I don't have much experience with scopes to compare to, but I didn't want to waste my money on something I would upgrade in a few years. I can't compare this to the 800 models, but I know that this size and weight would make this worth the buy for most people! Recently, I encountered someone who had a bird in their scope that was a rare bird and I digiscoped it to document the sighting, because I didn't want to bother finding it in the scope myself. The picture was such poor quality compared to what I've been taking with my Kowa TSN 553. I'd recommend this to anyone.

Prominar - The Pinnacle Of Optical Excellence
Only the finest optics deserve the accolade of the PROMINAR title. Optics that utilize Kowa's unique benchmark feature - fluorite crystal, delivering simply the best optical performance available today.
Incredible Clarity
At the heart of the TSN-550 PROMINAR series spotting scope beats a fluorite crystal objective lens. This natural mineral has an outstanding feature of very low dispersion that cannot be found in optical glass. This characteristic enables Kowa to eliminate color blur almost completely and dramatically increase resolution and contrast. Fluorite crystal is a unique feature of Kowa spotting scopes and is a testament to decades of Kowa optical developments.
Fluorite Crystal - The Ultimate Viewing Experience
A mysterious stone called fluorite, emits light like a firefly when it is heated or exposed to ultraviolet radiation. Fluorite has an outstanding feature of very low dispersion that cannot be found in optical glass, This characteristic enables Kowa to eliminate color blur almost completely and dramatically increase resolution and contrast. Fluorite is considerably more difficult to handle than optical glass, it requires highly advanced processing technology. Kowa put forth extra care, time and technique to produce the ultimate viewing experience with a pure fluorite crystal lens. It's what makes Kowa unique.
The Difference is Clear
The optimum optical material to minimize chromatic aberration is fluorite crystal. Fluorite crystal with extremely low dispersion characteristics is used for the convex lens of the Kowa TSN-550 PROMINAR models.
Perfection in the Palm of Your Hand
Kowa's dream was to create an ultra-portable spotting scope delivering the highest levels of optical performance. This vision has been realized in the TSN-550 PROMINAR.
More than Just an Optic - it Fits Your Way Life
The TSN-550 PROMINAR represents a way of thinking, a way of life. An optic that enhances every moment you use it. It's unique. A spotting scope this compact creates new opportunities. Wherever your journey takes you, the Kowa TSN-550 is the perfect travel companion.
Reliability Guaranteed
A lightweight yet durable, fully waterproof and nitrogen filled chassis ensures performance in the toughest of environments.
The Legacy Continues
Not only does the TSN-550 PROMINAR adopt the unique styling of it's larger predecessor, it also inherits what makes the TSN-880 still unrivalled to this day - decades of Kowa optical development. The result? A new benchmark optic in the compact spotting scope market.
