The lens was mounted on the Sony ZV-10.
As an amateur, this lens allows me to take professional photos that surprised me.
The autofocus works flawlessly and very quietly.
The f/1.4 saves crop cameras in low light conditions, no more high ISO and grain in photos.
Very good sharpness, especially in the f/4 to f/8 range, the photos are crystal clear.

For those who are in a dilemma of which one to choose first from the Sigma trio, the 30mm is the best choice in my opinion, it didn't limit me anywhere (we're talking about portrait and portrait with a little landscape).

I would also like to add my experience.

Initially, when I had connected them to the Cosmote router, I also had constant disconnections and they even affected my wifi connection (excellent on wifi, etc., while the wired connection was fine).

For home cinema purposes, I had to purchase the Ubiquiti UAP-AC-LR access point and when I connected them to it (a total of 5 traps), I completely stopped having any issues. A year later, I didn't have a single disconnection, so I believe that MIMO technology in wifi plays a big role, as well as a good access point, in order to have good connectivity with all devices, especially if you have many devices at home.

In conclusion, in my case, the problems were solved when I upgraded the access point.

An excellent telescope, great detail on Saturn, Jupiter, and even Mars. In darker areas, of course, you can chase nebulae (a bit blurry and faint for this mirror diameter but impressive) and galaxies. The Moon, of course, will provide impressive images.

Recommended 10000% for a beginner's first telescope as it is easy to transport! It's better to have a small telescope that you will use rather than a large one that will collect dust in the closet.

It can accept many modifications and there are many discussions in various Greek and foreign forums!

A laser collimator is recommended for quick alignments before each use.

Personally, I combined it with a Baader Zoom Mark IV eyepiece and a 3x Barlow, and it's like having many, many eyepieces!

May you have clear skies!
