This is a somewhat smaller, lighter and more powerful version of the celebrated 31 Nagler Type 5. Why? Because customers such as Tom Dietz, from the Smithsonian, are pests! :-) It weighs about 1.6 lbs and has a field stop diameter of 35mm. It is parfocal with the 17mm Nagler Type 4, making it a nice match in size, weight and convenience. Delos' 72° field produces incredible sharpness from edge to edge--Perfect for all objects.  perfect for glasses wearers and non-glasses wearers because of an innovative eyecup design. An ultrawide 82° field and argon-purged waterproof construction w/superb coatings all combine to make these the "Everyman's Series", useful on every type of object. 24mm FL
