Pre-set depending on the model, can be fixed aperture, and or fixed focal length. You have to read the spec sheet to know, or call the dealer.

I have a fixed 500 mm / F8 mirror lens. It is refered to as a fixed lens, because nothing is adjustable. I have aperture and filter drop-ins to do the equivalent of some adjustments.

Looking for a lense support for a quantaray 75-200 mm lense


what do you mean, lens support? - a 75-200 is not usually long enough to warrant this, if you mean a support bracket to mount the lens to a tripod, instead of a camera mounting point?

btw - sigma made all or most of the lenses for quantaray, so you might try looking this one up that way as well.

THE AF AND MF ON THE LENS MEANS WHAT


AF=Auto Focus. With an autofusu capable body, the camera will automatically focus for you using preset focusing zone. Move the Switch to:
MF and it becomes a manual focus lens, where the photographer has to manually focus on his subject.

What does a kalimar 500mm F8.0 preset lens with tripod mount,what cameras will it fit? thankyou,bear.


The lens in question is not brand specific. Instead you use T2 mount adaptors to fit whichever SLR camera you wish to use with it.

T2 mounts can be purchased widely online, just choose whichever one fits your camera mount.

What is the middle wheel (says macro) on my lens


If it says macro, that means focusing at a close-up range, maybe just a couple inches or centimeters- your lens specifications will tell you exact distances.

I have a quantaray 500 f8/1000 f16 lens i inherited from a relitive and i'm un sure on how to mount it with out the 1000mm converter


Although I'm unfamiliar with the lens which you have, many generic mirror lenses like yours use a T-mount adapter which screws onto the lens to provide a suitable mounting for your camera body.

Check the converter, it probably has the T-mount screwed onto it.

Nikon d40, t-mount adapter, showing error no lens attached.


You'll need to switch to M (Manual) mode. You won't get any metering through the lens, nor will you get any autofocus.

Hi there my D40 doest want work with this lens its saying lens not attached why? its only working on M profile. is that fault or is it ok? thank you lots


It seems perfectly fine. The lens lacks the circuitry to work with the meter on the camera, and thus must be used in Manual mode. The meter does not work, either, with this lens.

Front focus problem


Hey hubro,
This switch is used to set a focus point to so you can quickly focus to the preset distance. What you have to do is set the switch to the on or on with sound setting then focus to the distance you want to preset and then press the set button. While this switch is set to the on or on with sound setting you just turn the focus preset ring which should be in front of the focusing ring and the camera should focus to the preset distance. I hope this helps!

Sincerely,
Allan
Go Ahead. Use Us.

Auto focusing problem


Your camera is only compatable with AFS-type lenses because it has no screw-drive motor.  You can only use AFS Nikkors and Sigma HSM lenses (the lens actually has a motor inside).  You were misinformed.  Bring the lens back and ask for a refund. Take that money and purchase a compatable lens somewhere else.
