Would explain mine too.
easy enough to avoid though....
if you think you need it, try it, if you see an noticible improvement, great, if not turn it off, and grab your tripod.

that could be an issue with my observations.

in low light I switch af and exposure to manual, and I'm usually faster than the camera could be on auto, so I would never have bothered to wait for any kind of sr lag if that's what you might call it...

what they don't show is a charactoristic of rolling shutter design that causes vertical lines to slant (imagine a tall building waving side to side like a blade of grass in the wind) when you move the camera (panning) quickly....
but yes those types of shots, I'd love to have to mix in with my videos for wedding customers...

here's a link to an article link

That is what I thought, but it does get a little confusing, when companies revive a good name to sell bargian basement stuff......

I think only limited lens/camera/flash combos in the canon line work well together. you need a newwer EOS body and EX flash, COMBINED with newer lenses to get it all to work.

The main reason I dislike canon, is the way the company comes out with a new feature every few years, then they try to force you to buy a whole new system........even the way they try to force out other brands... at a time when most wedding photographers were toting vivitar 285's and 283's, canon decides thier "New" af bodies, had to have a new lensmount, new flash units, AND a rediculously low voltage synch, to make damn sure you couldn't use your existing vivitar flashes. Once you bought all the new kit, they introduce in lens image stabilazation, forcing you to buy new lenses, if you want that feature....then they upgraded the flash system, to work with new lenses, and new bodies again.
Much worse than Pentax. (pentax made the first slr with af, i believe; the entire focus system including battery was built into the lens...somebody who knows more than me can fill you in if that me-f body and 35-70 lens had any comatibility with other pentax gear)

I have never shot a wedding yet, where some photoenthusiast/pro/wannabe pro didn't start yapping about gear, and walk away astounded at how well I my gear spanning twenty-odd years works with the latest gear.
When I bought my first( second hand) camera, I started out with Pentax gear that was older than me. I still use the same m 50mm 1.4 i had then, and also the af 50mm 1.4 I bought last year. And my vivitar 283's side by side with my 500 ftz, and 360 fgz.

really? what do you guys figure an old tak-a 70-200 would be worth?

have you guys seen the new lensbabie? it's got a hollow ball and socket joint in the center!

Well a ringflash is not for you, that's for sure.
I photograph alot of women. and when it comes to older women, filling in those lines on the skin is a plus, getting nice 3d modeling off the texture of the skin is not so desirable.

for fill flash in the sun, it's like having a big old softbox, in a portable container.....
like the mirror lens donuts, the ringflash shadow is an aquired taste, I guess.

Let's all bow our heads and pray to the lens.
