Distinguished by its refined physical construction, the 11mm f/4 Blackstone Lens from Irix is an ultra-wide prime designed for Nikon F-mount DSLRs. As a rectilinear lens, the advanced optical layout makes use of aspherical, extra-low dispersion, and high-refractive index elements to control distortion and aberrations for accurate, and sharp rendering with a high degree of clarity and color accuracy. Additionally, a Neutrino coating has also been applied to the lens to control flare and ghosting for improved contrast when working in strong lighting conditions.
Beyond its optical assets, this 11mm f/4 lens also sports a manual focus design for fine-tuned control, and incorporates a unique positive focus lock to secure the focusing position at any point for consistent, repeatable shooting. As the Blackstone version of this focal length, this lens is also distinguished by an aluminum and magnesium alloy exterior, engraved lens markings with fluorescent UV paint for high visibility, and extensive weather-sealing about the lens to permit working in harsh environments.
- The Blackstone version of the 11mm f/4 lens features a durable aluminum and magnesium alloy housing and weather-resistant exterior along with inner seals, and an extra seal at the front element, to protect against dust and moisture intrusion. The metal exterior also distinguishes itself with an anti-scratch finish, and sports engraved focus distance and depth of field scales with fluorescent UV paint for high visibility when working in low-light conditions.
- Ultra wide-angle prime designed for FX-format Nikon F-mount DSLRs, this lens can also be used on DX models where it provides a 16.5mm equivalent focal length.
- Three aspherical, four high-refractive index, and two extra-low dispersion elements are featured within the optical design to limit both spherical and chromatic aberrations, as well as color fringing and distortion, for improved clarity, sharpness, and even illumination.
- A Neutrino coating has been applied to limit lens flare and ghosting for improved contrast and color fidelity.
- Manual focus designed is benefitted by a positive focus lock mechanism to secure your focus position at any point to limit unwanted shifting of focus.
- A hard click stop indicates the infinity position on the focus ring for easy use in low-visibility conditions.
- Large depth of field scale benefits using hyperfocal and pre-focus techniques.
- Built-in petal-shaped lens hood blocks stray light in order to reduce lens flare, and also protects the front element of the lens.
- Rear of the lens accepts 30 x 30mm cut gel filters.
- Rounded nine-blade diaphragm contributes to smooth bokeh.

Low/mid-tier toy at a high price point
Color: YELLOW
I have two pitbulls and they LOVE their babies! Sadly, one of them likes to tear their babies apart when he gets anxious, so it was time to look for some new ones. They seem to favor any stuffed animal can be "nommed" on (suckled), so when I came across this duck rope toy, I thought I'd give it a try!
The toy arrived quickly, did not have any visible defects, and looked exactly as it does in the listing photos. It has a body filled with stuffing, crinkly arms, and a rope neck. There is one squeaker in the main body section. The minute the dogs saw me unpack the duck, they were at my feet and staring at me like "hand over the baby, woman." So, I did.....
And they hated it :(
For some reason, my dogs have totally rejected this toy... All they do is sniff it? They typically LOVE rope toys or anything that is elongated and allows them to play tug-o-war. So, I am not sure what the deal is with this duck. *shrug*
Currently, this stuffed duck rope toy is listed for $10.49 on sale, down from the regular price of $14.99. I consider this toy to be low end to mid tier at best. It's something you would expect to find at your local discount/dollar store. Based on the lower quality, I think the current price is higher than I would be willing to pay for this toy. While the toy is exactly as depicted in the listing photos, it is nothing special and definitely is NOT "indestructible."

Durable and my pup loves it
Color: YELLOW, Color: YELLOW
My pup loves squeaky toys. The problem is she also likes to tear up the toy to get the squeaky out. Finding a toy that she enjoys and it have the durability to stand up to her is a challenge.
I decided to give the CJZJPV Plush goose a try and I’m glad I did.
She absolutely loves the toy and it has stood up to her chewing and shaking.
The thing I notice about many dog toys is there always seems to be a bad seam or weak spot in the toy. My pup will find this imperfection and go ahead to dismantle the toy.
The seams on the CJZJPV are done well and there are no protruding eyes or flaw for her to get her teeth into.
This is a good, durable dog toy.

A huge hit for the whole pack
Color: GREEN
Finding a toy that appeals to multiple dogs with different play styles is tough, but this interactive green goose is an absolute home run. The combination of the crinkle wings and the squeaker keeps them entertained and busy way longer than a standard plush toy.
Despite the daily thrashing, tugging, and chewing, the durability has been incredibly impressive. It’s the perfect size for larger breeds to grip, yet lightweight enough for smaller dogs to carry around by the neck.

Great toy that's a real hit so far!
Color: YELLOW
This squeaky goose has been a total hit and, more importantly, it actually passed the "German Shepherd test." It is always a gamble with plush toys and large breeds, but this one has stayed completely intact after several play sessions. Even with all the shaking and carrying around, the seams are holding up perfectly and the squeaker is still going strong. The combination of the squeak and the crinkle wings keeps things interesting, and the material feels much more durable than your average stuffed toy. If you have a powerful chewer who still loves a soft toy to carry around, this is a great, resilient option that won't fall apart immediately.
