Originally posted by dgaies Agreed. My first lens kit (which went with a K10D) was the 18-55, 50-200, FA35/2 and FA50/1.4. Those four lenses cost me about $800 and where the only lenses I owned for the first three years I shot. It served me pretty well as a kit and there really weren't many times where I felt I needed anything else. Then in year four I discovered Pentax Forums (and LBA) and let's just say that 4 lenses turned into 40 and my $800 budget turned into a much higher number
My first kit was somewhat similar: 18-55, 50-200, A 50/1.7 and A 28/2.8 . And I still have those lenses, except for replacing the 50-200 with a Sigma 18-200 (because when I want a long zoom I may also want to take a wide shot without having time to change lenses; I am mostly a prime shooter, and the zoom is special purpose/backup). But those are not the lenses I would recommend for someone starting out knowing what I know. :-) These days, if I were building a $1000 kit from scratch, I would take just one zoom and some autofocus primes. Just because.
For the zooms, I would choose to spend $250-$500 on an all-purpose zoom -- either an 18-135, 18-200, or 18-250. Selection would depend on whether the body was WR, how important the shooter feels the long end of the range to be, whether size matters, etc.
For the primes, I would spend $500-$750 on two of the following:
15mm Limited ($500)
21mm Limited ($500)
24mm Sigma ($500 if /1.8 or $200 for used /2.8)
28mm/2.8 ($250 used)
35mm/2.4 ($200)
40mm Limited ($400)
and then something for Macro:
100/2.8 AF ($500)
or an old 100mm MF Macro, if autofocus is not that important ($100).
So in this case the money runs out after about three lenses, e.g.:
18-135 + 15mm Limited + 35/2.4 ($1200)
18-200 + 28/2.8 + 100/2.8 AF ($1000)
18-250 + 24mm Sigma/1.8 + 100mm MF ($1100)
I don't think there is a "right answer" to this, except to spend a little more on lenses. I have an easier time coming up with a "best" $1750:
18 -135 + 15mm Limited + 35mm/2.4 + 100/2.8.
That, or a variant on it for individual preferences, should please any mostly-prime AF Pentax shooter.
And yes, I am leaving the 50mm focal length empty on this list, because I just don't find it that useful. You could add an A/1.7 to one of these lists for $75 if you like, and call it covered . . .
