So now that I am narrowing down my lens choices, what is the difference in Canon's 'L' and other series of lenses? I know that 'USM' means ultrasonic motor for a quieter autofocus. It may be a mute point, because I really want a fast 50mm lens. I plan on adding the following lenses to my arsenal:

    [*]16-35mm f/2.8L USM Ultra Wide Angle[*]50mm f/1.8 II Standard Autofocus[*]Sigma 135-400 f/4.5-5.6 APO Aspherical Autofocus Telephoto[/list]
    I'd like to be able to buy a really fast 400mm lens, but I just can't justify almost $3,000 for a lens I will use less than 5% of the time (unless the Jaguars hire me to shoot some at their games). I plan to use the 400mm Sigma to capture the first kiss when the pastor won't let me close to the action.

    Anyway, could someone please tell me what the different series of Canon lenses are all about?

    Thanks, Mike

Quite simply "L" lenses are better. They are built from the ground up with the professional in mind. In terms of optical quality and construction Canon's L lenses are the best you can buy for a Canon camera at that focal length. They're sharper, faster, more rugged, and have higher quaily glass in them, and have more engineering behind them.

Having said all that a 400L lens might not be right for you. If you can't justify the expense, don't buy it. If it's worth it, you'd know it. You'd be able to say, "in X number of jobs the lens will have paid for itself." I'm not saying you can't splurge on a passion, but if this is a business descision, you have to treat it like one.

Also remember that the photographer has more to do with the image than the lens. The lens just forms the image, you descide what's in it.

"L" lenses contain one or more of the following lens elements:

    [*]Ground aspherical element[*]Ultra-low dispersion (UD) element[*]Super Ultra-low dispersion (Super-UD) element[*]Fluorite element[/list]
    These elements are primarily used in telephoto lenses, wide-angle lenses (which on SLRs are reversed telephoto lenses), and "faster" (larger aperture) lenses.

    Note that of the TS-E (tilt-shift) lenses, only the 24/3.5 is an L-series lens, even though they are built to pro standards and are priced accordingly.

    Most of the standard prime lenses aren't L since these elements aren't really needed.

    Note that the Canon 50/1.0 isn't sharper than the 50/1.4. You're paying for the additional stop.

    Additional information on Canon lenses can be found at Photonotes.org.

    On the brighter side, at least we're not dealing with the alphabet soup for Nikon lenses. [img]/ubbthreads/images/graemlins/tongue.gif[/img] That AF-S 70-200/2.8 ED VR G lens is a mouthful.

What's wrong with a 100-400 USM IS lens from Canon? It has IS for your hand held shots in the church that you are talking about..

Also, you can buy a used 400mm f2.8 lens for about 3500 in good shape...and even if the cosmetics are ugly, the images you can get from a 400mm f2.8 are remarkable! ...and better than any Sigma lens.....especially a zoom..

I'd just skip the 50mm f1.8 and buy the much better 50mm f1.4....trust me, it is much better..

The difference....several things.. Sigma doesn't like to repair their lenses...even if it's under warranty.. My friend Dan can vouch for that.. it took him 6 months to get his crappy sigma lens rechipped to work with his 10D..and 1D bodies.. Contrast and resolving power is no match...Canon is just better.

If you will be doing general retail and commercial stuff, the 400 mm range will gather dust on your shelf. It's big and heavy; think about what you would use it for. In environmental portaiture, I think a fast 300 would be more useful.

Second, consider a fixed 85 mm lens. For years a Canon 85mm f1.8 rarely came off of my F-1. If I shot 35mm, that was more than likely the lens I used, rather than a 50 mm.

Also give some thought to a 100mm macro lens. I used mine quite a bit; really good for getting tight facial portrait shots.

Before buying lenses, check KEH prices http://www.keh.com. Their BGN level lenses and bodies (mrk on the body, but perfet internally) just about completely quiped my studio.

Hi Mike,
For the money, you cannot go wrong with the 50 1.8. Under $100 and fast!! I too agree with JP on the 100-400 Canon lens. Same F stop and Canon speed and quality. I have dealt with a great dealer and he sells the 100-400 IS Canon for $1349. When tax time comes around, I will be adding that one to the bag.
I recently purchased a 17-40L from them and I am just amazed at the photos with it. Plus it is much cheaper than the 16-35. I picked it up for $669. If you want contact info, just email me.

Don't know what you had as a total on the lenses listed but I come up with right around 2100 plus shipping. I ran BH prices and it is almost a wash. I know you probably would be much happier with a better telephoto in the long run with IS, and lose a stop and mm on the wide angle. That IS will gain you a stop of two most times.

Plus of course being able to say you own 2 "L" lenses is a macho man thing, and all the girls just love big white lenses. [img]/ubbthreads/images/graemlins/wink.gif[/img]

I notice that the only camera identified in Mike's portfolio is a 10D. That's a 1.6x crop factor camera. When you multiply 50mm by 1.6 you get... 80mm equivalent. That puts Canon's 50mm primes, especially that sweetheart-deal f1.8, within spitting distance of the 85mm portrait standard.

Jason sold me a Canon 50mm f1.8 for a great price and it's my go-to lens for any number of situations, including some very nice night street photography. I recommend it highly. I mean, sure I'd love to have an even faster L lens, but I still would want a 50mm.

50mm = 80mm on a 1.6 FOV......well, sort of..

The thing to remember is that regardless of the format, the distance between the film / sensor plane and the front lens element determins how much depth of field you will have...and a 50mm lens won't have the same shallow depth of field as an 80mm lens.. Try it sometime side by side with a film body and a digital body and focus at a target ten feet away..

I just like to use my 85mm when ever I can..when I'm inside... With a film body, I like to shoot with the standard lens for full length shots..with digital, I use a 35mm prime lens for full length shots...because I have to...not because I'd prefer that....because I really don't..

Like Nikon's ED stuff. I also think they are constructed to more robust standards as well (more metal and less plastic) to stand up to the rigors of professional use.

 
 
Just don\'t be like this guy... ;-)

I was covering some football the other week..and this guy who was shooting with a film body brought out his 70-200mm f2.8 IS lens and was shooting it from on top of his mono-pod the whole game..

The funny thing is that I was covering the same game, and I had my 70-200 on one shoulder...and my 300mm f2.8 with a 1.4 x teleconverter on my digital cameras...and shot hand held with both.. I can't stand using mono pods unless I am shooting with very heavy lenses like the 400mm f2.8 which is a 17 lbs combo when paired up with a 1n with the power booster....which is actually heavier than the 600mm f4 lens..

I just about LMAO at the site of this guy...and so I just had to say hello to him.. [img]/ubbthreads/images/graemlins/smirk.gif[/img]
