Returning to the OP: The question was, what
kit.zoom replacement (
not a prime) is good for low light and has "great depth of field"? The latter is tricky -- what's wanted, thick DOF, or great DOF control (thin DOF)? Without venturing into Circles Of Confusion, we can say that:
* Longer faster lenses have thinner DOF and thus more DOF control.
* Wider lenses of any speed (aperture) have thicker DOF and may be quite suitable for low light, as shown by the 1/FL motion-stopping comparison.
I think most of us agree that the Tamron 17-50/2.8 is a great candidate. It's in the same focal range as the DA18-55, is much faster overall, offers better optics and adequate DOF control, and doesn't cost a mint. I could suggest all sorts of primes, and zooms in other ranges, but those don't address the question. If
primes had been asked about, I wouldn't hesitate recommending some 24/2 or 30/1.4.
Originally posted by dannydza O.k guys thanks for the replies, Im now more confused!!! lol.. I still might think about the 50mm 1.4, But I'm not 100%, why does there have to be such a selection of lenses! I just want to make the correct decision with my next purchase.
So many choices! Not quite as bad as wandering down the breakfast cereal aisle at any supermarkup, but still daunting! Learning the differences between lenses takes time. But, some points:
* Is no perfect lens. Each lens is a different tool for different tasks.
* Even a perfect lens for somebody else might not be perfect for you.
* Good old manual-focus lenses can cost a fraction of new AF lenses.
* We're not married to new lenses. If it doesn't suit you, send it back.
In other words, don't sweat it. Buy a lens that seems appropriate. If it works for you, great! If not, be sure the seller has a no-questions return+refund policy.
