Sorry for the delay in my response...I forgot about my original post.

 

I cleaned the contacts on both my lens and body with a pencil eraser (being VERY careful not to get eraser crumbs in the body) and I have never received another error.

 

I highly suggest this before you send your lens back to Canon...it worked like a cham for me (been over a year now with NO problems).

The Li Shuai monolights are the EXACT same monolights as the Fotodiox monolights (even use the same model numbers)...and Shutterbug Magazine wholeheartedly recommended the Fotodiox monolights. Alien Bees ROCK, no doubt about it...but you can score TWO of the Li Shuai L-400A monolights for around the same price as just one AB B400. I think for a beginner / hobbyist I would recommend they pick up a couple of the Li Shuai monolights on eBay. However, if you're a working professional who depends on photography as your livelihood, go with a trusted manufacturer like Alien Bees (if you dont mind using monolights that look like they were purchased from Toys-R-Us...no offense to Mr Buff), or make the investment into high-end gear from Speedotron or Profoto and look like a pro (even if you don't shoot like one).

Perhaps this is what you're looking for...

I found the 3038 to be very solidly built and very sturdy. It's big enough to hold just about any camera or lens you can lift onto it. The locking levers for the ball and the panoramic base are sturdy and efficient. It has adjustable ball tension, so you can set it for the weight of the lens in use. The downsides of this head are the weight and the smoothness of operation. If you have to carry it far in the field, the weight is as issue. If you are working indoors, it's not a problem, but if you compare it to an Arca Swiss B1 - which is just as stable - you're carrying around an extra 3lbs. The ball action isn't particularly smooth. It gets better when you heavily load it, say with a 13 lb lens like a 600/4. You can live with it, it's not aweful, but it's not as smooth as other heads (most of which cost 2x or 3x the price of the 3038). Another potential negative point is that it uses the large Bogen hex QR plates. They work fine, but are significantly larger than, say the Arca Swiss QR plates. Still, if you need a BIG, stable ball head, you don't have much money and you can live with the hex QR plates and a slightly sticky ball movement at times, the 3038 is a reasonable choice.

I just received my first (and only, so far) "ERROR-01" message on my 20D/BGE-2 with my (brand new) EF 70-200 2.8-IS. I was shooting a hockey game, so I thought it had something to do with the cooler temp inside the rink. I removed the lens and used my Q-ball to blow out any dust that may have accumilated, then re-attached the lens...after that everything was fine. I didn't know it was an image stabilization problem with this particular lens until I researched "ERROR-1" on the web. I have two other IS lenses (the 17-55 and the 10-22), and neither one have given me ANY trouble...however, they are both EF-S models, so I dont know if that makes a difference or not.

 

I had taken about 350 consecutive shots in RAW mode (in 3 to 5-shot bursts) within a 15-minute time frame, so I don't know if that contributed to the error...but this is only my SECOND shoot with the lens, so I'm extremely concerned that I may have a bad copy. After reading the multiple reports about ERROR-1 messages associated with the 70-200 2.8-IS, I decided to file an official report with Canon while the lens is still under warranty. The tech support rep suggested that, even though the lens is new, I clean the contacts on both the lens and body just to make sure there isn't any oily debris on either.

 

I will post any further developments.
