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.

How do I get my Nikon d5000 to recognize the lens with extention tubes?


Without any electronics the camera cannot recognize the lens. Set the exposure mode to "M" (Manual). You'll have to set both the aperture and shutter speed yourself.

You'll also get no exposure assistance from the camera's light meter. You can review the picture after taking one and/or use the histogram to tune the exposure.

My Nikon D5000 isn't recognizing my Sigma 35-105 lens. Why?


Is this an older manual focus lens? If so, it lacks the electronics to communicate with the camera. You have to set the camera to Manual exposure mode (turn the mode dial to "M"). Set the shutter speed on the camera body as usual and set the aperture by turning the aperture ring on the lens. You'll have to set the exposure without any help from the camera's light meter.

Vivitar 84mm 1.4 aspherical on Nikon D80


If you mean the 85mm, it's not an autofocus lens. Nor does it have the electronics to communicate with the camera. You need to set the camera to manual exposure mode (turn the mode dial to M) and set the exposure manually. Set the shutter speed by turning the command dial on the back of the camera and the aperture by turning the aperture ring on the lens.

Again, this is a manual lens. No auto-anything. But it's a nice fast lens, with shallow depth of field when you want it.

We cannot zoom in or out on the lense and the have to focus manually , this occured after our 9 year old daughter used the camera, did she just switch some sort of adjustment that locked everything up??


What you can try is this. Turn the camera off. Remove the lens.
Put the lens back on, turn on the camera. note any messages.
You should read your manual.
You may be set in manual mode on the camera or the lens or check both.
Make sure that the camera is set to auto lens in menus and on the camera, if it has a setting on the outside.
Make sure, if the lens is AUTO, to set the switch to auto.
Hope it works.

The lens no longer works on auto and as I wear glasses, I can't manually focus it.


Try cleaning the contacts on the camera body and lens where they meet with a cotton swab lightly dampened with rubbing alcohol.

I can get my 50mm lens to work with my d70 nikon.


If the lens has an aperture ring, make sure it is set on the largest f number. Make sure the lens is mounted fully on camera. Oherwise an AF 50mmm f1.8 lens should work on a D70 with no problem

Auto focus on my SLR doesn't work


I have this same lens and it focuses at all focal lengths and with all settings except :"manual." Be sure that the setting switch on the lens itself is not set to "M" (manual).

Tamron 90mm 2.5 adaptall man focus lens


You probably have to set the aperture manually on the lens, because it might not have CPU contacts. I think changing the aperture on the camera will probably have no effect, so just try twisting the aperture ring to wide open.

You usually have to set the aperture at the minimum setting (highest number) so that if the camera is choosing the aperture, it can stop down to the required value.

No good having it set at f2.8 if the shot needs f11.

If the lens is very old, it might have a manual iris that you have to set yourself on the lens. The lenses that stop down automatically will have a tiny peg on the mount that a suitable camera can operate. Gentle pushing of this peg while looking through the lens will tell if it is stopping down - set it wide open first.

If you have a depth of field preview button, this will also have the same effect with the lens on the camera if the body matches up with the lens.

If this is a manual focus lens, you will need to do two things (and an optional third thing.)

1) On the side of the camera, you have to switch the focus mode switch from "AF" (Autofocus) to "MF" (Manual focus) . . . Yeah. I know, you probably already did that. <grin>

2) When you press Menu, go to the Custom Setting and change the Allow aperture setting to on, so that the Pentax K100D will then work with manual control of the aperture ring. You need to do this or the K100D will not work with manual exposure lenses (M lenses) or even autoexposure lenses (KA, KA2, FA, etc.) when you move the aperture ring from the "A" position to one of the manual aperture settings!

3) This is optional, but in the Custom Setting you can also turn on the Fl in manual focus mode, so that even though you don't have autofocus capability, you will get a beep indicator when you have successfully managed to manually focus your lens.

I have a few nice manual focus lenses that I have a lot of fun playing with on my K100D.

Take care & Happing Imaging!
