If you’re like me, though, such a lens is only really a useful option if the optics are good as well. The 46mm filter size is shared by a lot of similarly sized lenses in the system too (also unlike the 9-18), they got a lot right with this one.

I know it would not be as small if it was a constant f4 but for me i would be happy for the slight increase in size for the slight increase in speed. Sure, some of their effectiveness is due to modern sensors, but advances in lens technology make modern glass astonishingly capable.As a parent, you hope your child is extremely successful and likely become the next Gates, Zuckerberg, or Meg Whitman. Thanks to its compact, high-quality design, this lens is the perfect companion to bring on your travels. With care, the stabilisation system allows sharp shots to be taken just over half the time at 1/15sec at 100mm, which is roughly three stops slower than the usual rule of thumb would allow. If one is looking for a really small, sharp, telephoto lens, for a modest investment, this is a good option. This new lens, which gives the same field of view as the classic 70-200mm telephoto zooms on 35mm cameras, is exceptionally small, making it an ideal choice for inclusion in super-lightweight travel kits.

As focusing is performed internally the 46mm filter thread does not rotate, which makes this lens ideal for use with graduated and polarising filters. One thing we teach our students at Thinkster is that there are multiple ways to solve a math problem.Boasts a rugged, dust and splash-proof design and is even freeze-proof down to -10℃, to withstand professional use under harsh conditions. Small changes in focus are conducted extremely quickly, and there's very little noise when the lens focuses. Panasonic’s Nano Surface Coating technology has been applied to the lenses within the system to ensure images are consistently crystal clear – even when photographing light sources in low light environments.
