Hope someone can help me out on this one. I'm looking at buying a macro lens and in particular been looking at the Fantasea range. Here is where I get confused: what is the difference between a SharpEye lens and the UCL range?
Here are the specs on each:
UCL-05LF +6 Macro Lens
•Description: +6 diopter close-up lens
•Bezel Material: Hard anodized aluminum with black hard coating
•Lens Construction: 3 groups and 4 elements
•Lens Coating: AR multi layer coating
•Threads: 67mm (front and rear)
•Dimensions: 74 x 41.1 mm / 2.9 x 1.6 inch
•Weight: 254 g / 9 oz
SharpEye M67 +8
•Lens Construction: 2 groups, 2 elements
•Focal Length/Diopter: 125mm / +8 (Underwater)
•Features a 67mm thread mount
•Lens Coating: multi AR coating + water repellent coating (outer surface)
•Barrel Material: Aluminum with black anodize
•Dimensions: Ø 72mm x 22.5mm (D)
All I can make out is the UCL is longer and heavier, but what get me is the construction specs. What does 2 groups, 2 elements vs. 3 groups, 4 elements mean to me as the user? Is the latter a better makeup of the lens though the SharpEye has higher magnification properties?
Any clarification will be appreciated.
