron 17-50/2.8 AF LD Di XR SP (and so on) for my SLT-A57. So how you can tell, is this lens comparable in terms of sharpness and CA to my tamron or not? _________________ I have nothing to compensate with lens |

This Samyang made lens is notorious. It is available under many different brands and is generally considered abysmal. I had a copy and it was quite useless, being very soft even well stopped down. The only decent pictures I can remember seeing from this lens are from the OP in this thread. Basically, it has zero chance of outperforming your Tamron. Don't waste your time adapting it. Just throw it away. _________________ Olympus OM-D E-M1 for everything |

I used to have one of these back in the early 90's (Pentax mount) and mine was probably comparable to the OP's i.e sharp-ish if you stopped it down a bit, however, bear in mind this was an extreme wide angle zoom that retailed for the same sort of money as a the plastic Tamron 28-70mm f/3.5-4.5 of the same period and well under half the price of a contemporaries like Tamron 17/3.5 or Sigma's 21-35mm.
Would I but one now? No, but it was an amazing intro to ultra-wide photography when I was an impoverished Architecture student and built like a tank. _________________ Canon + Contax + Minolta + Nikon + Olympus + Pentax + Yashica = Adaptall-2 |

I have one too. Got it some years ago (Kalimar brand) very cheap in PK/A mount.
Biggest problem with it is its just not sharp, even in the center, even stopped down to f/8.
Color isn't bad and flare is OK, and distortion isn't much worse than most old superwides costing much more. Overall impression of its output is respectable. Just don't zoom in.
Its not a bad lens for web resolution and quite useful on APS-C.
It does go significantly wider than the usual digital kit lenses, in spite of the specs.
With B&W 35mm film it is an interesting special effects lens, and cheap to play with. On film cameras 18mm is very wide indeed.
If someone is on an extreme budget I can see it as a fun option. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |
