Should the Auto White Balance be left on when using this lens, or should it be switched off?

Hi Kelly, yes Auto White Balance works the best with the Red filter. If you adjust the white balance to 3000K, 5000K, or 6000K and it will make underwater videos warmer, and at every depth change the colors will be different (in a negative way) due to red and orange light loss. When Auto White balance is on, the camera automatically will adjust with the Red Filter on to depth change.

Work how? To set the white balance for a flash or strobe? if that is the question then yes! This thing is not magic it is a neutral color light filter just like the white dome on the Sekonic or old weston incident light meter. The is tone is neutral gray. Now if your question is will it set WB for a TTL flash set toauto every thing the ANSWER IS NO!. If you are bent on auto TTL flash metering then your WB needs to be set for flash on your camera or auto shoot on raw and use a good post software to tweak your color shift if you have any.

You lose auto focus and most auto exposure. I have an *istD and the focus indicator works when I manually focus old K-mount lenses. I had to make some changes in the menus to make this happen, your mileage may vary. Otherwise you'll essentially have a digital camera with stop down metering. The camera has no way of knowing what aperture the lens is at so you need to stop the lens down then let the camera set shutter speed. Again, you'll have to play with your menu settings. Look for Pentax forums on places like photo.net. I think auto white balance should be OK. I use a number of old K-mount and screw mount (with an adapter) lenses. I've had a problem with blurring of bright objects with one of them (a Pentax 1.4 50mm), sort of like a soft focus lens. The same lens is perfectly sharp in a film camera. I think the problem is light reflecting between the rear lens element and the photo sensor. Digital lenses have been designed to deal with this. Be careful if you buy a screw mount adapter, some won't allow infinity focus. Get the genuine Pentax item. It works properly and is easy to remove without using a tool.

Point and Shoot cameras close their lens automatically every time they are turned off, in which case the lens will not get dirty. Why would you carry the camera in your pocket without turning it off? These cameras generally turn themselves off, closing the lens, after only a few minutes.

Hi, you can do both. When in auto, its only an auto/off mode, whereas in P mode, you can also set it to "always on" and "slow synchro". Slow synchro "keeps subjects and distant backgrounds brights".

I'm not having any color casting problem at all. I would think using a grey card would correct it, or set balance to the flash setting if its not already. I have been just shooting auto white balance. What I find most helpful is U-tube tutorials: it's how I learned everything about my camera, speed light, strobes and softboxes!

It's like any other modern 70-200 f2.8. If you set it to f2.8 in manual it will stay there. In auto mode the camera will change shutter speeds and aperture to suit conditions.

I have the same equipment. The situation you describe is not normal in any lens mounted in any camera. But this combination lens/camera use to do it. Put the lens and the camera on manual focus, because the autofocus in this lens on this camera is a nightmare. But in manual mode, this lens is pristine, wonderful.

Hey how are you. I would recommend a wide angle lens to minimize you touching the focusing ring and making the stabilizer wobble. For the price, I can honestly say this is one of... If not the best you'll get. Comes with a nice carrying bag, weights and the stabilizer ready to go after balancing. Any other questions feel free to contact me.

There should be a switch on the cord with an on/off button. Or try turning the lens.

I have noticed the color balance sometimes shifts in unnatural lighting conditions, i.e. when I was filming in a room with outdoor light coming through the windows mixed with fluorescent lighting. But the solution was to switch off the auto-white balance and set it manually; then it worked fine. But in other situations, with one consistent type of lighting, I didn't experience that shift. But yes, it does shift during recording in certain situations when set on auto.

Default is for Steady Shot to be on. Go to Still Image menu 2 and you will see Steady Shot and just turn it off as you would if camera were on a tripod.

You might want to make sure you have the AF turn on both the camera body and the lense. They are two separate settings.

The answer by Dagmar Miura is mostly correct and the exact issues I experience with this camera. Setting white balance to manual doesnt solve "all" the problems of white balance and color shifting but helps considerably. There is still some color shifting when panning through rooms with mixed lighting conditions that I cant seem to avoid. Its not enough for me to call this camera junk because I use it often and have owned it for a year but it is somewhat irritating.

There is a lock somewhere outside the lens near the body. This might prevent you from changing the focal length.

you can set it to auto or man its a switch on lens As for as usm its my understanding this is found on high price lens only

supposedly. it does not have anything in the menus so i don't think you can turn it off but p.148 in the manual says it has "lens-shift type optical stabilization"
