I have 4 lens to go with my ZX-5n:
- Pentax A 28mm f2.8 (which I may sell?)
- Pentax FA 28-80mm f3.5-5.6
- Pentax FA 80-320mm f4.5-5.6
- Vivitar Series 1 AF 19-35mm f3.5-4.5
I'd like to add a lens that can support macro photography and have found the following
potential options in my price range:
- Pentax FA Macro 50mm f2.8
- Sigma Macro 50mm f2.8 EX AF
The minimum focus distance for the Pentax is 19.5cm/7.6 inches; the Sigma is
18.8cm/7.4 inches.
My questions to the group are:
1. Are there any other similar lenses I should consider?
2. Does anyone have either of these particular lens? If so, what do you think of it?
3. The Sigma lens is about $120/US less than the Pentax. Is there an advantage of the
Pentax over the Sigma that isn't readily apparent?
4. Would it be smarter - it is cheaper - to buy the Pentax FA 50mm f1.4? Minimum
focus on this lens is 45cm/1.5 feet. Could I use the faster lens for minimal macro
work (flowers, etc.) with close-up filter(s)? What would be the draw backs of this
approach?
I appreciate any and all assistance!
