Normally, I dislike seeking opinions on This vs That, because I figure one should do their own research and not "outsource their brain" on such matters. However, on this one I've done my research and I'm still torn. I would be using this lens for night sky stuff (aurora, meteors, mostly). I live at 41N latitude so normally my Sigma 30mm f/1.4 is what I will use, but the recent aurora outburst surprised me by surpassing the FOV I have with that lens. I don't want to get caught in that situation again.
I have a Sigma EX 10-20mm f4-5.6 that I happily use for daytime ultrawide, but it is possible that this new lens would ALSO have use in that scenario in lowlight also. (I like to do severe storm photography and it often gets very dark under them, even in daylight hours.) So that usage is of secondary concern, but for THAT I would definitely prefer the extra wide FOV of the 14mm over the 16mm. It appears that the 14mm outperforms the 16mm in CA: 16mm: http://www.ephotozine.com/articles/samyang-16mm-f-2-0-ed-as-umc-cs-lens-review-22335/images/highres-Samyang16mmCA_1373266588.jpg 14mm: http://www.ephotozine.com/articles/samyang-14mm-f-2-8-ed-as-if-umc-lens-review-19621/images/highres-Samyang14mmCA_1341302313.jpg But on resolution, the 16mm seems to outperform the 14mm (and I shoot on a K-3) 16mm:http://www.ephotozine.com/articles/samyang-16mm-f-2-0-ed-as-umc-cs-lens-review-22335/images/highres-Samyang16mmMTF_1373266691.jpg 14mm:http://www.ephotozine.com/articles/samyang-14mm-f-2-8-ed-as-if-umc-lens-review-19621/images/highres-Samyang14mmMTF_1341302315.jpg However, with aurora, a shorter exposure is more important than resolution because the longer you leave the shutter open the less resolution you are going to get with the aurora "motion". So the f/2 would be advantageous. Anyone with Real World experience with one or the other? At this point, I'm leaning slightly towards the 16mm f/2 -- Life is too short to put up with bad bokeh. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
