I bought this with a Celestron spotting scope. Does the camera's auto focus and metering work with this T-Ring?

No. Auto focus cant work because u must put camera mode to manual , the "lens" is the scope, you must focus with the scope. Be sure to realize a collimation process to your scope , if needed, to get better results, better pictures.

Metering I'm not sure, but not autofocus as it is a fixed attachment. Use your scopes focus.

Metering does work, but aoutofocus will not, the camera needs to be put in manual control to it to work correctly

It does auot meter, but it will not auto focus. Focus is done is done with the telescope.

No auto focus and metering may not work in the auto mode if you are connecting the camera body directly to the scope without any lens on the camera. It is best to focus in a manual mode for any camera attached to any scope directly. I have a Celestron CPC Deluxe HD 1100 and a Nikon D800 that I mount directly to the scope using a T-Ring and T-ring Adapter and the camera will not auto focus on images.

I have no clue, as this is intended for telescopes. If it works for you, I took the measurement with a caliper on the inside thread and it is 49.5 mm (1.95 inch). Hope it works. Remember you also need the respective T-Ring for your camera.

No it will not work. You need to purchase the T-ring specifically designed for a Nikon camera. They cost about the same.

As per previous answer it is just standard adapter for a camera specific T ring so you can attach camera to telescope that has 1.25 eyepiece It will not give more "strength" (I assume you mean magnification).

Im not exactly sure but one thing I know for sure is you will need a reducer. This camera will magnify the image the same way a 5mm lens would. The big question you want to know before you buy this is if your telescope can move the camera close enough to the focal plane.

That isn't how this is designed to be used. This just threads into the T Ring for prime focus. For what you are wanting to do you most likely need a zoom eye from Celestron that has the T Thread built in under the eye relief for example Celestron 93230 8 to 24mm 1.25 Zoom Eyepiece .

Hi there it works for me , im using Olympus omd5. play with it a bit ,move ring sideways and backward .

The adapter will fit your Canon T3i But from looking at your spotting scope it will not fit it. This product is designed to connect a camera to a Schmidt-Cassegrain astronomical telescope. If the eyepiece on your scope is removable and it is 1 1/2" in diameter it might work but you will not get a whole lot of magnification from it. You will probably be better off purchasing a telephoto lens for the camera.

You will need a T-adapter as well as tne Celestron 93230 8 to 24mm 1.25 Zoom Eyepiece (this eyepiece is the only eyepiece that allows you to focus and change the focal point for your camera which is mandatory for higher end cameras. Note: This scope is not meant for astrophotography but is still a very nice telescope for the price.

I really don't know but I can tell you for a couole bucks more you can buy the celestron zoom lens that has a threaded eyecup so you can directly attached a T2 adapter and camera to the lens itself. I tried this item but it was just too large and wonky.

Mine works fine with tamron and bower teleconverters - with some you need to make sure that the contacts are absolutely clean, and the loss of aperture means that auto focus most likely won't work. But if you're happy to focus manually you should have no problem.

It does have a focus ring but I was not ever able to get anything in to actual focus when trying to take a picture.

I haven't gotten mine yet, but I ordered it. I think I read that the silver ring on the front of the lense is how you adjust the focus...give it a try! If it doesn't work, contact the seller or something.

It will fit on the, but will be manual focus only, and you will need to set it up using "non cpu lens data" in the camera menu in order to get it to meter

If the Tamron has the Adaptall II mount (not a fixed Nikon mount) this works nicely. If you have an aperture ring on the Tamron then you can use aperture priority auto mode with stopped-down metering. Or full manual metering.

As long as you Canon fits any of the interchangeable Canon lenses, the T-Ring will work. But if you are planning on using it with a telescope, you still need the 1.25 inch T-ring lens adapter that the ring fits on to.

Search Amazon for T-Ring or T-mount adapter. Have a search on Google too. You have to buy one for specifically for the Minolta/Sony mount. I think Celestron do them themselves too.
