Review: Great set of binoculars at a very good price! - I’m really impressed with these Cason binoculars. The image is clear and sharp, and they feel sturdy in hand. Great value for the price and perfect for travel, birdwatching, or outdoor adventures. 👍🔭
Review: Good Binocular and buy at this price point - This review is for Cason 10x50. -- Overall 3.5/5 I was looking for low cost binoculars as my use is very limited. Already had a celestron g2 10x50 for 12 yrs and it finally got bad(fungus) so had to get something quick for my trip. So my reivew will have comparision to celestron g2. Below getting this I tried Sounce 10x50 bino 2 times and each time it came broken..so first is avoid that if you can. Now to Cason 10x50... its a decent binocular at this price point. Build Quality: build is good and feels sturdy. Packaging was fine as well. Rubber coating overall is okay and doesn't feel premium but at this price point its best. Lens come coated and its easily visible. If its FMC or multi coated and BAK4 or BAK 7, have to go what package says. There isn't way to verify that unless we compare with high range binos like nikon. Eye Piece : Eye piece is bigger and I thought it will be good..on the contary with this bino it requires you to look through dead center of eye piece to get clear image otherwise you start seeing black areas. So it more of adjusting how you view. I find it best with little distance between eyes and lens. It takes away the immersive view but you dont have to adjust continously. Cason advertises of folding rubber cups for people with spec. This doesn't work as the cups are of less height and does not fold in any way. So this function does not work. With my old binos I never had this problem. Image Quality: Image is very clear at center and its expected. I did see blurring at edges and chomatic aberration as well. So still doubting the overall coating and prism quality. However, its not a major concern and center view is excellent. We get what we pay. I would rate image qualilty slightly lower to celestron g2 (bak7/coated ) as there is no blur and minimal chomatic aberration at edges in that. Focusing and diopter are fine as well. Its easy and simple to use. Overall at this price point we can't ask more it works!!. So there are pluses and minus points. I think my old bino was anyday better, however I will keep this as my usage is very limited, I needed it immeidately and low cost. I just hope Cason can see this and improve more. Would like our indian brands to become world class very fast.
