What is a T-mount adapter ?

Archived from groups: rec.photo.digital.slr-systems (More info?)

I was looking at a Quantaray 600mm~1000mm zoom lens and it indicated it needs a T-mount
adapter.

Can anybody describe what this is and any model numbers I can look-up for Canon ?

Thanx...

Thanx Bill. That fills the picture "almost" completely.

Can you explain what the adapter is ?

I do appreciate the URLs. I bookmarked the EOS URL.

What you are describing might be "C-mount", used for video since the
1960s.

According to:
http://www.fli-cam.com/FLIsupport/tmount.htm

Tamron introduced T-mount in 1957 as a universal lens mount for 35mm
cameras!

Sorry, I don't have a clue.

When you posted your inquiry, I thought perhaps the lens in question was
made for a mount other than Canon and you were looking for something to
convert it to a Canon EOS mount. So I went and looked at B&H and you see
what I found. However, I don't think the Bausch & Lomb adapter pictured
actually does that, I'm not sure what it is supposed to do. Since you
wanted it, I thought you would know. :-)

Let's go at this from the other side: What do you need the adapter to
do? You mentioned a lens that needs a T-adapter. Why does it need a
T-adapter? To attach the lens to a Canon camera? To attach the lens to a
telescope?

| The OP wanted it for this lens:
| http://www7.ritzcamera.com/product/29925
|
| The lens has a 42mm thread. To fit it to a camera one need an adapter
| to whatever type of bayonet mount the camera has. After you've fitted
| the adapter, the lens looks and behaves just like a lens with a
| bayonet mount. If you look on the suggested "accessories" on the Ritz
| Camera page, you'll find of lists of T-mounts for all major SLR
| mounts.
|
| To get the right adapter for a Canon dSLR body, you don't need a
| "model number". Just get the EOS-version of the adapter and that's
| all there is to it ...
|
| (The T-mount is pretty standard, but for a Quantaray lens, I would get
| the Quantaray adapter.)

The lens or the adapter?

I have no first hand experience of the lens. But I am sure you're
aware that Quantaray is RitzCamera's house brand and that the lenses
sold under this brand is made by others. Ritz want $350 for this zoom
which is at least $100 too much. Looking at the specs, it is obvious
that it is a rebranded version of the Vivitar Series 1 600-1000mm
f/9.9-16. The Vivitar version sells for $250 in most places ($300 in
a package from B&H that includes the EOS T-mount adapter and a 2x
teleconverter). At this price point, you can't expect top class
optics.

As for the T-mount adapter, I use one to connect a Sigma 500mm mirror
lens to a Kodak DCS-460 (Nikon mount) - and that works fine.

You should be aware that with a T-mount, you'll shoot fully manual -
but as far as I know, the 300D has a fully manual mode so that should
not be a problem.
