Can you turn off the IS on this lens or is it automatic?

Yes, you can turn off the IS. The new version II super telephoto models (such as this one) have a new additional IS mode that will only activate as you trigger the shutter - the image in the viewfinder will not be shaking about while you're sighting things up prior to taking the shot as was the case in older models or other IS modes. Hope that helps. Mark

i believe this is a manual only lens. change the aperture by turning the aperture dial on the lens itself.

This lens is manual. the aperture is controlled by the ring that is in the lens and not the camera.

the lens does not allow you to fine focus manually in autofocus mode. you would have to set it to manual focus.

Thanks for the explanation, Les. So, it seems that as long as the IS is turned on, in-camera, it doesn't matter whether it's on or off on the lens. I made do some A/B testing to see if there's a difference with the lens switch on/off while the setting is switched on in-camera.

Don't quite understand the question but I have the Pentax version of this lens and it can operate in manual or auto focus. Just flip a switch.

You don't have to tell it to turn OIS off. For all Oly bodies up to the E-M5, there is no way to turn OIS on for lenses having no OIS switch on the lens barrel. Since the 45-150 lacks such a switch its OIS will always be off on an E-PM1. For the two latest Oly bodies (E-PL5, E-PM2), OIS can be enabled even for lenses having no OIS switch on the lens barrel.

No it has a manual F-stop. Almost all manual F-stop lenses do not auto focus. It's a film lens, if you are shooting film why would you want to auto focus. The mic will pick up the noise. Manual F-stop lenses (most of them anyway) do not carry chips inside them that communicate with the camera. The point of the manual is because that's how film lenses work.

yes, the camera is supposed to this. i think this is a sound coming from the lens shutting, and cannot be turned off, i looked for it in settings..

This is a purely manual lens. It does not auto focus on any camera body. If you buy the chipped version of the lens, you can set aperture from camera and you can see the green dot in view finder that helps in manual focusing.

It is manual focus. You can beat the price. The quality is good and it is a super-big zoom lens.

You should turn off the Sigma OS when a tripod is used. This Sigma 17-50 lens does not have a sensor that automatically shuts off the OS under these conditions.

Option 1:You have to switch your camera into manual mode. You then set the aperture manually and remove the lens before turning off the camera. Option 2: purchase an aftermarket aperture ring that closes the aperture down.

It is a manual focus and stop sown method exposure lens not made for automatic cameras. It can only be used with cameras that allow for manual modes. Thus it is not a lens for those not inimaty familiar with their cameras and how to use such a lens. It does not have anything to connect it to a camera for automatic function. It is for modern Nikon cameras a completely manual lens. I hope this helps.

You can manually adjust the aperture or allow the camera to set the f stop. As far as auto focus the lens does have a motor

Shawn, Yes this is an auto-focus lens. The focus-by-wire manual option isn't nearly as useful as its inherent auto-focus abilities. If you have this lens on a camera on a tripod, remember to turn off all the anti-shake features.

Turn off TRU-COLOR. then you get a settings tab there you can turn off the annoying and useless autofocus and mess with other settings as well.
