Away from you is pushing. Towards you is pulling. That makes no sense.
Depends on which end of the lens you’re looking through!

Well, I hold my camera with the front of my zoom pointing to the object and move the zoom ring forward away from the camera body, this action that I call it "pull". This action will put my two zoom lenses on the wider side of the zoom range. On the other hand when I move the zoom ring backward to the camera body, this I call it push, this will put my two zoom lenses to the longer side of the zoom range. I don't look at the front of the lens to zoom. By the way I have an other push/pull zoom lens acting the opposite way! So it doesn't matter if the lens is either push/pull to archive the zooming!

My Bad, should have said Sigma/Tamron was not sharp.
Canon, series II much better than series I.

Not sharp? Totally disagree. What are you basing your "opinion" on?

Not always! My Nikon 35-70mm f2.8 AF-D and the Vivitar 70-210mm F3.5 ser.-1 work the other way, pulling out to zoom out, pushing in to zoom in.

Very bizarre and counter-intuitive. I had to look up the Nikon and just ordered one used from Adorama.

I have had both and prefer twist over push/pull. The push/pulls have a tendency to "loosen up" over time. Some, over time, will had a tendency to "zoom" or creep when the lens is hanging down. Sometimes this can work against you. It will usually start you at the telephoto end and in a less compact state than when it is at the wide angle end.
Understood, but just to add, the 100-400L version 1 has an adjustable lock to prevent “lens creep”

A push pull photographer at a game looks more like a fellow who knows what he's doing.

I didn't know that, guess I’ll keep my version 1

I'm looking at a few lens, and wanted to know if there was any pro's or con's to the two systems. Some of the lens are push/pull type for zoom and some other are "twist" to zoom. I was told that push/pull will force dust into the lens but the "twist" lens the barrell extends and retracts when you twist. amy input is greatly appreciated. Some of the len's I'm looking at:
Sigma / Tamron 100/400 150/600
Canon 100/400 Ver 1 and 2

Hi Tom I own the Canon version 1 100/400 now for at least 10 years. Can't tell you how many miles I walked through the woods, taken many years of football,soccer games on dusty fields, and many other non friendly environments for push/pull Len's. I never had any problem with dust getting in the Len's as many posts suggests it's a dust sucker also imop while holding the barrel with the left hand supporting the Len's it's easier to find your subject zoomed out then zoom in while still supporting it, as with the twist to zoom you're using two maybe three fingers and having some wrist action to zoom and loosing some support. My 70/200 version 2 is twist to zoom wish it is push/pull. If Canon ever comes out with a 100/400 push/pull
version I'll be the first to order it, you can't beat the new glass that is out there!!

With the Canon 100-400 it's not even a question, IMO. The Mk II is noticeably superior to the Mk I. Unless you can not afford it the Mk II is the only one to spend your money on. I have never used the Tamron or Sigma, but I have never seen a serious claim that either is superior to or even equal to the 100-400 Mk II.

Yes, some were lucky enough to have a lock. There were some complaints about the fact the lens was locked when they wanted to zoom. For me, I would have liked to have had the lock. Even though the push/pull I owned did not have a lock, and did not creep much, it was still more creep than I wanted it to.

Yes, Canon are the kings of telephoto, that's well-known. But you have to be able to afford to buy L.
I have had a non-L Canon lens virtually fall apart and crumble in my hands.

Exactly. It works great as the tension is adjustable to suit the user.
