Canon 30d with tamron af 70-300mm di macro lense showing error 99
99' indicates some problem with the AF contacts. This is a common error
in Canon lenses. It could indicate a very simple problem like dirty
contacts or a much serious one like the breakage of USM cable. Alternately, it can also be a card error or camera error.
remove the lens, battery and card and leave the camera like that for
about 30 min. After that, insert a fully charged battery and switch on
the camera. If the error still shows up, it is a fault with the camera
and has to be serviced.
If not, turn the camera off and insert the card. Format the card in the
camera and depress the shutter button. If it shows an error, the card is
If not, try cleaning the lens and body contacts (the metal
contacts between the lens and body) using a pencil eraser. Be careful to
hold the body facing down so that no dust falls inside. After cleaning
both the lens and the body contacts, re-attach the lens and try
If the error still shows up, you need to take the lens to an
authorized service center.

I have a tamron 70-300mm
This is the kind of error which you always risk these days in buying lenses which are not from your camera manufacturer. Error 01 simply means that the camera cannot communicate with the lens. Canon's protocols are not open standards and third party manufacturers have to reverse engineer to produce something which works. As they're working in the dark, they cannot always arrive at a solution which makes all models suit all Canon bodies.
You have two possible solutions:-
Visually inspect the contacts on the lens and the camera body and if they're anything other than clean and bright then use a clean pencil eraser on them. Be very, very, careful not to let any of the rubber crumbs into the lens or the camera body.
If that fails, visit the Tamron website to see whether the lens can be returned to be updated for other bodies. if it can't then sell it and buy a later Tamron model or better still a Canon one. They may cost more, but the results are better and their resale value is much higher.

Shutter isn't opening in the
The SHUTTER IS NOT IN THE LENS. I\The shutter is in the camera body in front of the ccd or cmos sensor. You are talking aboput the aperture blades. Try changing the aperture, of course, unless you have a depth of field preview, you will not see the diaphragm open.close.

Drop my Nikon D100 camera with a Tamron AF
First question "is it worth repairing" if it were mine I'd look to see what a new one is worth then divide that in half (cause that's what you might be able to buy a used one for) then figure about $120.00 for cleaning lubricating and adjusting the your lens. With your lens you know what you have, buying used might need the service. you are the one to decide. As for the second question "can I repair it myself" short answer no. If you have to ask if you can repair it then you don't have the necessary tools and general knowledge of how to dismantle and reassemble the lens (and have it work when finished). The lens took a hit and most likely set the inner and outer lens barrels out of alignment causing the inner barrel to slip out of its seal and or focusing gear and hang things up forcing it will break parts causing more repair costs. All else fails get an estimate before repair. Been there with a lens myself and after a couple a months without bit the bullet and had it repaired. Cheers best of luck

How do i attach my sigma lens to my nikon d300
I'm going to assume the Sigma lens has a Nikon mount. If it has any other mount then it won't fit on a Nikon camera.
Align the mounting mark on the lens with the mark on the camera body (at about the two-o'clock position). Push the lens into the mount then twist the lens counterclockwise until it clicks in place.
It's the exact same procedure you would use with a Nikon lens.
