This ND filter was developed specifically for the iPhone. This should be taken into account, otherwise the verdict will probably not be so favorable. The special thing about it is that this ND filter with its filter ring completely encloses the camera module of the newer iPhones. The actual filter then lies directly on the lenses and sits really well.

Unfortunately, this doesn't work with a cell phone case that has a camera protector. Then the camera module becomes too big and the filter no longer fits over it.

The whole thing is held in place with a fairly tight clamp, which of course then covers part of the display. But in my opinion that's not particularly important.

The filter can be adjusted from filter strength ND2 to ND400 by simply turning it. The whole thing is done with a quarter turn, so all levels are pretty close together, so you should turn slowly. There is a 10-level division on the ring, but it can still be adjusted continuously. The filter does not always have the same effect on all three lenses. With the ultra-wide angle of the iPhone 14pro, for example, you can get the filter ring in the picture with some settings. In some settings you notice a slightly stronger vignetting. You have to try it out a bit, but you can get the hang of it quickly.

Who needs something like that? Certainly no one who doesn't know straight away what an ND filter does. The product is aimed more at photographers who want to get even more out of the iPhone and, especially in bright light, still want to use long shutter speeds. To do this, you would have to delve a little deeper into the subject. There are numerous, very good YouTube videos on the subject...

I think it's really great that the filter holder or clamp with a 52mm thread can also accommodate other filters. A polarizing filter or graduated filter would be exciting here for different effects.

In any case, I am very happy with this ND filter, even if I probably won't use it that often. I tend to take the photos or videos that can be produced with it with a system camera. But if you're travelling light or want to experiment with iPhone photography, this is the right choice. The price is unbeatable for this great quality.

I didn’t like that you can’t connect a wireless microphone but everything else is fine

This Bluetooth module performs as well as a $200 one, with equivalent sound quality. It takes few seconds to connect, the mic quality is fantastic.

The Boya Omic Wireless Mic is an impressive and cost-effective option that continually improves over time, now featuring a convenient charging case and significant sound enhancements. Compatible with computers, Android/iOS devices, and more, it's perfect for content creation, live streaming, Vlog filming, and mobile journalism. With outstanding sound quality, adjustable noise reduction, and an impressive wireless range of up to 50 meters, it ensures clear audio and flexibility. The portable system also has built-in rechargeable battery with up to 5 hours of runtime, extendable to 20 hours with the charging case, which supports wireless charging for added convenience.

The endoscope is a super solution for the DIY sector. In the professional field you might get the replacement battery for this price. Here you get a function in the form of a useful view, e.g. into the engine compartment or into very crooked spaces, which no smartphone camera can match. This saves a lot of time because major dismantling work can be avoided. The picture is significantly better than expected and both photos and films can be made so that you get a good overview of the condition or function of the objects that are simply to be examined, repaired or adjusted. The lighting is excellent. With strong reflections, it is very good that the light can be dimmed. I fix the endoscope with a collet so that steady pictures can be taken. You should also pay attention to well-cleaned lenses.

Perfect for DIY enthusiasts - helps in various household situations.

Put the butter in the fish - A solid camera that will come in very handy for the DIY enthusiast. It comes in a sturdy pouch where it can be stored. Processing is very good. That means the buttons can be pressed, the display is a nice size, the case is stable, the cable (I'll call it that) is firm, but still quite flexible, so that you can work with it well. We used it to check our floor to see whether the empty pipe was still in place to insert the sensor for the underfloor heating before we laid the floor. That worked very well with it. It handled the slight arc well, didn't get stuck in the grooves and the illumination was excellent allowing you to really see the entire inner tube. I can absolutely recommend it from that point of view. It is certainly more for home use in terms of image quality and Co., but in my opinion you don't do much wrong with it.
