Sigma 18-35 f/1.8
04/18/2013 12:00:56 PM · #2
Hot diggity! That's a sweet lookin lens!

Sounds sweet. My Canon 18-135 is my most often used lens. I would expect a constant F1.8 will be just a little pricey in comparison to my Canon. I'll have to keep an eye on it, though.

Oh, I misread that. It's an 18-35. That makes a lot more sense.

My guess is that a constant 1.8 is going to be $$$$

Probably so. The lens is also 2 pounds. But if it's between buying this lens and spending the $$$$ to upgrade your entire lens collection because you just went full frame, this could be a good option.

When I went to full frame, the camera body was the cheap part. Reconciling my lens collection cost real money.

? This is APS-C only - you'll find it quite useless on a full-frame body - this makes me happy I've kept my APS-C bodies, since even at 1.6x crop, 18 is still pretty wide. The only thing I really wish it had is IS, that may seem silly at f/1.8, but that's only until you try to shoot in twilight with it.

i'm trying to understand the point of this lens...

you can buy a 1.8 primes, do you really need a 2lb zoom in that small range?

Thing has 5 SLD elements and 4 aspherical elements. That has got to be spendy, even with the smaller crop sized glass.

The last few Siggys have been absolutely stellar lenses. If this turns out to be an optical masterpiece like them, Canon and Nikon are going to have to step up their game.

Does anyone even make a 1.8 prime as wide as 18mm? Also, by the time you stack all these fast primes in your bag you might end up with 2 lbs worth of lenses anyway. And you probably spent well over what this thing will cost (which is probably already significant).

Primes and zooms can coexist.

you can get a 24mm/1.4 but it is pricy and probably heavy. others at 2.8 for cheaper and lighter.

do you need a 1.8 18mm? one would think 2.8 would be plenty. maybe i don't understand the 1.8 in such a wide lens, it cant be DOF control that wide.

im sure sure there is a market for it or these or else they wouldn't have made it, im just asking the question of what the purpose is because i don't see it.

The widest 1.8 or faster prime is a 1.9 pound, $629 20mm f/1.8 Sigma. The widest fast Nikon is a 1.4 pound, $2200 24mm f/1.4.

If you're an event shooter that has a crop sensor camera, this could be a godsend.
04/18/2013 01:37:39 PM · #12
You are right, I don't think the DOF would matter much at 18mm. For me it's more about the speed than the DOF. At 1.8 you can more then double your shutter speed compared to 2.8, without sacrificing ISO.

Not that it matters, I don't think I could afford whatever this beast is going to cost :)

I want one.........droooooollll

Remember that in FF terms, this is the equivalent of a 27-52mm f/2.7. If you're comparing to FF, those crop sensor 2.8 zooms (which are also heavy and expensive) are the equivalent of an f/4 lens on FF. For DOF control, a 1.8 could indeed be useful.

I think the main point of this lens is that the big guys have pretty much given up on creating professional quality lenses for crop sensor cameras, because they're busy trying to push the high end to FF. But the majority of the market still uses crop sensor cameras. If this is a good lens for anything resembling a competitive price, this could capture a big part of that market.

If I understand it correctly, Sigma is releasing this lens as a part of a new line the "Art Series", which will be lenses designed to really go outside the realm of "normal" lenses in a big way - the idea is to enable people to create more artistic photographs, something like a midpoint between lensbaby lenses and regular glass - the expectation is that the optics should be quite good, and I think we at DPC will see this series become pretty popular within our ranks.

I notice Pentax has been left out of the recent new Sigmas. But then we have all the old Pentax lenses. And then again there is the recent Ricoh Pentax marriage which has already spawned an awesome child.

I don't have any of them (yet), but Sigma has been hitting some real home runs lately with some of their Art Series lenses. The 35mm f/1.4 is apparently amazing, and it's half the price of the equivalent Nikon.

Yeah, and even before the art series came out, their primes had DRASTICALLY improved over their previous iterations. Their 85 1.4 was pretty well regarded, as was the 50 1.4 and 30 1.4.
Of note is that they also had a very quick turn around and very cheap repair for any services, at least in the Lensrental sampling.

ETA: I have the 30 1.4 and enjoy it. The focus is generally good, but does have a specific weird issue that takes a bit to actually describe in words.
