The rattler does what I need it to do and far exceeded my expectations. It has night vision mode, thermal image mode, and full color mode (for daytime, of course). Very Clear image. Easily identified deer at 2-300 yards. No hogs on the first night out. Field of view seems great. Coming from night vision, this is way better. This is the best bang for you buck thermal on the market with the features.

Fits perfectly I've actually tried it with several lenses. Lenses with a simple PK mount also work well. In this case, make sure you set the aperture ring of this adapter to the narrowest and controlling aperture over the original aperture ring on the lens. The reason for this is that the original aperture ring allows you to choose half-stops. With this adapter you can set full stops. When used with a DA/D-FA adapter, the aperture is set using the adapter's aperture ring. It allows you to set full stops. Better than nothing and it spins smoothly, with light clicks. The construction is of high quality, the interior is matte and non-reflective and comes in a beautiful box. The E-mount portion snaps comfortably into place, no hassle there. The PK side is a little tight on certain lenses, but as a benefit it doesn't wobble at all. Recommended!

The action on the variable ring is great. Smooth, stiff enough to stay in place but not so stiff as to unthread or overtighten to the lens. The optical quality is good to great with minimal internal reflection. At 500m / F11 / 1/250 s it's TOO dark for anything but a completely full moon. I'll probably use it more for full snow imaging than the intended purpose of lunar photography but I'll definitely use it.

It's amazing that the quality was so good for this price. Full metal, lockable aperture ring and flat support on camera and lens bayonet. Functional test with a Lumix G3 and Olympus Om-D 10 successful. This adapter deserves full marks.

With this adapter I can use all my Nikkor or Nikon lenses on the Fujifilm E-X1. However, it is necessary to set the “Shoot without a lens” option in the menu, otherwise the shutter button will not click. The diaphragm is closed by the intuitive ring. I tried it with a G Sigma EX 1 lens; 4-5.6 with 10-20mm focal points (equivalent to 15-30mm of a full frame): The ring allows you to close the aperture while maintaining full aperture for manual focus, from 24cm to infinity. Of course, the Fuji ring works better for Leitz M lenses, since it is enough to set "adapter" and focal length and any distortions can be corrected. But it costs more than ten times as much. Focus is obviously done manually as with digital and analogue Leica Ms. The courier was unable to deliver on the scheduled day, claiming that "no one was there". Instead we were all there. Saturday to Monday. Then don't complain if Amazon will use drones.

Bought in 2023, after a long time I feel like giving a review because it is the best lens of my kit. It has been used on Canon APS-C and now full frame Sony and has allowed me to take great shots home. Since it's wide-angle (so with a wide hyperfocal) you don't have to spend money to buy the autofocus version and the focus ring allows you to set focus very precisely and fluidly, but I'm sure that You will keep it in an infinite position 90% of the time. The other ring of the cone port is very useful and well made, with clicks that are easy to "hear". The sharpness is great, it loses slightly in the corners in full frame, but still remains excellent. Vignetting isn't a problem at all and closing the aperture at f/4 isn't as noticeable. I didn't notice any discrepancies in any of the many recordings. The aperture of f2.8 allows this lens to be used even in low light conditions or for those who want to take their first steps in the world of astrophotography. The downsides are minor and negligible: the outward weight distribution, the fixed lens hood, and the aperture ring partially covered by the built-in flash. I think this is the first lens to buy for those who want to "ditch" the kit. You will always carry it with you.

This dual-lens camera takes clear, full color pictures and videos recordings during the day and night (H.264 4K 30fps videos with clear sound)! It automatically adjusts itself using its infrared sensors for different lighting conditions. The starlight night vision is quite impressive! You really can get full color images in low light and clear black and white images in total darkness.

It's easy to connect this camera to your mobile phone via WIFI (up tp 33 feet away). You can even change setting and make adjustments to the angle and position, view a live stream feed and even download the pictures and video from the SD card to your phone!

All in all this is a very good, feature-rich trail camera and I would definitely recommend it!

I use the filter both for filming with the DSLR, as well as for long-term exposure during the day with an open aperture, especially when filming, it is simply beautiful with an open aperture. The ring is easy to turn. However, sound should be recorded externally, because the ring clicks quietly in the intended positions. The packaging is ideal for transport and also withstands the attacks of my 1-year-old daughter. The picture quality looks great. In any case, I could not see any color casts or other disturbances. I am very satisfied with the ND filter.
