Is the T/T2 mount the same as an M42 mount? I want to connect my Nikon to my Questar standard.

I am not sure what the M42 mount is and I don't have a Questar telescope, but this mount adapter (T-ring) connects without a problem to my Nikon D5100. https://www.youtube.com/watch?v=reFxoF3XoaU

Good Question. At ONE Time & for a long time there was no doubt. Nikon had a rep. for everything being compatible. No more. NOW the only way is to try it. The mounts should be the same, but the electronic features may OR may not be compatible.

This adapter allows you to attach to a standard 'T-mount' threaded connection to the Nikon proprietary lens mount. So any lens (or other component) threaded with a 42 mm diameter, 0.75 mm thread pitch can be attached. In theory you can mount any camera body to any lens as long as the T-mount adapters are available for the specific camera body and lens. Wikipedia has a good explanation of the T-mount if you are unfamiliar with them a thttp://en.m.wikipedia.org/wiki/T-mount.

Yes it is interchangeable. I use all my lenses that had my T1 and they work great.

No, this adapter is for m42 screw-mount lenses. You need to know what mount your Tamron is and get the correct adapter if the lens is not a Canon mount. Just search for 'tamron af to canon adapter'.

I bought it last July 2012 and it works perfect with my T2i but make sure ask the seller if it comes with M42 screw mount adapter or you can buy it separate.You'll fall in love with this lens.Best for closeup, portrait and video.

More strength? If you could explain I might be able to answer. This is a standard adapter for your camera-specific T-ring. You need both to mount/use a camera with a telescope (unless you get real lucky shooting through an eyepiece) - I've used them with heavy film cameras with no problem - on a decent telescope. If the 'scope is lightweight it's probably not good for astrophotography anyway. But the "strength" issue is unclear - are you planning on some other kind of use?

Yes, this will adapt T or T2 mount lenses to any Nikon F mount camera. You will maintain infinity focus but there will be no automatic functions, totally manual focusing and aperture.

I believe this was sold as a fixed mount lens, not an Adaptall II lens, and it came in a Nikon mount. If you don't mind my asking, why do you need to use an adapter, are you trying to remove its fixed mount and convert it from another brand of mount to Nikon?

Not a crazy question as there is a lot of confusion out there between "M42" and "T2". When someone says "M42" they typically mean 42mm 1.0 pitch (the old Pentax Screw Mount). When someone says T2 they typically mean 42mm .75 pitch. Many sellers don't even know the difference and interchange the two terms. This item is 42mm .75 pitch.

I do not see this as being compatible with your lens as listed on the NIKONUSA site.By the way, Nikon is releasing an updated version of this TC on August 28th.http://www.nikonusa.com/en/Nikon-Products/Product/Camera-Lenses/AF-S-Teleconverter-TC-14E-II.html

With a standard hot shoe mount (which the T3 appears to have) you should have no problem. The T3 does NOT appear to have a sync port, which is why the sync cord won't work. Many beginner level DSLR's don't have a sync port.

I bought one and it doesn't seem to fit anything I have. I have a Nikon D40 and a Vivitar zoom that uses a TX adapter. That's what I had on my Canon A-1. This T mount doesn't fit anything I have. Sorry.

I have several Canons and they all mount fine. You simply remove the eye shade from the scopes eyepiece, thread a small ring onto the eyepiece, then thread your T-ring and finally your camera to the T-ring. Now you have a very large lens mounted to your camera. Just remember to purchase a T-ring compatible with your specific model camera. Different sensor sizes requires deeper T-rings to avoid vignetting. T-rings don't cost much, I've seen quality name brand models as low as $16. BTW, mirrorless cameras also work great with these scopes. Good luck!

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).

Yes - this adapter is designed specifically for the M42 screw type. It works just fine on an old Tokina lens that was mounted on my father-in-law's 1960's Pentax. Make sure, however, that you get the Version 2 adapter upgrade from FotoDiox. The Version 1 adapter from M42 to Canon EOS did not make provision to disengage the aperture shaft in some M42-type lens. FotoDiox was very responsive, and I had great customer support from them. Again, make sure they send you the Version 2 M42 to EOS adapter.

Technically, it will fit (the actual fitting/connector is a standard camera mount) but the weight of the camera and a lens will push you right up to the limits of the product. There are ways and weights to add to expand the capability; the product is rated for cameras up to 2 pounds - your T2i camera body, without a lens, is 1.2 pounds. For occasional use, you can make this work; for professional use, you'd be better off looking for a more capable product. I have used mine with a much smaller camera and have had great results - so please don't misunderstand my previous comments as a negative review of the product. If you have follow up comments, I'd be happy to respond.
