Sigma really did turn things around and they should get credit for that. 
They went from having a poor reputation for quality control and optics 
in the 1980's - mid 1990's,  to being considered solid in both areas to 
being an innovator and leader in lens offerings.


There are a lot of their current lenses - especially macros - that I 
wish were available in K mount. But a lot of lenses from the mid 1990's 
and earlier have poor reputations.

I don't know real old sigma.  When I got back into photography they 
had some "decent optical quality for the price" lenses. These days 
they seem to be doing some very top end work.  Their 18-35/1.8 is 
groundbreaking, and supposedly very, very sharp. Their art series 
lenses have stellar reputations.  My two biggest complaints about a 
lot of their new lenses is that they aren't available in Pentax mount, 
and I couldn't afford them if they were.

Sure, the A* is built like a tank. But I'm not going to war with it.
With all the APO optics improvements I would think the A* (but for
collectors) would be a lot cheaper?

Dear Dan, Pentax lenses have always been technically very advanced - at least 
my first SLR bought pre owned in 1975 - a Spotmatic with a Takumar proved to be.

The reason I latched on to Pentax were the grand Lenses - after owning a 
Pentacon, Nikon, Kiev-19, Leica, Ricoh SLRs.

I was amazed at the 35 - 135 F3.5 "A" zoom lens. Sharp all the way through - 
remember that this is not a computer designed lens. And I picked one up in Mint 
condition from a Pop & Mom Store in the San Francisco Bay Area for $65 + Tax.

I have attached my first attempt at Water Drop Photography using this lens 
which also has Macro - see attached link.

Thanks for looking.
Bipin

Photography will stop time – for eternity.

The M/A* f4.0 300mm lenses are very compact.  Some of us value that.  In
fact the A* and F 1.7x AF adapter don't take up a lot more room in my
bag than does a cheap 500mm mirror lens.   Now the mirror is a lot
lighter but with the lens and adapter combination I get to have two
focal lengths, and though the lens can be a little soft wide open, I've
gotten a lot of good shots with it.  I also paid about 100 dollars less
than current asking prices apparently.

A lot of people, myself included, prefer OEM equipment on general
principals. If I didn't like Pentax glass, there isn't much reason to shoot
with Pentax bodies.
