I have just received a new Silvestri 6x Tilting loupe. Having looked around for a good loupe for some time and tried out quite a few as well, I must say this is truly a great loupe.
I've tried it out with my lenses and it's brillant (excuse the pun), a real innovative design. It works wonderfully well with the 65 mm & 110 mm, and allows easy focusing right into the darkened corners and the image looks bright, contrasty and sharp. I like the 6x magnification and it works beautifully with the Ebony fresnel GG. The tilting base allows you to tilt up to 45? if needed and the design allows the base to be comfortably placed exactly in the corner of the GG.
There is also another 'fixed' ring which can be screwed in, to replace the tilting base, so you can use it like a standard loupe if required. It is very l ight (80 grams), well made and well designed. It also has a diopter correction of +3/-1. I suffer from astigmatisim and focusing can sometimes be difficult, but I find focusing with this loupe a breeze.
It is well worth the US$60 I paid and I much prefer it to other loupes I have tried.
I have no connection to Sr. Silvestri, but when one finds a excellent product like this, I think it needs to be promoted. I hope anyone looking for loupe wil l give it a try, particularly if you use wide angle lenses. I'd thoroughy recommend this loupe.
