Re: Leupold or Kowa
I recently did a TON of research trying to find out that very question before I bought one.
if you search around you will find some articals comapring most major brands. this is done by birdwatching professionals (appartently they spend a lot of money to view birds). it is not ONE person's opinion, it was done by a dozen people all rating over 20 scopes at the same time under same conditions. of course opinions varied which is they had so many to reach an accurate aggregate.
here is the short version:
for best quality, meaning most clear at highest magnification and bright, you have to go to the very top ends of these lines:
Optolyth 30-60x100 (have seen as low 2,700)
Leica Televid 25-50x82 APO (around 3,500)
Swarovski ATM 25-50x80 HD ( around 3,200)
Zeiss Diascope 20-75x85 (around 3,000)
Vortex Razor HD 20-60x85 (NOTE: this one is half the price of the others in this category!!! around 1,600)
(Note: though Optolyth was brightest people didn't favor it due to size and weight; many bird watchers are not strong people)
after that it is a step down to scopes like those below that are all priced from around 600 to 1200:
Olivon 23-68x90ED
Kowa
Pentax PF-80ED
Leupold
Baush & Lomb
Minox
Meopta
Nikon Fieldscope ED III
(note: most of the brands in the top list also have lower priced versions that make it in this category)
then you get the low budget scopes which is a flooded market, and most if not all are total CRAP. The best of them if that is all you can afford is the:
Bushnell Legend HD
Personally, if I had the money, I would buy the top Optolyth or Vortex Razor because I think they offer the best price for the highest quality.
I DON'T have the money, so I bought a Bushnell Elite 15-45x60 straight version at auction for $285
I chose it because it is a good scope to mount on the driver's window of a car and easy to pack, plus I got it dirt cheap.
But bear in mind that it is NOT a scope you want to use for very long range shooting - you need better magnification!! I wasn't concerned with that because I can attach my canon 5D with which I can magnify the scope highest setting x10 and then use my field monitor to double that!! Of course, this is only for bench shooting and that camera and monitor are $6,000 worth of equipment that most people don't have.
highest quality - at least $1600 retail
mid quality - around $900 retail
best lower quality - around $400 retail
scopes priced lower belong in a landfill!!
So there you have it. I just saved you about 30 hours of research, so you own me a latte
