I stopped by the local camera store a few days ago just to poke around, and to my surprise they had the 18-35! I returned this morning with my camera bag with the hopes of being able to do a comparison (physically only, since it was a Canon mount). In no way shape or form is this meant to be a review, however for those on the fence of pre-ordering (I still haven't made the plunge but I am
*VERY* seriously considering it right now), here are my first impressions:
- AUTOFOCUS: Super quick on the Canon 700D (which the store owner let me play with, and I must say - wow...the Chinese plastic is strong with that one), although with such a short focus throw (it's 18-35mm), it isn't expected to be too slow. The DA*16-50 was only a bit slower although the 18-35 was obviously the winner. No focus accuracy issues I saw, but I only played with it for maybe 10 minutes.
- AF/MF SWITCH: Without any question the toughest switch to activate of any lens I've ever tried. The sound is a very *sharp* click. Very sharp. I like it, and there is NEVER any chance of it accidentally being switched to MF or AF without you consciously doing so.
- WEIGHT: This baby is heavy. Made the 700D a bit front heavy, but I think with the Pentax K-5 it would be a perfect balance. Heavier than the 16-50, although when I picked them up one in each hand, it didn't seem to be too far off. According to B&H the difference is quite a bit - 565g vs 811g, but in the hand the difference appeared much closer. Must be because I've been working out, though, huh?
- SIZE: It's not small. It is taller than the DA* 16-50 and even taller than the Sigma 8-16. Below are photos for reference. But it isn't fat, which I was expecting for an f/1.8 zoom lens. Granted "fat" is relative, but I expected it to have a bit more girth.
- BUILD: The build quality is beautiful. Super tight tolerances and a beautiful finish. Yes it's mostly plastic and rubber, but there's nothing cheap about it, except maybe the rear lens cap (I hate Sigma's caps - the epitome of cheap).
- ZOOM AND FOCUS RINGS: The tightest rings I've ever felt on a lens, but in no way in a bad way. Beautifully damped and again, the super tight tolerances are apparent here. Makes me think if you put a rubber o-ring on the mount it might be weather sealed. Honestly... Also, I noticed that the zoom ring "zooms" in the same direction as Pentax lenses, however the focus ring is in the opposite direction. I didn't notice it until today, but my Sigma 8-16 is the same way, so I guess it would be safe to say that you won't find that a hindrance
- FRONT LENS OBJECTIVE/GLASS: It is bulbous, but not much. No where near as much as a fisheye or the Sigma 8-16, but it is far more bulbous than any standard rectilinear I've ever seen. Not an issue, but I did notice it.
- LENS HOOD: A super tight to screw on for both regular and reversed on the lens. I liked the grip along the edge of the hood's widest part - nice touch. Still no CPL window that is standard among Pentax's lens hoods though! I also liked that it was narrower to the body when reversed, something the DA 12-24 and the DA* 16-50 could learn a lot from...
Here are photos I took. From left to right, also with their focusing windows so you can see what I meant by the direction of travel. The store owner was very nice to let me use a DA 16-45 he had on the shelf because I didn't have anything wide enough to get all of them in the same shot from so close
DA* 55, Sigma 8-16, Sigma 18-35, DA* 16-50, FA 77 LTD, K-30
A top down look with the Sigma 8-16 to show its size when mounted. I lined up the Sigma 8-16 and its cap to mimick the exact placement of when mounted as well.
Each of these are different shots, all at f/1.8 with their 100% crops included, no sharpening applied - the only processing was RAW into Lightroom with slight exposure fixes - nothing more. Canon 700D. Keep in mind that glare also is a bit of an issue with reducing sharpness because they are through glass windows with a lot of overhead store lights. Also there is a bit of noise because I didn't get a chance to change the ISO. I had a hard enough time changing settings. I settled for Av mode and RAW (which was another pain to try to change - whomever claims Canon's menus are superior to Pentax's is out of their damn minds).
Focus about 2.5m away
18mm
35mm
Focus about 10m away
18mm
35mm
Close focus, about .5m away.
Super shallow DOF at close distance.
My biggest gripe -
I would have preferred if they made it 16-30 f/1.8, but that won't change the fact I will most likely get it sometime around Christmas time after seeing some comparisons against the FA 31 and maybe even the Sigma 30 f/1.4 ART (not the old version) should Sigma decide to release it for Pentax.
If the lens were weather sealed, though, I'd have one on pre-order to replace the DA* 16-50.
Like I said - this is *not* a review at all, just a hands on for a lens that most haven't seen in person yet. With that in mind, I hope this was beneficial to you
