I use both large format and digital formats. I find the quality very good and well presented in a case. I will inform my colleagues about my results.

Exactly what I need for a full format camera and max medium telephoto

I've been shooting professionally in NYC medium format photography for 20 years. I'm used to HEAVY quality tripods. I no longer need a HEAVY tripod! I am retired and now shoot with a DSLR, Cannon G7x MII or my phone. I'm a big fan of the ball head & the included quick release mount! The carrying case is great for protecting and storing the tripod. This is awesome for traveling or hiking to take a selfie or time lapse! It's packed with professional features!

Great entry-level scope. Great performance, easy to use, the image quality is pretty good, and the instrument can be very helpful for students.

This is a great night vision glass of the entry -level class

These are great entry-level night vision binoculars

After initial difficulties, we are now satisfied. Affordable entry-level device.

Filter and variable entry level, really low cost. Good for learning how to use it.
Colors shift slightly to yellow.
The dial spins smoothly, but it does not have end stops, so it spins at infinity, which is annoying, as you need to have visual feedback on the dial to check the massive position.
The K&F Concept filter is fairly smooth, except at the point near the maximum, where it starts to vignette a bit. Beyond the maximum the X appears, and it is therefore unusable.
In any case a good expense to practice with ND filters without spending a fortune.
