Sigma 14/1.8 - why I like fast ultrawides - JJ_SO - 10-16-2017 This very beautiful weekend in autumn I took my old 14-24/2.8 Nikkor and the much less older Sigma 14/1.8 Art with me to try and see what happens to both in front- and sidelight. I knew the Nikkor is not good in handling flares, what i didn't know was, "is the Sigma although wider open, better in avoiding flares?" It's no problem to provoke the Sigma showing bits of flare. These are just not as rainbow-colours as the one from the Nikkor. This kind of flares I find hard to deal with in post production. 1 ½ stop faster and less issues at f/5.6, cool. But that's only one bonus (and to be expected from a prime this size and weight) The other is the combination "close-up, wide open" Sigma 14/1.8 - why I like fast ultrawides - JJ_SO - 10-16-2017 ... to be continued This one was wide open at f/2 Here's a crop: What I like with this kind of lenses is the possibility to show a hint of a lot of background and melt it away in nice blur, while something pops out of the picture just because it's much sharper than the rest. Like this foliage - the colours would be enough Sigma 14/1.8 - why I like fast ultrawides - JJ_SO - 10-16-2017 ... and the third and last one Again f/1.8 And the last one is a focus stack, handheld at f/2.5 It's not perfect, parts of it I should have cleaned better - but I was amazed that I just could sit next to the rail, keep the camera sort of steady and start a 30 frames focus stack. Sigma 14/1.8 - why I like fast ultrawides - davidmanze - 10-17-2017 Nice shots through the leaves at sunset JoJu!......... I will have to do a comparison with my Samyang 14mm F2.8 to see how the lens performs bokeh wise, as soon as my D750 comes back from Nikon for the shutter recall..... ...........though I will say that the third and fourth image bokeh look somewhat busy..... Sigma 14/1.8 - why I like fast ultrawides - JJ_SO - 10-17-2017 Actually, bokeh is not a gaussian blurr to even out all nervousness It was a field with a lot of different plants and a lot more bees, so these were beesy to do nervous bokeh :lol: Sigma 14/1.8 - why I like fast ultrawides - davidmanze - 10-17-2017 Ah!! got it.... .........busy bees............busy bokeh! Sigma 14/1.8 - why I like fast ultrawides - JJ_SO - 10-17-2017 Yeaaah, that's how we do in showbeeeeezness ^_^ Sigma 14/1.8 - why I like fast ultrawides - obican - 10-17-2017 Some really nice shots, JoJu. I love wide open close up with ultrawides. The 30 shot focus stack is a clear demonstration how useful is to have such gimmicks easily accessible from the camera body too. Now you know you can get away with a quick and dirty stack so you won't refrain from it the next time you see an opportunity. Good to know . Sigma 14/1.8 - why I like fast ultrawides - JJ_SO - 10-17-2017 I came home with 4 stacks: 10, 20, 30, 40* pictures each. That's the thing with unfinished (imo) software-options: A finished option would ask me "tap closest distance" ok "tap farest distance" - ok, "with aperture f/2.5 you need 28 shots. Push shutter release to start."
All the menu options come in landscape orientation. Going to portrait orientation = turn head 90°. Yawn... Nikon, just look at PhaseOne, they do know their stuff. But you're right, it's such an advantage to have this kind of DoF enlargement onboard. *10 being not enough, I guessed 20 - also not enough, then I had the glorious idea to check the distance scale. With 30 shots, it ended up close to ∞, but I did a 40 shot row just to be sure. 30 were enough. I think it took a bit too long to find out. Next year with Arsenal I gonna see if they have a better usability concept. At least, they merge the stack in-camera, if i want. Thanks for the compliment, wide open at close distance still is not overly in use. It's worth to face the challenge of focusing. Sigma 14/1.8 - why I like fast ultrawides - obican - 10-17-2017 Had made one just yesterday. Missed the critical focus though, should've stopped down slightly or actually checked the shot before eating the rest of the subject . [ATTACHMENT NOT FOUND] This was a lucky shot that came out of nowhere. I was there, shooting some trees until my friend noticed what's on those trees. Took a bite, noticed how cute it looks, made a shot to send to the gf, noticed how good the shot turned out but only after subject was fully consumed. |
