How can I find out the settings available on a Quantaray 70-300 mm zoom lens?

Quantaray has made several different 70-300mm lenses so I'm not sure exactly which one you have. However, if the lens doesn't have a AF/M switch it's no big deal. Assuming it's an autofocus lens, it's always on. If you want to switch to manual focus, flip the switch on the camera body.

If it's an older manual-focus Quantaray lens then the question is moot.

Why does my lens only zoom to 200

Could be, because most camera's only can auto focus till f/1:5.6. And if 5.6 is reached at the focal length of 200 mm, the camera stops it from going to a part it can't be focused.
Perhaps you try the lens in manual focus, and manual zoom.

My canon 18-55 lens will only take a picture in wide angle. as soon as i try to zoom at all it won't take a picture. it is 4 months old and hasn't been used much. and i haven't dropped it. any suggestions?

The Auto-Focus on the lens is damaged. I have had the exact same problem with my 18-55 and I ended up buying a new one because I take shots at weddings and I can't afford to manually focus each photo. You can still use it if you switch the small knob to MF and then use the focus ring for manual focus.

Good morning. I have an old Canon WF-M camera with a 28-200mm Quantaray lens. I am thinking about buying a Canon EOS Rebel T1 EF-S. Does the lens work with the digital camera ? Or this just fits the old...

The older lenses will work with the Canon digital cameras, but they will be manual focus and you will need an adapter. The adapters are available at camera shops like B&H. I use some older lenses for macro.

Auto Focus not working for Canon EFS 18-55mm lens

This usually happens when the contacts between the lens and the camera are dirty. Try taking the lens off and cleaning carefully the metal contacts on the camera and the lens. If that does not solve the problem, you can get a warranty repair or replacement since that camera should still be under the original 12 month warranty.

I need a manual for AF 35-70mm f2.8 D zoom nikkor - no idea how to use this lens.

i was not able to find a manual - this review may help
The lens consists of
  1. Zoom
  2. Focus
  3. Aperture
  4. Macro
1) Zoom - this is by push pull - so you push the lens out to wide angle 2) To switch to manual focus - will need to be done on the camera and then you can use the front control ring to focus - 4) also you can use the button to switch to macro mode - BUT only with the Zoom at 35mm - lens fully extended 3) You have an aperture range of 2.8 - 22 this varies the amount of light allowed into the lens - 2.8 is the most light - F4 to F5.6 to F8 - each change halfs the light allowed in - so changing from F4 to F5.6 half the light

I have a Tamron 28-200 lens for my Canon EOS 20D. My brother took it to Africa, and since it's return, the lens will no longer zoom out by turning the zooming ring. I spoke to another photographer who...

Some of the long tele's like that have some sort of locking mechanism on the side to prevent lens creep. Look for switches other than your aperature lock and auto focus/manual switch.

Manual Focussing failure with Canon EF 100-400mm SLR zoom lens

I doubt if there is anything you can do yourself. The manual focus may have debris under the ring or is in need of parts. I would leave this one to a tech.

Trouble focusing with sigma 70-300 DL macro super lens

It will not focus on anything closer than 5 feet.

(From Sigma lens literature)
Capable of macro photography, this lens has a 1:2 maximum close-up magnification at the 300 mm focal length. It's the ideal high performance lens for portraits, sports photography, nature photography, and other types of photography that frequently use the telephoto range. It also has a switch for changeover to macro photography at focal lengths between 200mm and 300mm with a maximum close-up magnification from 1:2.9 to 1:2. The minimum focusing distance is 1.5m / 59 in. at all zoom settings.
