Re: instuctions for opteka 650-1300 lens for use on...
Try turning off the shutter lock.. In my Dynax 7D manual it tells you to turn off shutter lock when attaching to a telescope or microscope this is what this lens basicly is .The shutter lock is turned on and off in section three of the custon menu on my Dynax ,check your manual for your camera to find out where to turn on and off shutter lock, hope this helps

First, make sure that you have the right adapter to couple this lens to your Nikon. A universal adapter may actually fit and properly click into place but the electrical contacts may not match your Nikon. Make sure the electrical contacts on the adapter match the contacts on the camera body.
If they don't match, get an adapter specifically for Nikon and perhaps, specifically for your camera.
Once you have verified that it is a Nikon adapter, you need to make sure the electrical contacts between the adapter and the camera body are clean. Many people clean the contacts by holding the lens release button down and twisting the lens or in this case, the adapter, on and off ten or more times.
If neither of these options work you may need to contact Opteka, Nikon or both.
When you go to the Opteka page here http://opteka.com/500m.aspx
You can select "options" for the camera company (there are 6) which you have. It may mean that the lens uses an adapter for the different pin and thread patterns, so the lens if bought new will fit with the selected option, a used one, you may need to get an adapter.
Best bet is to try before you buy.
you need a proper t2 adapter. when you remove the m42 adaptor on tair lens, you can attach the proper t2 to nikon adaptor on it. check my tair 300 photo. it has "t2 to m42" adapter on it. please be sure that find the correct adapter. i bought several adapters to find the correct one. one of them was different than t2 adapter but looking alike and sold as t2 by seller. it is hard to find the correct adapter. i guess there are variants of that standard(which is odd).
It can be used with a Sony DSLR however you'll need to buy a a T mount adapter in order to get it to work. You'll need to buy a T-mount Sony/ Minolta adapter. Look here to see what it is you need http://www.bhphotovideo.com/c/product/601244-REG/Vivitar_650_1300mm_f_8_16_Manual_Focus.html
The lense will probably work with an adapter. try ebay. i purchased one for my canon lenses for macro work. note that the focal length of the nikon is 46.5 and the minolta is 43.5 and infinity will not work with out an adapter with a correcting lense. you will find a adapter with out a lense will work fine for macro.
The Sony ALpha camera actually use a Konica/ Minolta lens mount. a 500 or 1000mm lens won't have any really mechanical connection to make, so if you can find the lens with a Minolta mount , it should fit. BTW- most of those long lenses require a T mount adapter to fit on ANY camera-
You need to turn the mode dial to Manual (M). You won't be able to use the camera's built-in exposure meter at all with this lens. You can take an exposure reading with another lens to use as a starting point, then review the pictures and histograms to fine-tune the exposure.
Depending on how new your Minolta SLR film camera was, the lens may or may not work on a Minolta Digital SLR. In many cases, a lens with the correct mount (in this case, a Minolta mount) can be used on the same brand of camera in the digital format.
One thing you should know is that DSLR sensors are, generally speaking, smaller than the size of a 35mm film negative. Long story short, that means that your lens will have a magnification factor on the DSLR. Usually, it is in the range of 150%, so a 70-300 lens from a film camera would cover 105 to 450 on a Digital SLR.
To be sure about the mount, you'll need to seek advice specific to Minoltas -- probably best to take your lens to a local camera shop and see for sure if it fits and what features will work (aperature, auto-focus, etc) and which won't work on the DSLR.
You may be able to find a Konica toMinolta or Konica to M42 adaptor. Some adaptors are available...some aren't; it depends upon the film plane dist. and mount diameter. For instance you can get a Nikon to Canon adaptor, you can't get a Canon to Nikon adaptor. Email KonicaMinolta and ask them.
