L110 also? Does the filter need to be taken off when you turn the camera off and the lens

No. Keep in mind though, the stock lens cap that came with your camera cannot be used to protect the filter from dirt and scratches. You will need to obtain a 67mm lens cap to do that.

Michael, I cannot respond to the "110 also" question. I suggest that part of the problem has to do with the placement of the flash, and the resultant shadow that the filter extension/barrel throws as a result of being directly 'downline' from the flash source. If the flash had been located to the left or to the right of the camera, perhaps it would not be an issue. ---------The barrel is tightened at a point very close to the body of the camera, and was not an issue when the lens retracts. --- Hope this helps.

I would not personally use this kit for any camera other than the L120. The adapter fits just right with the length the lens extends on the L120 for both zooming and close-ups and it would not match for the L110 as the zoom is different. If you are using the L120 the filter does not need to be taken off, as the adapter is the right length to allow full zooming of the lens without the need for removal. Hope this helps.

You would probably have to take off the case, it all depends on how the lens sits over the case... I used to take mine off but I discovered that I could actually leave mine on while taking the photo.

Haven't had that problem. The manual just says turn the camera off and check the connection. I'd worry that the lens electronics were damaged.

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.

Yes. it does so in mine also. I think it is when you turn it off or you deactivate the AF that the lens probably detaches something inside.

I have seen it recommended, although I generally do not, with no ill effects so far. I worked as a wedding/event photographer for 10 years, never once turning a camera or lens off to swap, and never had a failure. It is important to turn OS off if the camera if mounted on a tripod. Small vibrations are amplified, fooling the sensor into thinking there is more movement that exists. This will degrade your image quality.

I have taken mine off since I spent more time removing it to get various shots than keeping it on. But that's my way of taking photos. Perhaps it would be different for you. At the price, it was worth it to get the filters even if the hood didn't work out so well.

Counter clockwise is the correct way to remove the filter. I would stop into a camera shop and let them look at it. They may have better insight by having it in their hands.

No, it just clips on the end of the lens. However, it doesn't interfere with placing filters on the lens itself.

You can get a filter, but the depth of the lens hood obviates the need for it. I just got back from Australia shooting with the lens in all weather and conditions and did not use a filter. Better images that way as well.Regards,Evan

No, because of the len's curve and the hood, there is no room for a filter. I don't find this as a problem. For the price and results, this is an exceptional lens. It is worth every penny. Learn to work with the parameters and you will be pleased with the results.

Theoretically no, but I prefer having a filter on EVERY lens I have at all times. That way I don't have to worry about making switches, or ruining a lens without a filter

On the D80 you have to prefocus before using the filter as the D80 has no live view and you cannot see anything with the filter attached, AF and metering do not work either. That required the camera be tripod mounted and all auto functions set to manual. It is much simpler to use it on a newer camera with live view mode such as a D7000.

The lens is covered when you turn the camera off, and opens when you turn it on.

Yes it does. I would never consider using a non-multi-coated filter on a digital camera. The reason is simple. The sensor has a flat glass protecting it (called a low-pass filter - LPF). Some light will bounce off the LPF and head out the lens. Since lens elements are multi-coated and curved, very little light will reflect back to the sensor. But since the front filter IS flat, you can get a lot of light bouncing back. If you use a non-coated, or single-coated filter, you get a lot of light reflected back into the sensor. This shows up as a loss of contrast (veiling flair) or as ghosts and hot spots. Multi-coated filters are designed to reduce this effect, but cannot eliminate it. This is a real problem when you shoot into a light source. When shooing into a light, ANY filter will degrade the image. Multi-coated filters are much better, though.

By default it would appear that on the Sony A100 like my Sony SLT-55a is configured to prevent the shutter from opening when there is no lens attached to the camera. Using manual lenses, lenses with out the electrical contacts to talk with the camera, requires the changing of some menu settings with in the camera to allow the shutter to be actuated with or without a lens. The manual for the Sony A100, available in PDF format from http://www.docs.sony.com/release/DSLRA100.pdf, on page 96 refers to turning off the shutter lock in "Custom menu 2". I suggest that once the photo shoot is done with the manual lens to turn the shutter lock back on prior to removing the lens in order to protect the sensor behind the shutter. I trust this information is useful.

Short answer: yes. Generally always better to turn the OS on any lens off when using a tripod, if nothing else it uses less power that way.
