I'm waiting to see what the MTF charts look like, compared with the old ones.  The DR too...how many stops?  It could be a while though, with Canon's track record lately, they'll be $40-50 each and available "late 2013."  Twice that for the ones with a red ring.

</sarcasm>

On a more serious note, has anyone actually done a study on using "dark frames" to calibrate sensor noise?  Shoot a few frames with the lens-cap on (same exposure) and then shoot the subject... then "average" the dark frames and "subtract" them from the "real" shot in post, as in Astrophotography?

One wonders whether it may be possible to do the same "in-camera" by doing a pre-read of the sensor before the shutter actually opens...

I'm still trying to wrap my head around why someone would argue against using lens caps...
Every lens i've sold has been mint, not because i didn't use the daylights out of it but because I lens capped them and always used a hood, and I don't keep filters on my lenses for protection.

I think it was just that one professional not 19 yr old dude that hasn't used a lens cap since 2005! Everyone else agrees that they are quite important!

I wonder, are they weather resistant ?  ;D

Dang u beat me to that point, weather sealed like the cpe-4 and the 580 exII and 600 flashes among others have all gotten the seal to protect against bad wether. Honestly keeping moisture out due to having some kind of sealing property may be useful. I like the idea of both caps having a seal as well as the cap that goes on a camera body, why the heck not!?

By the way, the lens caps look like they will be $10. I just looked at accessories for the 35F2 and it shows lens cap E-67 II $10

This will make it much easier to put the cap on a lens with a hood attached.

I feel like I'm the only person who has never had a problem with the Canon lens caps. Even when putting them on something like a 70-200 F/2.8 with the hood mounted, I've never had a problem doing so.
I have a tamron lens, and I do use the pinch feature of the lens cap  but that sometimes results in the cap slipping out of my fingers and hitting the front element...

Hmm, I guess I'm just weird.

After 1Dx and 5D3 they seem to try to make us wait for a really useful product. After the introduction of 24-70 f/4L IS and 35 f/2 IS at such high prices, the new caps seem to be the culmination of their effort!

I have not had a problem either... So I guess we're both weird :)
