Going to go against the grain here, I have a couple of older Artemis scopes, they are very good, particularly at what they cost second hand.
Had a look at/through the optika range at Ivythorn, not the same quality in terms of contrast or image sharpness / clarity. They are a mid range scope and won’t challenge the higher end brands.
Also, the lack of uk importer is an issue if anything goes wrong. I bought an ex demo pair of LRF binoculars, there was a fibre in the right hand tube, on the edge of the sight picture but annoyingly there. Still under warranty so sent back to the shop, they had a nightmare getting hold of Meopta but managed to eventually and sent the bin’s back for repair. Fast forward 5 months and I am still without my binoculars, though hopefully they’ll be back next week!
The shop have been really good, meopta not so much!
