Lens aperture adjustment
Sep 5, 2013 15:37:48 #
On my Canon 60d, I'm using a 70-300 4 to 5.6 lens. When shooting in manual mode the lowest I can get the lens to go is 5.6. How can I adjust it to 4?

What the settings mean is that at 70MM your lens will open to f/4 but when it's at 300MM the maximum opening is f/5.6.
I suggest you turn your lens to 70MM and try again.

Mike, fraid so. Joe is correct, you have what is called a "variable aperture" lens. It's light, or speed if you will, drops off as the lens gets longer.
If you set it at f4 at 70mm, it will get slower as you zoom out. But it will go back to f4, if you go back to 70mm.
Maybe what you need to look at are one of the "constant aperture", lenses. They will stay the same aperture throughout the zoom range.
Good luck. SS

Thank you, SS. Would a constant aperture lens be the Canon 70-200 2.8 L lens?
Yes!

Yes, and the one that truly hurts when you crank the ring to full open.

Would that be aperture or sink hole? My late wife had other words for that. :lol: :lol: :lol: :lol:

Perhaps a vacuum?
No matter how much you have saved up, there is always something you would like better that's just beyond your budget.
I can still hear my mom repeating my words when I was in high school "It's the last camera I'll ever want". I got a Mamiya C-330 for my birthday my senior year. Cost $180 brand new at the base exchange. Love it, but it was definitely NOT the last camera I ever owned.
To the topic at hand, one thing you gain with constant aperture lenses is that the build quality is almost always top notch. All the zoom lenses I use the most are constant aperture. I have a few that aren't, like the Nikon 16-85. Convenient range, lightweight but when it counts, the 24-70 2.8 FF or 17-55 2.8 for DX are my go to lenses. They focus faster, more accurately and are sharper. (And more expensive)

I couldn't agree more. I have a very good 70-300 'L' lens but then a bunch of primes which do everything you've just described. For a landscape on my full frame I have a 17-40, f/

Joe, I did learn a great deal shooting a football game last night I used the variable 70-300 lens. I shot mostly in manual. It was a pain to continually adjust ISO Then I set the ISO to Auto and didn't need to mess with it. Sort of semi manual.
