Trying to make sense out of Canon lineup decisions is maddening.  For instance, why start putting IS in your wide angles rather than your telephotos???

Why is there so much fuss about the quality of a $1000 lens that comes with a 5-year guarantee?

Cuz it's too damn cold and crappy outside to do anything else  :D

I'm thinking (hoping?) this lens will pleasantly surprise.

It will

Now that's just teasing !!!!
Looking forward to your review, do you know when/where it will be published first?

Yes Dustin, it's not nice to tease the less fortunate. :(

As to why all  the fuss.  It looks like this lens may be better optically than a canon 100-400mmL and is about 2/3 the price.  There hasn't been any real competition to the canon 100-400mm for way too long.   If enough of the established testers give this a thumbs up I'll be getting one, tired of wating  for an update of the 100-400.

Sigma should also be worried as none of their  400mm or 500mm zooms beat the 100-400mmL.  Although Sigma could be eating canon's lunch with their 35mm and 50mm primes.

Now, I would say it's a good idea to wait until several reviewers have weighed in and frankly, I would want to wait until someone like Roger Cicala has a chance to run several dozen or several hundred copies through his system so they are thoroughly field-tested and any problems can be identified before buying. But I don't like blanket statements without any evidence to back them up.

Unfortunately Roger can't test the lens at 600mm which is where most people want to know how good it is.


EOS Bodies / Re: EOS 5D Mark III & Third Party Batteries

I've got two batteries  that worked fine before the firmware upgrade, they still work fine but you have to OK them.  I also have two wasabi's that I purchased several months after the "upgrade" and they register normally.
Canon's playing a losing game.  The third party vendors adjusted quickly to  Canon's change.

The total cost of the four third party batteries was less than the cost for one genuine Canon.     

The smaller size of the 500 II would make it easier to travel with, especially by air.  As you say, the most significant differences are the cost and the 100mm of focal length.  I'd say the 500mm would be better for wildlife and birds, whereas the 600mm is better for birds and wildlife.  Since the latter more closely matches my interest, I went with the 600 II.

I had an elementary school teacher  who when teaching set theory tried to tell me that 3 x7=21  was not the same as 7 x 3 = 21, some how the order of the number of sets  and number in the sets  was important to determining that there were 21 total  items. :)

Both are great lenses.   Personally I went with 500mm for the lighter weight, even though my interest is birds and wildlife.

I would keep it.
For some activities being able to zoom is critical.
I use a 150-500mm Sigma for airshows not my 500 prime.  As the plane passes along the flight line you need to adjust the focal length to keep all of it in frame.

Scroll down to the bottom of the link and you will find the price of the lens in US dollars ofver the past couple of years.  You will also see that the lens is frequently on rebate.

I prefer the 100-400 IS L replacement instead of the 200-400 Extender, because it´s really a pain to travel with the 200-400 Extender. It´s to heavy.

The weight of the lens is balanced by the lightness of the wallet. ::)

Lenses / Re: Things to get when you purchase a 600mm?

LensCoat:  I used it without one for 8months but since I was always walking through bush, I decided to get it and protect from scratches.

If you get LensCoat then the included lens cap with the 600II doesn't fit very well so either a LensCoat Hoodie XXXX or a Don Zeck cap is in order.  Without LensCoat the new markII caps work great and no need for an aftermarket one.

Replacement foot, I use RRS one now but have the 4th Gen convertible CRX-5 low mount one on the way (intended to use with my new 300II but I'm going to try it on the 600II also).

+1 For a lenscoat for scratch protection. You can get plain ones, they don't have to be camoflage. I cut the       transparent plastic off to give me access to the controls
+1 For the LensCoat Hoodies for when you have a lenscoat on 
+1 For the CRX-5, I'm using it on a 500mm

I'm happy to confirm that I will have my hands on a pre-production copy sometime over the next month or so.  I'll let you know everything that I'm allowed to share during my review process.

good to know

What I expect to see and would be less willing to buy...

EF 35mm f1.4 II L
EF 50mm f1.8 IS
EF 85mm f2.0 IS
EF 135mm f2.0 IS > with the 200mm quietly dropped
EF 300mm f4.0 IS L
EF 400mm f5.6 IS L
45mm & 90mm tilt shifts replaced

Wild cards ?

How about a 600mm or 800mm with built in 1.4x extender or a 50mm f1.0/0.95 or an autofocus lensbaby style lens ?

Dream on ;-)

I think you will see a 100-400mm replacement before a 400mm f5.6.  Canon sells about 10x as many of zoom compared to the prime.

I shall get the new 100-400 the day it becomes available.  8)

I'll wait six months till the price drops.

Having used a 600F4 (not mine... wish it was...) the difference between the latest long lenses and the old designs is night and day... it really spoils you... The 400F5.6 is not a sharp lens. Modern zoom lenses like the 70-200F4 are significantly sharper and even with a teleconverter can out-resolve the 400F5.6 , and when a zoom lens is sharper than a prime, you know the prime needs to be re-worked.

Not sure this is going to happen.  Look at  the 200mm F2.8L.  The 70-200mm zooms have gone through two or more iterations and are now arguably sharper.   The 200mm f2.8L is about the same vintage as the 400mm f5.6L, both were stellar lenses in their day, but the trend now is for zooms.  Just be glad canon has kept producing the 400mm. No one else has anything comparable.

Sigma 10-20mm f4.5-5.6 HSM. 
I started with a T1i and the 18-55mm 55-250mm and 50mm f1.8.
The Sigma was my next lens purchase and the focussing speed compared to the other lenses  impressed the hell out of me. 
My next lens was the 200mm F2.8 L and again the focusing speed  was incredible.  A long list of USM, HSM, USD lenses have followed.
