Best wide angle lens for K-1?

being a full frame lens and thus giving me the resolution I want was the reason for me to buy the samyang 20mm.
The difference betwenn the samyang in full resolution, the samyang downscaled to APS-C and the DA 15mm in crop mode can be seen here.

samyang-full-center | spam123 onetwothree | Flickr

Sorry for not having a more sophisticated comparison here, but I simply did not have the time to test the samyang as much as I liked to. But I guess these pics show some important facts. However, for me its time for my well deserved vacation (I have both lenses with me ;-), see you again in December.

concerning flare, here are the obvious results:

the da 15mm is simply unbeatable. While the samyang star bursts are beautiful, I find the da 15mm star burst stunning.

exactly my thoughts. My flight tomorrow is with the samyang 1.8, will use it when applicable because its full frame, however, the DA 15mm limited is with me and will be for pics against light or where I have the feeling that the DA will deliver the extra pixie dust.

from my first test it is a good lens, however, the flare resistance of my DA 15mm limited is just not reached by any lens I have worked with. I hope Pentax brings us a smaller packaged (compared to the samyang) 20mm-ish lens with the sharpness of the samyang and the flare-resistance of the DA 15mm limited

I would suggest darktable in any way, it's great software. Additionally, it's free, open source and respects your privacy. No more to say.

I can fully understand this! The story of my Samyang copy is fun: I contacted the manufacturer, they told me that they don't know when the first shipment would arrive in November, but told me it is for sure not before November 3 (the day my flight is booked for my well deserved vacation). However, they gave me the contact of the main distributor in Europe, and they also told me that it's not available. However, on a famous price comparing portal in Austria, the lens was listed, but only with one reseller in Germany. I just contacted them (Ihr Spezialist im Fotosektor | Digitfoto.de) because I thought this was a mistake - officially there is no single copy in Europe yet - and they told me they have it on stock. Now I have this lens.

My first impression is: wow! Seems like it's quite resistant to flare and very sharp. However, it's by far not as pocketable as the M20 f/4. Details will follow...

I just got my Samyang 20mm f/1.8. Lucky me I will have time in November to go for my passion photography much more than the last months. I will do a short non-scientific comparison between the Samyang 20mm, the smc Pentax M20 mm f/4, the DA* 15mm limited in crop mode and the smc FA* 24mm f/2, will post my findings here as soon as I have time and the weather is OK again in Austria for a hike.

where are the k-mount lenses? Even Fuji manages to bring 6 MF lenses with their announcement. With Sigma announcing again some great lenses but not for K-mount I do really want some _new_ lenses, especially primes, be it f/4 for smaller size or f/1.4 for speed :-/.

hmm, here is a 100% of a pixelshift jpg out of cam: Pasteboard ? Uploaded Image
this one is produced by dcrawps: Pasteboard ? Uploaded Image

I have not edited any pixelshift images so far because I refuse to use spyware operating systems and so there is no software that I could use so far.

hm, seems like dcrawps does only use one DNG file (of the large DNG file containing actually 4 files). The result is by far not as sharp as I get out of cam (no sharpness tweaks so far, just the standard settings).

THANK god someone listened to my whining/dreaming about a 20mm lens. One cannot have everything (slower but more lightweight lens), but 500g is the upper limit for me if image quality is right, so I hope this lens delivers. With 7 blades I will probably get my beloved DA-15mm-limited-like stars from light sources. I will keep my fingers crossed for a stunning lens.

I would love to see some comparisons, especially edge sharpness, are there any owners of both M20 f/4 and the new dfa 15-30? ... If the latter was an f/4 or even an f/5.6 lens I would buy it in a hearbeat, I just don't need the weight of an UW-f/2.8 zoom and I am still not convinced that the dfa is worth the money compared to my M20 I already own.

I do have a FA* 24mm f/2 and a M 20mm f/4. Both great lenses, but when I want to go wider than 31mm I want the 20mm, color and contrast is great, but it lacks sharpness in the edges and the stars from light sources are not as beautiful as from my DA 15mm or my FA 31mm. I just don't get it that there is no modern f/4-ish 20mm-ish with stunning image quality on the roadmap. The 15-30mm is optically probably what I want, but that is another kilo to carry.

this is from the M20/4. with crops each. By the way: the reflecting star (which I really like, its similar to my DA 15mm ltd.) is the Red Bull headquarters in Fuschl, Austria.

this is out of cam. 1st one is pixelshift of 31mm + PL filter with an 100% crop attached. 2nd is with the DFA 100mm macro (little movement due to wind). 3rd is pixelshift of DA* 55mm with PL filter. I love the results.

Hehe, seems like a nice lense. I need something with more reacht as the FA* 200mm + 1.7 AFA, would love to have the new Sigma 150-600 but they don't offer it in PK mount unfortunately. I am still not quite sure whether to buy the new DFA 150-450 or the Sigma 50-500 ... but since I don't have money to spare at the moment I may not waste my time on thinking about those :-)

Did I already mention that I love this cam? Went out with the FA* 200mm + AFA 1.7, the DA 100mm limited macro, the FA 31mm limited, the Meyer-Görlitz Telemegor 180/5.5.

Exif should be OK on the links, IIRC the dragonfly was shot with the macro, the yellow flowers with the telemegor, the shot of the park with the 31 and the rest with the FA* 200mm + AFA 1.7. Attached a 100% crop of the heron in flight.
AF on the camera is great, BIF is possible even with the above combo. Pics are all out of cam, the FA* + AFA would need more sharpening, I guess there are better tele-solutions out for the K1 although I really like it and I think the results are better than with the DA 55-300 in crop mode.
