Youngnuo MC-C3:Intervalometer = AWESOME! Me = Not so much...

You could spend $200 + on the official Canon Intervalometer,but if you're like me, you are a poor 

starving artist and every dollar counts so my advice is put that $200 under your mattress. You can

buy a 50mm 1.4 for $300 and that lens has become a steadfast workhorse for me. I bought my 

intervalometer for $34 on ebay http://cgi.ebay.com/TC-80N3-timer-remote-for-canon-50D-40D-30D-20D-1D-etc_W0QQitemZ370215596773QQcmdZViewItemQQptZCamera_Camcorder_Remotes?hash=item563291b2e5#ht_2264wt_941 
This seller has a great rating and for good reason. Delivery was prompt and the item 

works like a charm. However,if he has sold out, the link to the item on the manufacturer's site is here.

I found it to be very simple to figure out and shot my first timelapse ten minutes after it arrived 

(plus the half hour it took to shoot). That being said a few friendly words of advice I learned the hard 

way.

1) Don't set the Canon 7D on Auto ( at least indoors). I made that mistake and the flash would fire on 

some shots and not others creating a very undesirable flickering effect when I played the timelapse 

back.

2) If your using a 50mm 1.4 and doing a timelapse of making eggplant parmesan. Don't put the garlic 

container or spoons to close to the camera as this also causes a very undesirable focus shifting effect.

3) Once you are done shooting and have transferred all the stills onto your computer. Do not. I repeat

DO NOT select all 5,000 + stills and then click - Open with Quick Time.Although this will provide

some entertainment as 1000's of huge QT windows pop up on your screen, this will quickly turn to 

aggravation as your computer slowly grinds to a halt and crashes. Luckily no damage was done but I 

definitely got a bit of a scare doing this. Instead I would advise selecting the first Image in the

folder and then in QT selecting Open Image Sequence or something to that effect.

-So what I have learned is that despite the natural learning process of trial and error the Youngnuo 

intervalometer works great. Hope this is of some help!
