EDIT: Ok, so maybe my original post was a bit over the top, let me redo my question:
I recently bought a very cheap loupe but I am not completely happy with the chromatic abbheration etc, and now I have a really hard time finding a proper good one, as the information I can find is very scarce and subjective, but I am looking for the following in the loupe:
Magnification: 10x to 20x. (Closer to 20x than 10x is preferred.)
Lens correcting: I would want something with as little distortion as possible, so at least a Triple lens.
Cost: Preferably closer to 50€ than 100€ but I will prioritize quality.
Focal Length: It does not matter but I have shaky hands and will likely want to rest the hand holding the coin on top of my head or the hand holding the loupe, though this is plainly a QoL thing and not at all required.
Viewing Angle: A little bit wider than standard is preferred, but again, quality is the priority.
Brand: This is probably where the easiest and most constructive advice can be given, as my biggest issue is in finding a brand that I can trust, as I have found multiple models that seem decent, but I know nothing and can find nothing conclusive on particular brands.
PS. A few brands so far have caught my attention:
1. KITE. (I have seen this brand being mentioned a few times.)
2. Opticron (Seen this mentioned once but is readily available.)
3. NIKON (Mentioned and also known, but rather expensive.)
4. Belomo (Heard mentioned and seems interesting, but seems sold out everywhere.)
5+. Eschenbach, Schweizer, Viewlux (First reaction would be that these three are just brands that rebrand imported stuff, but could be wrong.)
UPDATE:
Ended up ordering a KITE 10x Triplet and a KITE 20x Triplet, haha. If good, then Ill have a backup, if not…eh, Ill survive.
