100-400 mk2 vs sigma 150-600

[paulbrogden10]

Hi all been thinking about the sigmas 150-600 both s and c vs 100-400 mk2 any comments the sigmas are cheaper and have much longer reach.

sigma c 150-600 £750

sigma s  150-600 £1200

Canon 100-400 mk2 £1400-1700

The sigma c seems a bargin dont it?

"...a single unassisted camera battery to supply enough current to drive a large lens's autofocus motor at its rated speed."

It apparently doesn't effect a 1 series as I have never noticed it. I have owned all of these (and more) large teles, they seem to perform like any other big lens.  Of course the bigger the lens the bigger the mass the motor has to move so it will never act like a 70-200 for instance.

Don't your 1 series cameras take two batteries? I thought the 1's had all the capabilities of a battery grip built in.

It's a single double capacity battery. It's the Double Mint of batteries.

Actually like 10 Mints (cells) in one.                                                    Photo by Kang Liat Keng

"Don't lose focus, Guys. Battery life isn't the issue, is it? It's the ability (or not) of a single unassisted camera battery to supply enough current to drive a large lens's autofocus motor at its rated speed."

I do believe that the OP said that he does use a battery grip.  I do not know Paul experiences slow performance right out the gate, or not.  I think he has said in past posts that he has changed to new batteries.

There is something unique, and out of the ordinary, about his experiences with large lenses.  I have found that the 100-400 mk2 focuses very quickly, provided I use it effectively.  Using the wrong AF mode can give you sluggish AF performance.  I don't know if it is my imagination, but the lens does seem to acquire a target and lock focus faster in One Shot mode, compared to AI Servo.

Actually, the 100-400 mk2 is arguably identical in size and weight as the 70-200 mk2.  Close enough that they both come with the same storage bag from Canon.  In other words, if his camera has not had trouble with the 70-200 mk2, then it shouldn't have any trouble with the 100-400 mk2.

In fact, the 70-200mm has 23 lens elements in 19 groups, while the 100-400 has 21 elements in 16 groups.  I would expect that the 100-400 has slightly heavier lens elements than what are used in the 70-200, but the difference would seem to be insignificant.

Good lord, you guys really need to stop detailing a post to the last degree.  Let me explain, again, to you.  This statement was not intended to compare the 100-400 to the ef 70-200mm f2.8L ounce for ounce.  It is a general statement describing the advantage lighter lens will have over larger ones. That's all.  

Glossed over this, "I have owned all of these (and more) large teles, they seem to perform like any other big lens.", didn't you?

B from B,

"Don't your 1 series cameras take two batteries? I thought the 1's had all the capabilities of a battery grip built in."

A 1 series does not have a grip and none is available for it.  The extended area where a grip might be has some electronics in it, like an LCD screen and some buttons.  That area is occupied only about half way with a proprietary lithium battery.

BTW that photo shown elsewhere here is from and older Mk II.  It is a ni-cad, circa 2005.

Uh, the "bigger lens" in question, which Paul has been experiencing battery issues with, is the 100-400 mk2.  Nice try.

"...  the "bigger lens" in question, which Paul has been experiencing battery issues with, is the 100-400 mk2."

But it wasn't my intention.  Nice try!  You may want to point that out to Paul if you feel it that important.  Just perhaps Paul might have or buy, in the future, another or different lens besides the 100-400.

It is never your intention, but it just usually seems to work out that way, your needing to clarify and clean up what you post.
