You spent $650 on a Sigma? And a 10x zoom at that. There has to be a good bit of distortion and vignetting with that lens. I would not trust any zoom that has more than a 3x difference between widest and longest focal length on an SLR. If I'm spending $650, it's going to be on a Zeiss prime, not on a 3rd party zoom.Originally posted by: fuzzybabybunny
As for $300 a pop, I got my Canon 50mm f/1.8 MKII for $35, my Sigma 30mm f/1.4 for $300, and my Sigma 10-20mm for $400. The only lens over $500 in my repertoire is my Sigma 50-500mm, which I got for $650.
Used lenses are where it's AT! FredMiranda's Buy/Sell baby!

The Sigma 50-500 (or lovingly referred to as the "Bigma") is a very good lens.
Here's a couple shots from one by a guy I know:
http://www.buzzdns.com/lion1.jpg
http://www.buzzdns.com/lion2.jpg
The second shot is a 100% crop. This was a HANDHELD shot.
It's excellent for wildlife, sporting events or airshows. It has an excellent range.
So $650 for that lens I would say is a good deal.
Here's another image:

So no, it might not be as sharp or as fast as a Canon prime or something, but it is in NO WAY a bad lens.
And speaking of Canon, $650 wouldn't be enough to buy the best prime they have. Try $2000.
And if you want a 500mm Prime....that'll be about $5500 TYVM.

And yes, $650 won't buy the best prime on the market. It'll buy a decent Zeiss (the special order models can run upwards of $10K), but it won't buy the best.
The point is not that the zoom is junk, just that a prime will always be better. And a Zeiss will be better than a Sigma.
Also, you give me only re-sized images from a digital (how much post-photo editing was done?) and a 100% crop from the center of the frame (the place where even sh*t lenses are good) and you don't give any specs on the images (shutter speed? film speed? aperture?). If the lens wasn't wide open, you really can't use the shot to compare lenses since every lens is decent by F8, and most are decent by F5.6, so if it's been stopped down, the image doesn't tell us anything. Also, what focal length was the zoom at? Most zooms are decent in the middle of the range, but show distortion at wide angle and vignetting at telephoto, if the picture was taken at the mid-point of the zoom range, it again doesn't tell us anything at all.
Photodo's MTF specs for Sigma lenses are nothing special. There are a handful of good performers, but a whole lot of mediocre preformers. (I'll grant that they are better than Tokina or most Tamrons though.)
For my money, I'd rather buy the prime. It'll be faster and sharper than a zoom at the equivalent price point. If the Sigma 50-500 is sharper, faster, and cheaper than Sigma's 500mm prime, then something is seriously wrong with Sigma's ability to fabricate a prime lens.

Will, say, a $650 50mm Zeiss prime be sharper than a 50-500mm Bigma? No... perhaps at 50mm and a bit beyond, but anything 100m and above you'd have to crop the Zeiss prime's pictures like crazy just to get the FOV of the Bigma. The argument is completely moot because it's not even the same focal range. There's no point comparing a 10x zoom to a single prime that's not even close to encompassing the range of a the zoom.
And yes, $650 won't buy the best prime on the market. It'll buy a decent Zeiss (the special order models can run upwards of $10K), but it won't buy the best.
The point is not that the zoom is junk, just that a prime will always be better. And a Zeiss will be better than a Sigma.
Zooms are getting pretty close to primes in IQ. Zeiss will always be better than Sigma, but the price gap alone makes the comparison unequal... not to mention you have to have a camera that'll resolve all that detail in the first place, another $6000+ investment for Canon's top of the line or the price of a luxury sedan for a medium format back.
For my money, I'd rather buy the prime. It'll be faster and sharper than a zoom at the equivalent price point. If the Sigma 50-500 is sharper, faster, and cheaper than Sigma's 500mm prime, then something is seriously wrong with Sigma's ability to fabricate a prime lens.
It's not... and what if you have a 500mm prime and needed to use 200mm, 300mm, 400mm, etc? Again apples to oranges.
ZV
EDIT: And yes, in the 400mm+ range a Zeiss can set you back almost as much as a small used car.
I guess I just don't like zooms unless I'm just playing. I love my Zeiss 28-70 for a walk-around lens, but for real work I want my primes. I'm a weirdo though, since I do not like autofocus and won't use it, which limits my choices. The autofocus lenses I've tried have sucky feel when manually focusing, no dampening at all.
I'm actually extremely partial to primes also. The most used lenses are my 50mm, 30mm, and 180mm primes. I love their sharpness, weight, and brightness. And since I use my 50-500mm at 500mm about 80% of the time, I would really like a 500mm or 600mm prime. But I don't have even close to enough money, so the whole argument is pointless.
Not to mention all I've got is a Rebel XT, and I see absolutely no point in slapping an excellent lens on an inferior body. In my case getting a Zeiss would be akin to just throwing my money away...

Which lens did you have in mind? I was thinking of the 200 1.8, which goes for $3600-$4000+, depending on condition. Of course, you can't buy it new anymore, so they're always used prices. 😛

The 85mm F/1.2L Mk II - Arguably the best glass Canon makes when it comes to image quality.

I know that I have heard of problems with the AF in the 75-300 lens when in portrait orientation, but I'm not sure if it's in this one or the IS version, so you might want to research that.

Keep saving then for a better lens. You'll only end up rebuying what you really want later down the road. I know from first hand experience.

Compare any DSLR today to any DSLR from 5 years ago. They sure didn't improve much, did they? :roll: There's always room for improvement, features, and abilities in anything.

Grab the Canon 70-200mm F/4L It's only about $500 (maybe a bit more) and is an awesome piece of glass. It's not 300mm, but on a 1.6X crop body you get a 320mm FOV. That might work for you.

Um, compare a film SLR to a film SLR from 10 years ago.
How much of an improvement in the camera (not the lens) do you see? Being that we have seen little improvement in the last ten years and that DSLR bodys are just as good as film SLRs now, we are not going to see much improvements in the future.
Tell me how exactly full frame helps other than with wide angle shots?
The are cameras with room for 40 frames, they are called video camera.

You kind of have a point, but you miss that a $650 500mm prime will perform better than a $650 50-500mm zoom. Why not just spend $650 on the 500mm prime and have a faster, sharper lens? How can a company make a 50-500 zoom for $650 and not have a 500mm prime in the same price area? It just doesn't make sense.Originally posted by: tfinch2
While what your saying is all nice and well, you have to look at the cost-benefit of equipment for the amatuer/semi-pro. It's hard to justify big money for a high quality speciality prime that you'll use seldomly unless your a pro.

I've got a Sigma 70-300 APO that I shoot with every now and then, but I am partial to the 135 F/2 L. 🙂 Definitely my favorite piece of glass that I use.
$199
It's not the fastest or the greatest, but I get a lot of decent shots. Range and IQ are good for the price.

Is this the same thing? I can get it for like $120 pricematched and couponed.

Looking at Sigma's site, it appears that they do though. Given that it seems to be the cheapest way to get a 500mm lens from a known manufacturer I'm going to have to retract my previous statements regarding buying it. Yes it's slow at 500mm, but it seems a decent way to get into that length.
Thank Heaven that I shoot landscapes. I almost never need more than a 50mm lens (though I love my wides and macros). One of these days I'll pick up a 100mm and a 300mm prime and I'll have all the telephoto I'll ever need. Possibly substitute a 135mm for the 100 for portraiture.

OdiN, I had a hunch you were going to say the 85 1.2! You can get them used for a dang good price (usually sub-$1500). It's quite the lens, but the AF is too slow for sports, which is what I like to shoot the most. Yeah, different people use different glass, I respect that! Nice choice, nonetheless! An online friend of mine uses it a lot and the bokeh is just AMAZING.
