Don't know A5100. U need to check the A5100 If it's the same as the nex ur good to go with the nikkor lens but auto focus won't work. The other lenses need different adapter

I don't know about "any" Tamron lens, because I don't own any other Tamrons. My 28mm Tamron lens had the "adaptall" type of back on it, and I originally had a Pentax K adapter on it for an old film camera. This particular adapter fit like a charm so I can now use it on my Canon T3. As Paul Syms said, none of the automatic functions work, but for manual use it has worked very well for me.

It's an A-mount lens, so you'll need an A to E adapter. The lens is manual aperture and manual focus.

You'll be able to use all your old Pentax lenses. If they're screw mount you'll need to get an adapter. Good ones (Original Pentax) run about $20 on ebay or you get one from the Pentax Online Store for $30.95.I suspect the metering will work but you may have to change some camera settings. You'll have to stop the lens down, then the camera will set the shutter speed. At least that's how it works with my Pentax *istD and screw mount lenses. If you're using K-mount lenses the same applies. With my camera I do get an "in focus" indicator in the viewfinder when I use manual K-mount lenses.

I don't use any adaptors, I picked up two lens- One for a Sony A37, one for a Nikon D3100. I've used the Sony a lot, there is minimal vignetting. Still a great lens.

I have the D5100 with the AF-S NIKKOR 18-55m 1:3.5-5.6G lens. I find it to be a little tight going on/off but it fits well.

My Tamron 28-300 is for Pentax mount and not the current model. The Nikon mount should work fine with a D5100. I always try to download and read the manual befor I make a significant purchase. That way I am not blindsided by a feature or limitation. Bill

I can't say for sure about your equipment. I can tell you that I have a Nikon D90 and D7000 and older model Tamron 35-135 and 70-210 lenses. The adapter works perfectly for me and allows me to continue using my older lenses that make great shots. I had thought about selling the lenses but at the going rate you can't expect much. Now though, I have two valuable lenses that I am still able to use.

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?

If you're talking about the Nikon Normal AF Nikkor 50mm f/1.8D Autofocus Lens, then this filter kit would work for you because that lens has a 52 mm thread. By the way, it's a great kit at a great price.

Check the section below the lens listing that lists the various adapters available. You should be able to pin down the correct adapter for the 5100. Be aware that you will only have manual control over the lens...no auto modes.

you likely have to use the manual focus ring on the lens itself. This adaptor doesn't allow for auto-focus capability.

Hello - I bought this adapter thinking it would fit those lenses - and it didn't. I have both the 50mm f/1.8 and the 28 mm f/2.8 - both didn't fit b/c there's a metal stub at the bottom that does not allow it to mount on the adapter. The only lens I had that fit was the 75-150mm lens.I wouldn't buy it.
