I checked out the 60mm and the 70mm , They were good, then i compared the 884 to the other big names, Through my eyes the kowa was the glass for me, i got tired of the ok glass that i had for years, yes the 884 is big and heavy but i pack it anyway, why carry a light weight that sucks, the extra weight is less than 2 bottles of water, all the reviews i read put the 884 on top , shop around and you can find one for about $2,700, buy once and forget about it..
