Wow great lenses!

Pros:

• Has the largest aperture the lens has to offer with a F1,4
• 105mm it is also good for macro and telephoto
• The lens is also water proof and dust proof

Cons:

• It has a fixed zooming lens, with 105mm lens you cannot zoom in & out with this kind of lens.
• Very Expensive with a price of almost 3 years of my salary!

Keep up the Good work!
