Hi all, I am interested in getting a t3i soon and want to know if this is the only affordable t3i wide angle lens on the market: http://www.amazon.com …F8&qid=13142845​16&sr=8-19 (external link)

are there any better options? Also, I am a bit confused on the focal length of these lenses, for example the kit lens will come with an 18-55mm IS lens, so won't that have the same capability as the stand alone canon 24mm wide angle lens? I am sure I am wrong on this though since that stand alone 24mm canon lens is $366..

I would really appreciate somebody to educate me a bit on these lenses. I also plan to get the 55-250 IS for telephoto. Lastly, will that sigma or other lenses you recommend be okay for video as long as they are on a tripod.

Thanks!

Why are you in a rush to get an ultrawide lens? The kit lens covers a moderately wide angle at 18mm. Why not start with that lens and see if it is wide enough for your purposes?

Anyhow, the Sigma 10-20 is a decent lens for a fairly reasonable price. There are better ultrawides like the Tokina 11-16 or the Canon 10-22, but they both cost a fair bit more.

Not all lenses at a given focal length are created equal. So, to answer your question about the kit lens vs. the 24mm prime, no it will not have the same capability. It will cover the 24mm focal length, yes, but it will be much slower and the image quality will differ (I'm not going to debate better/worse here). I suggest you read up on some of the basics of aperture, f-stops, shutter speed, ISO, etc. The book Understanding Exposure is a great reference.

Pretty much any lens is "okay" for video. Just as with stills, it all depends on what your goals are.

Do a little research and consider a nice used Tokina 11-16/f2.8 since it has been a very popular wide angle since its initial release and still hard to find new due to the earthquake i assume.

consider a prime like the sigma 15mm f/2.8 fisheye. It will give you a substantial changeup from your 18-whatever kit lens with excellent quality. The wide angle zooms generally overlap with the bottom half of many of the normal zooms, so I don't see much point in a zoom in the wide range. A prime will also be lighter.

thanks park, I will definitely wait to see the range I get with the kit, but I have been seeing many wide angle photos lately and love the dramatic look of them, especially for beautiful scenic shots of mountains and the outdoors.. heck even wide shots of objects like cars seem really cool as they sort of "suck" you in. I plan to make videos and just wanted different lens options so that the whole movie doesn't look like a "homemade" movie..

There are a alot of landscape photos that look great but try to see if you can see the EXIF data and it should tell you the focal length. You will be surprise how many are around the 20mm or more.

18mm is actually very wide. No it is not anywhere near 10mm, but you can still do those kinds of wide dramatic landscapes quite well at 18mm. I would recommend sticking with the 18-55 for a few month and really exploring your needs before you go jumping into expensive lenses.

This doesn't make any sense. You recommend a 15mm fisheye over a 10-20 type zoom because the 10-20 happens to partially overlap the kit zoom? So what if there is a little overlap? You are still getting a much wider angle of view at the wide end. There is a huge difference between 10mm and 18mm.

You can't directly compare the focal length of a fisheye lens like the Sigma 15mm to a rectilinear lens like the 10-22. 10mm is slightly wider, but not as much as the number might indicate.

Look about halfway down this review for some interesting comparisons of rectilinear projections to fisheye projections.
http://www.the-digital-picture.com …-Fisheye-Lens-Review.aspx (external link)
It appears that the 15mm fisheye projection (not all 15mm fisheyes share the same FOV) has a similar field of view to 12mm on the 10-22.

I think my point about overlapping focal lengths is that ultra wide angle is sort of a one-trick-pony. The difference between the wide angle focal lengths can be important, but you can, practically speaking, "zoom with your feet." When I borrowed a friends 10-22, I found myself always working at the extreme ends. The range in between wasn't that interesting. Either I wanted really wide, or I wanted some more normal projection. for that reason, I don't feel that a lack of zoom in the ultra wide area is a disadvantage like it would be in the normal range of 24mm to...say...100 mm lenses. This taken with the inherent image quality compromises of zoom lenses makes me feel that fixed lenses are a good idea for this range.

I have the Sigma 10-20. It's a very good lens. Not quite the sharpness of some of the other more expensive ones, but it is by no means cheap and is far superior to the kit lens you have now. So if you are happy with your lens now, you will be thrilled with this one.

Here's a neat tool for you to play with.

I didn't compare anything to the fisheye. I compared the vastly different 10mm vs. 18mm rectilinear, since your first post implied that the minor overlap at the long end of something like the 10-20 made that lens a poor choice.

and a fisheye lens isn't?

This makes some sense of your original post, though I still disagree with recommending a specialized fixed focal length fisheye over an ultrawide zoom to a beginner.

Also, the value of having zoom capability at ultrawide or any other focal range depends very much on the photographer. You mentioned the 24-100 range as likely being a better range for having a zoom. Personally, I very rarely use my 24-105. I shoot primes 95% of the time in that range and almost never miss the ability to zoom. On the other hand, when I want wider than 24mm (full frame) I use the Tokina 11-16 on a 7D, and I use it at every point in the (admittedly limited) zoom range.

There are plenty of excellent zooms these days that serve as counterexamples to the "zoom = lower image quality" assumption. e.g. the Tokina 11-16, which is in the same price class as the Sigma fisheye, offers top notch image quality, and is both more versatile and easier to use, especially for a beginner.

While I agree with your general advice to the OP, I disagree that 18mm is "very wide" on a crop body.

Yes, I know I'm arguing semantics, but to me 28-35mm fall into the wide angle range for 35mm photography, not very wide angle, and the 18mm on a crop equals a 29mm lens in equivalent field of view.

Very wide would be 24mm (15mm for crop), with ultra wide being 20mm or below (12mm for crop).

However, unless the OP has experience with very/ultra wide angle photography, your advice is sound. I came to view my 20 and 24mm lenses as two of my favorites in the film days, and I'll eventually buy something in that range again for my T2i, but, as I read the other day, ultra wide angle is not for getting everything in the photograph, but for getting the viewer in the photograph. If used just as a "wider than wide" lens, the photos will just make everything small.

When talking about UWAs on crops, the discussion usually goes to 4 lenses. From what I have read, all of them are very good, they all have good IQ and are all sharp. They all have a fan-base that will tell you that it is the best.

If cost is the critical deciding factor, you picked the right one.

I have the Tokina and am pleased with it. Here are some of the advantages of each, I will not mention 'sharpness' because all of them are. From what I have read:
Sigma 10-20mm f/4-5.6 EX DC HSM: Best price of them.

Sigma 10-20mm f/3.5 EX DC HSM ELD SLD: Fans say this is the sharpest with best IQ.

Canon EF-S 10-22mm f/3.5-4.5 USM: Real USM motor. Fans say this is the sharpest with best IQ.

Tokina 11-16/2.8 AT-X 116 PRO DX: with f/2.8, this is best for low light. It has the best built quality. The downside of this is flair when shooting into the light; it can also be difficult to find.
