The Tamron C-Mount 4 to 12mm Varifocal Manual Iris Lens is a varifocal lens which features a 4 to 12mm adjustable focal length. Compatible with cameras using a 1/2" imager size and C-mount, the lens is designed to deliver high-quality imagery. With an aperture range of f/1.4 to close, the lens allows for clear images even in low light conditions. The lens surface is multi-coated for lessening ghosting and flare in backlit conditions and eliminates constructional problems such as lopsided blur and focal point image degradation. The integrated slip-mount mechanism allows you to fine-tune the position after mounting the camera to set the auto-iris meter to a proper position around the lens. With the lock for each control ring (zoom and focus), you can avoid setting displacement after installation.

Great fun for our dogs!
Style: Original
My dogs can’t get enough of this very noisy ball. We have one outside and one in their playroom. It is very noisy. It is very hard. So, I’d say a room with fine furniture is not the place for it. Ours bang it around pretty good. Our boxer did split one, biting it. But, she’s a serious chewer! Our other dog carries it around sometimes but hasn’t been able to damage it yet. So, I’d say for most chewers it’s going to last a long time. It’s a great toy but in most households I’d say basement or outside. Again, it’s hard and did ding a few baseboards.

Superb!
Style: Original
My dog absolutely loves this ball. It's too big for him to fit all the way in his mouth, so it's held up pretty well and still makes the sounds.

Durable, Rugged, Dog Approved Fun!!
Style: Original, Style: Original
This thing is durable and worth every penny! I bought this over 5 years ago for my rescue and he STILL loves it. He plays with it near daily and it's got a LOT of love-work scrapes, scratches, and scuffs. But it still works perfectly!! Because he's on the medium side, he can't quite bite down on it. Not sure how it'd hold up to heavy chewers with larger mouths. But he can play with this solo for ages and has SO MUCH fun. We love to listen to his "conversations" as he gets into it with this ball. It's been a winner since the day we took it out of the box. It's also the longest lasting toy we still have! Everything else either wore out, was destroyed, or broke. This battery-free ball has made the cut for us.

Lasted a day for my dog
Style: Original, Style: Original
My dog absolutely loved this toy, but sadly it didn’t even last a full day 😩 I’m not sure if that’s because I have a Rottweiler/Lab mix with the jaw strength of a tiny excavator, or if the durability just isn’t great. Within a few hours, he had already torn right through it 🥲 That said, the sound it makes had us cracking up and definitely kept my dog entertained and intrigued while it lasted!
