My Own Lens Question - DPChallenge Forums

Does it matter if it specifies that it's a wide-angle lens? It seems like most of the lenses in my price range say they are also wide angle. Personally, I'd prefer a straight forward zoom, but....

It's my understanding that it depends on the 'focal length' and what your shooting and what you want to achieve.

Hope this helps explain it better then I could.

You also have to take into consideration the 1.6x crop factor. 50mm isn't 50mm on a 30D.

Alas, my price limit is going to be about $300.

This is the lens I'm thinking about right now:

For a couple dollars more be sure to check this one out:

Slow at the long end, and not the best lens around, but some people have taken some amazing photos with it.

edit to you add:
as to your original question, wide is just a term to describe a lens. I think any focal range below 35mm is considered wide and any over 100mm is telephoto or something like that.

Above example of 35mm is based on the camera's multiplier factor e.g. Canon EOS 20D has 1.6 multiplier, which means if you have lens say 18mm to 200mm that eventually would be 18*1.6 = 28.8 now this is considered to be wide lens but if you have 28-90 then it would be 28*1.6 = 44.8mm now this might not be wide for Canon EOS 20D.

My bad, I didn't check the price, I thought it was cheaper. You can get a used one on amazon for $289 though.

Yeah, I'm considering that one. The seller has a good rating.

Not that they are BAD lenses, but I would avoid the Sigma DC lenses. They quality of shots you get by getting an EX is MUCH better and you would be happier in the long run. I'd suggest the Tamron 28-75 f/2.8 for starters and then get 1 wider and 1 longer lens as your budget allows.

Added: Here is a complete list of Sigma lenses. The prices are MSRP and can usually be bought for less at B&H Photo or Sigma4Less.

How's this one? //offer.ebay.com/ws/eBayISAPI.dll

And when you're looking at lenses how do you know if it's crap or not? I mean besides by the price.

That link isn't working. Price doesn't always dictate whether it's crap or not. There's lenses that people wouldn't buy because there's a better (or same quality) lens they can get cheaper. Check reviews, ask someone who has a lens your interested in, etc.

P.S. That link doesn't work. If it's an EBay item, copy/paste the auction number.

1. Read the forums/reviews (dpreview, fredmiranda etc) keeping in mind that people tend to exaggerate both the bad and the good. If very few are saying anything good about the lens, avoid it. If the opinions are mostly good; buy it.

2. If it's a zoom, anything over a 3-4X zoom ratio is gonna be a compromise.

3. Go to a store and try it out if possible.

The listing doesn't have very much detail about which lens it is. What's the f ratio? What's the model? When was it purchased? What do the elemnets look like? Are they scratched?

If you are serious, ask the seller some questions. From what I can see, there's not enough info to make a good decision, so I'd stay away until I got more info.

This is the only review I can find for this lens, but it seems like it just might be a decent lens:

Don't bother with that lens. It's very slow, especially at the long end where you need it most. The 28-75mm 2.8 (constant) is a great lens, and it's a little under $400.

That 24-70 might be OK optically, but I wouldn't count on it. The 28-75 is at least as sharp as the 50 1.8 prime at similar apertures. The 50 does *seem* to give me better results color-wise on Fuji film than the 28-75, but there's so many variables involved that I can't really make that statement outright.
