EF 24-70 f/4L IS & EF 35 f/2 IS

[TWI by Dustin Abbott]

The 100L macro was well over a thousand when it came out.  I got a deal when I got mine and it was still slightly over a thousand...a year after it came out.  The only "L" zoom that has a lower MSRP than the new 35 f/2 is the 17-40L.

BTW, comparing initial MSRP to the used/discounted prices of older lenses is a fallacious argument.  You need to compare with their initial MSRP

This was exactly the point I was trying to make in my previous post.

Furthermore, Canon is including a lens hood and bag with this new lens (35 f/2), which indicates to me that this lens is a cut above the typical non L prime.

It's now been pretty much confirmed (by two separate sources from Canon USA) that this is NOT true - the 35mm f/2 IS will ship without hood and pouch, just like nearly every other non-L lens. 

Note that in other geographies (some Asian countries), all lenses ship with a hood, even lenses like the EF-S 55-250mm and the 40mm pancake.  But not here in the USA.

That is the first that I have heard this (regarding hood and bag).  I'm surprised we haven't heard any hands on previews/reviews at this point.

Since My L bags all sit inside my largest L bag in a box, it's a non issue. Hoods are a different matter.

+1 on that.  The bags are useless; hoods are not.  That being said, I have gotten by with several $5 Ebay special hoods before and it has never been an issue.

Question - when you need fast SS to freeze action is it better to switch IS off? Does it get in the way? I usually just leave my IS on all the time, should i switch it off if my SS is 1/focal length, crop factor adjusted?

Say you were to shoot a landscape at 1/200s at 24mm (obviously don't need IS) but is is there any reason why I should switch it off? Assume I have no tripod.

At what point does IS have a noticeable effect? Like what is the threshold?

Good questions - I asked the same one some time ago and no one came up with a conclusive answer. My 2 cents for handheld (for tripod turn IS off and mlu on esp. for longer exposure times):

At very high shutter speeds turn IS off because the vibration might decrease iq (also see here: http://www.canonrumors.com/forum/index.php?topic=10781.0). For other higher shutter speeds turn it off unless you require the stabilized viewfinder to track an object or set the af point just where you want it. Another reason for turning off IS when it's not really required is simply that it doesn't wear down that way - Canon doesn't give us a 6 year warranty like Tamron :-o

Personally I think IS is unnecessary @ 1-2 stops faster than 1/(focal lenght * crop factor).

hello,

I turn IS off when I use tripod. You see once I used my 70-200 f/4 L IS in a very steady tripod, mirror lock, 2 sec delay. The speed was 30sec. I got an extremely blurry picture!!! I begun to getting confused, angry, etc when it downed on me to turn IS off. Bingo. Pictures were very sharp afterwards! Then I read at the lens' instructions that IS has to be off when the camera is in B mode. Well it was in Av mode but as the speed was 30sec I guess the instruction was close enough.

By the way, thanks for the reference to high speed SS in conjunction with IS. I remembered I had read it in the past but to tell the truth I had forgotten...
