Pros: Fast, sharp, CA well controlled, beautiful color rendition
Cons: vignetting, coma at f/2.0, distortion

Bought this lens last year for astrophotography mainly and was very pleased with the results. I have the DA*16-50 but for astro work it was just not good enough at 16 mm f/2.8 so I decided to get the Samyang to remedy the situation. The thing I like about this lens is its ability to render the different colors of the Milky Way, something my old M or A lenses cannot do very well for lack of ED elements I suppose. Very usable wide opened like in my first picture here. The picture shows noticable coma in the corners but not so bad. Lots of people overlook this lens and go for the full frame 14 mm F2.8 but if you know you're going to stick with aps-c this lens offers f/2.0 which brings in twice as more light as the F2.8. It also offers 8 mm clear aperture against 5 mm for the 14 mm and that means more stars will be recorded as well.

I also enjoy it for general use on landscapes as focus is easy and precise but here of course the 16-50 is a lot more versatile and as sharp if not sharper from f/4 up.

Pros: Super sharp from f2.0
Cons: A big lens compared to many new and old pentax lenses
Sharpness: 10    Aberrations: 10    Bokeh: 10    Handling: 9    Value: 10    Camera Used: K3   

I am very impressed with this lens. It is sharp at f2.0 but a bit dark in the corners (not too dark, but sometimes it needs to be corrected). No problems with dark corners at f2.8.
It is surprisingly useful as a walk-around lens for tourists and for close-ups.
I tried the 15mm limited and liked the size and construction very much, but not the sharpness. The 16mm is larger and has no auto-focus, but the sharpness and fast aperture makes it a much better lens for me. I have never been this satisfied with a lens.

Pros: Sharp, Colourful, , low CA, Fast
Cons: Big and Heavy, Manual Focus
Sharpness: 10    Aberrations: 10    Bokeh: 6    Handling: 8    Value: 10    Camera Used: Pentax K-5   

This lens is very underrated, even among people who like Samyang-products. At first I asked myself, why I would need a fast wide lens? I mean you mostly need the dof with wide shots so you stop the lens down anyway, right? Well, not necessarily. This lens is perfectly sharp at f 2,0 and it gives you a lot more options than a normal wide-angle lens would do. You can shoot people in their environment and get a fantastic 3D-look. But it also works well for architecture r landscape. It is a bit heavy but for me the IQ is worth it.

Picked this lens so i could get good Milky Way/Astro Photos. Great lens for landscapes. Nice and sharp. Built solid. Here are some samples taken with it and a K-30 https://www.flickr.com/photos/millermagic/16019644342/

I've been looking long for the perfect 24mm equivalent lens, which translates to around 16mm on APS-C. As such I've gone through quite a large collection of lenses, some of which I still own:
- Vivitar 24/2.8 (retired, living in a box): on my old SFXn, the lens that made me love the FoV
- DA16-45/4 (sold): bought with my *istDS because of the 16mm wide end. Very nice lens, but I didn't like it extended at 16mm which was the end I mostly used it at.
- Zenitar 16/2.8 (sold): mild fish eye, but my first cheap solution for a compact wide angle prime, not enough resolution beyond the *istDS's 6MP though.
- DA10-17: replaced the Z16 as a more flexible fisheye, but never as a 16mm replacement really. Still use it from time to time for shooting straight up (only situation where I prefer fish eye effect to rectilinear).
- DA*16-50/2.8: replacement for the DA16-45 because of AW, not extending at 16mm, f/2.8. Didn't like the distortion at 16mm and lack of sharpness wide open, but could live with it thanks to LR's lens corrections and stopping down slightly. Still is my standard workhorse regardless.
- DA15/4 limited: replaced the Z16 as my preferred wide prime after a long search (dismissing the DA14/2.8 after trying it for a day). Love the size, luke warm about the lens cap though, and because of the integrated hood cannot take filters larger than 49mm (unless using a spacer between lens and step down ring). Shame about f/4 but that's tradeoff for size. I still love this lens, but it's not for wide open use and its corners could be sharper... Adore this one as a street photography lens in town.
- Sigma 8-16: odd one out: Excellent for ultra wide with a decent 16mm long end to cover my fav FoV. Actually better at 16mm than the DA*16-50/2.8 IMHO. Large and heavy and no possibility for filters... My UWA workhorse nevertheless.

That's a long list isn't it? Why did I bother to get the Samyang 16/2 then? For all the reasons the others weren't perfect really:
- It's large but not too large.
- It's great at f/2. Of course it improves stopped down, but the contrast between in-focus sharpness and out-of-focus bokeh allows for very 3D results in close focus situations. For wide open use focused near infinity it beats all the others easily.
- Very sharp stopped down, and thus over the entire APS-C frame.
- Distortion, aberrations, vignetting are under control, esp compared to most of the others IMHO.
- I love the feeling of this lens. The focusing ring is a pleasure to use. Very good grip and well dampened.
- It takes the 77mm filters that I have for my DA*16-50/2.8 (ND & IR).

Cons: (none of these are a major issue though)
- Hood is a bit flimsy compared to the build quality of the lens itself.
- It's possible to focus beyond infinity, which may add a challenge when using this lens for night landscape photography, one of the applications I intend to use it for. But I know I have to pay attention to this, that should avoid surprises.
- You do need more time to get a shot because of the manual focus, esp when using it wide open and Live View is actually the best way to nail focus.

What will the Samyang 16/2 do for me?
- Allow me to use the lovely DA20-40 as a standard zoom more often (instead of the DA*16-50/2.8). The DA15/4 complemented that one already, but the Samyang 16/2 will be better (more universal) at this.
- Give me more light and sharpness for night landscapes. I really look forward to using it for this.
- Bokeh at 16mm!! Finally I won't have to do bokehramas as frequently to get some bokeh in my wide shots.
- Not tested yet, but I would like to see how this one does with IR (hand held at f/2?) and long exposures.

hth, Wim

Pros: Sharp - sharp wide open, smooth & very close focus ability, takes filters, great focal length for APS-C
Cons: 1. The front cap is flimsy and comes off unintentionally - FYI. 2. Focus goes past infinity (common with Sammy lenses) so it's a lil bit more trouble to use in the dark.
Sharpness: 9    Aberrations: 8    Bokeh: 7    Handling: 9    Value: 10    Camera Used: K-01   

My copy is impressively sharp right at f/2.0 and cuts night time exposures in half (at least!).
Even though a wide angle, at f/2 focus needs to be spot-on for really good results.

Two things I don't like:
1. The front cap is flimsy and comes off unintentionally - FYI.
2. Focus goes past infinity (common with Sammy lenses) so it's a lil bit more trouble to use in the dark.

This is a really great value if you find it on sale below $300!

Pros: very sharp; nice colours; close focus
Cons:
Sharpness: 9    Aberrations: 9    Bokeh: 9    Handling: 9    Value: 10    Camera Used: K5IIs   

This is again a TOP lens (I also have the 8mm and 24 mm) and I like this 16mm SY a lot. It can be used for both close focus and Landscape.

I do use the Live View a lot (and info button to zoom in); this makes it easier to ensure the right focus of objects and DOF. I also use the KatzEye; with some practice the sharpness/focus will be spot on.

some examples:

Pros: Good Sharpness Wide Open, Fast, Cheap
Cons: Getting A Good Copy
Sharpness: 9    Aberrations: 8    Bokeh: 9    Handling: 8    Value: 9   

First copy I received appeared excellent at first, but further tests revealed decentering. This manifested itself as uneven vignetting wide open and severe distortion in the upper right corner or the frame. Stopping down helped, but distortion was unacceptable. If this lens did not suffer from the decentering defect I would give it a 10, but as this is probably common, I would suggest 8 or 9. Even with the defects found it is a usable lens in many applications where the one particular corner can be managed. I returned the lens to B&H, which was cheerfully exchanged.

Evaluation of the second copy revealed good sharpness overall. Vignetting at f/2 is noticeable, but gone by f/2.8. Colors are punchy and vivid. Bokeh on close-ups is very good, with very thin DOF.

The lens does exhibit coma in the frame corners, especially wide open. A concern for astrophotographers, but stopped down to f/2,8 produces a nice flat field with very little vignetting and tolerable coma. See "first light" images below. Pleasing images at f/2.8 straight out of my K-5 IIs.

16mm is the perfect focal length for video. I use this on my k-01 and it really shines.
