Good Super Wide Angle review article

[chet]

found this article over at Nikonians and thought I'd share. It's a comparison / review of the following wide angle lenses, for Nikon bodies:

Nikkor 12-24mm f/4.0G DX AF-S
Tokina AT-X Pro 12-24mm f/4.0 DX
Tamron SP 11-18mm f/4.5-5.6 Di II
Sigma 10-20mm f/4.0-5.6 EX HSM

Interesting. I am glad I settled on the Sigma 10-20mm. I certainly got value for my money (but then I already knew that)

[chet]

thanks for that - I'll be buying a WA lens sometime soon, will take your decision on board.

Have to say that I do not agree with this review.... I carried out a similar test for a magazine in Australia I in testing two different Nikon 12-24mm lenses I discovered they were both rather soft at the wide open end of the aperture range (f4-f5.6) by comparion to the Sigma and the Tokina lenses. It was on the result of those tests that I actually went out and bought the Tokina 12-24mm (writing for a mag is a good way of testing before you buy!!). Read this review with a big pinch of salt and some consideration to the fact that no one on the Nikonians iis likely to bag the Nikon brand.

[Yi-P]

Having tested 3 of these (Nikon, Sigma, Tokina)... I havent really noticed much of a big difference in the photos out of them.

The Nikon it did have a little bit more over contrast and colour, but this is not an issue in the digital age with PP programs.

The 3 of these are all well built, not actually tank like, but very high quality finish.

Of the 3, Sigma has best resistance against flare and CA, while the Tokina fails at this, Nikon is good as well.

By far, the Sigma is half price of the Nikon and performs mostly to it, and it has 2 extra mm wide range, which makes a big difference in wide angles!

very interesting

You don't happen to have a link to an online copy of that article, do you? I'd be keen to read it.

Good point about the Nikonians!

[Greg B]

Fascinating. The Sigma 10-20 looks better and better all the time.

[Antsl]

This is the meaty part of the story writen for a magazine a while ago...

Last month our magazine managed to get hold of some of the elusive optics from Tokina, Tamron and Sigma and so we decided to road test these lenses along with their Canon and Nikon equivalents. Lenses were tested on either a Nikon D70s or a Canon 350D with most test images being made in identical conditions. Worth noting is that there can be variations in lens quality within a manufacturers run of a lens type and as we only get one sample of each lens to test we can only go with what we are presented. Treat these reviews as a useful guide but given the chance always try a lens before you buy. Here’s how the lenses compared for us!


Nikon 12-24mm f4G ED-IF AF-S DX Zoom Nikkor
The Nikon 12-24mm f4 lens offers Nikon D-SLR users the equivalent of a 18-36mm lens. Some of the advantages of this lens include the Silent Wave AF motor, G type aperture control and a constant f4 maximum aperture. A switch on the barrel of the lens allows the photographer to select between manual focus and auto focus with manual override. In a rather tricky move Nikon have also swapped the positions of the focus and the zooming rings, putting the later to the front.
Geometrically the lens has only minor barrel distortion at the 12mm setting and minimal pincushion at the 24mm setting. At the 12mm setting there is a slight softness to the image at f4 however this improves at f5.6 / f8 and is not so noticeable at the longer focal lengths. There is minimal colour fringing at the 12mm setting and none at the 24mm setting. This is a good lens for most photographic applications although the price tag may discourage some photographers.

Pros - Well-built lens, Low distortion and chromatic aberration.
Cons - Expensive, Some softness at the 12mm setting.

Canon EF-S 10-22mm f3.5-4.5 USM
Normally Canon and Nikon lenses are reasonably similar in price however this Canon lens has slotted into the market at around $700 below is Nikon equivalent. The Canon10-22mm f3.5-4.5 lens offers owners of the Canon smaller format D-SLRs (the 20D, 350D, D60 etc) the equivalent of a 16 to 35mm lens and it also offers the brightest aperture (f3.5) in its class at the short end of its zoom range.
The build quality of this lens is not as solid as some L series lenses however it is still solid enough for the demanding use of serious photographers. The lens barrel is dominated by a large zoom ring about the front half of the lens while behind it is a located a narrow manual focus ring. Manual focus with this lens is not as smooth as some other lenses in this class however it does work.
Optically this lens is one of the best in the bunch with only minor barrel distortion at the 10mm setting and very slight pincushion at the 22mm setting. Sharpness wide open is very good throughout the zoom range and although there is some minor chromatic aberration at the 10mm setting this is resolved at the 22mm setting.

Pros – Great sharpness throughout the zoom range, even at f3.5
Cons – Below average manual focus operation. Lens hood sold separately!

Tokina AT-X 124 AF Pro DX 12-24mm f4

Many photographers think Tokina only make cheap kit lenses for entry level cameras however they have also been making a pro range of optics for over twenty years. The Tokina AT-X 12-24mm f4 is the only after market lens to be released to date that offers a constant f4 aperture throughout the zoom range. The build quality is good and a slight crackle finish on the lens adds to the look; sadly though the lens lacks the ultrasonic focussing drives found in other manufacturers lenses. A clutch mechanism is fitted to the focussing ring and by pushing it forward the photographer can disengage the manual focus mode and engage AF mode. This system is quick to use although it is sometimes difficult to click back into manual mode.
Optically the Tokina ATX 12-24mm is a very good lens. Image sharpenss is very good at the 12mm setting with only slight chromatic aberration in the corners. There is slight barrel distortion at the 12mm setting however this is resolved at the 24mm setting. Although it lacks the USM motor this lens actually offers very good performance at a reasonable price.

Pros - Solid construction, Constant f4 aperture, Affordable
Cons - Clunky MF / AF select control.

Sigma 12-24mm f4.5-5.6 EX DG Aspherical
The Sigma 12-24mm F4.5-5.6 lens is unique in this line-up because it is the only lens that will give a full frame image at the 12mm setting on both D-SLR and 35mm film cameras. This lens is very big and there is hardly any taper between the 82mm lens cap and the camera mount; the front element is also rather bulbous and projects nearly a centimetre beyond its mount making it impossible to fit on conventional screw-in filters. This is the price that you have to pay though if you want to get 12mm coverage with a 35mm format camera.
Although the larger image circle should give this lens an advantage in the smaller digital format it was actually a rather average performer. At the 12mm setting it lacks sharpness, particularly in the corners and this is slow to improve as you stop down the lens. Contrast is also rather flat. At the 24mm lens the sharpness is marginally better. Of interest though was that there was no noticeable chromatic aberration in the sample we tested.

Pros – Works with both digital and 35mm format.
Cons – Large dimensions, no screw-in filter option.

Sigma 10-20mm f4-5.6 EX DC HSM
The Sigma 10-20mm lens has been much anticipated by recreational photographers for two reasons – it is affordable, dropping in at under $900 but more importantly its 10-20mm zoom range give Nikon users the equivalent of a 15-30 mm lens and Canon owners the a 16-30mm lens.
The build quality of this lens is good and the rather sleek finish is comfortable in the hand. The Sigma HSM (Hypersonic Motor) AF system is very fast and accurate and so the lens is as fast to use as its Canon and Nikon equivalents. The main disappointment is that it drops to f5.6 at the long end of the range. Optically this lens is very sharp through out the zoom range although there is some barrel distortion at the 10mm setting that progresses through to minor pincushioning at the 20mm setting.

Pros – Sleek design, very fast focussing
Cons – Minor vignetting, slight softness at the corners at 10mm range.

END OF STORY
_______________________________________________________

Worth noting is that during this testing process I actually got to compare two different Nikon 12-24mm lenses with the other lenses and both of them came of a sad second to both the Tokina lens and the Sigma. Overall thumbs up would have to go the the Canon lens but visually this lens is more comparable with the Sigma and Tokina than the Nikon. IMHO, the Nikon 12-24mm is one of the few disappointing lenses in their range at the moment. I have long been a Nikon fan however I am also able to keep objective about my equipment. Hopefully Nikon will replace this lense sooner rather than later!

[Yi-P]

How come the sigma 10-20 is f4 (constant) ??

[Greg B]

That would be a misprint Yi-P, looks like copied from the Tokina

[MHD]

So has anyone got the Sigma 10-20mm ?

What are the thoughts of people who have used it? Price certainly is right!

[Nnnnsic]

Scott, I've seen some images of it on a Canon and it certainly looks good.

[Alpha_7]

So has anyone got the Sigma 10-20mm ?

What are the thoughts of people who have used it? Price certainly is right!

Scott I've got one, and I"m more then happy with it and the images it produces. I have to admit that since I got my 50 1.4 it has hardly left my camera so the 10-20 is feeling a little lonely right now, but for those WA shots it has served me brilliantly.

[MHD]

sample?

[Alpha_7]

sample?

I haven't posted too many of my own WA shots, but I'll dig some up and post them when I have a minute, I'd do a quick search for Pharmer's shots, he produced some gorgeous images with the 10-20 before he upgraded it with the Nikon 12-24.

My shots don't do the lens justice I feel, I'd suggest looking at Barrie (Pharmers shots).

[MHD]

So by that you infer that the 12-24 is a superior lens?

[Alpha_7]

So by that you infer that the 12-24 is a superior lens?

He used the word "upgrade", he got a chance at a second hand 12-24 and swapped lens, you'd have to ask him now if he's happy with his choice.
For me I couldn't justify the price hike for constant f4, and perhaps alittle more sharpness.

[MHD]

Price hike? Price doubling more like it...

Also I wonder why the 10-20 is so much cheaper than the 12-24 which, in reviews seems to fare a lot worse

[Glen]

If you mean Sigma 12-24, maybe because the 12-24 is the only full frame one in that range

[MHD]

Ahh... that would be it...

Well, anyone else with an opinion... all the reviews are pretty good...

And even better I have been given the official OK

[MHD]

ooh... or I could get the sb-800....

I have the sb-80dx at the moment, which is little better than a manual flash...

[Glen]

Scott, work out where you are going to be most in the next few months, outside or inside? If I remember right you are going to Canada, that would swing me to wide angle

[MHD]

And that, Glen, is prescisely the problem...
I want a WA lens, it will be an ideal addition for canada...
But my current flash does need upgrading...

[Glen]

But my current flash does need upgrading...

and so does your current wide angle ie none

Good luck, these decisions are never easy

[Yi-P]

Scott,

My samples from the Sigma 10-20

Its a very wide angle lens, and it takes some more learning to use for it, and im still at this way.

----

----

Im open to your questions about the lens if needed

[MHD]

Very very nice...
Only one question: Any regrets about buying it?

[Yi-P]

Only one question: Any regrets about buying it?

Maybe one, not enough skills to use it properly...

[ABG]

Scott,

Craig was kind enough to loan me his 10-20 while we walked around Circular Quay and The Rocks. I was most impressed with the sharpness of the images it produced. The FOV at the wide end is mind boggling. In terms of value for money, it is simply outstanding. The only niggles I would throw at it are some slight softness in the corners (but you really need to be looking for it to notice) and it is quite slow (f4 from memory) - you wouldn't want to buy it if you were looking at taking lots of low light level photography.

[Yi-P]

Being slow, but on a short focal length, does it matter that much?


At 10mm, you can handhold it at near 1/2" @f/4 exposure!

Is that slow??

[ABG]

My hands aren't that steady Yi-P. Your point certainly has some validity, but most of us struggle with any non VR or IS lens below 1/30, regardless of focal length. Well I do, and with a sample size of 1, that makes most of us

[MHD]

You will not find VR on a lens that wide...

Well I think I am decided..
Helllooooooo Poon!

[mark]

So by that you infer that the 12-24 is a superior lens?

MHD - I purchased Barrie's old Sigma 10-20 and love it. Like Yi-P my only regret is that it's a better lens than I am photographer.
