Just a FYI...

Powerzoom also works with the MZ-S film camera.

The Powerzoom feature thingie that doesn't work with the MZ-S is the preset/constant zoom function that Ron Boggs talked about.

I find Powerzoom is most useful with the FA*28-70's big brother, the FA*80-200. The short throw of the 28-70 means you can manually zoom just as easily. But with the 80-200 powerzoom is very, very handy.

That's cool, thanks for the info. I had the MZS before but didn't have power zoom lenses back then. Now I might get a MZS back soon, I'm sure I'd have some fun w/ the FA*2870 mounted

where is can find a good and detalied review about pentax Star 28-70 f2.8 ?


My good and not so detailed review is that the FA* 28-70/2.8 is a piece of shit and that you should avoid it like the ebola virus...

...and some thinks the DA* 16-50/2.8 have problems....

mechanical problems, as I recall. He got mad at it and dismantled it. Mine has been great for 12+ years of, at times, heavy use. And optically superb.

Cheers,

a question about 28-70mm star:
in the focus ring i see a "flower icon": it is similar to usual "macro" symbol

for example see here "flower macro symbol"
http://www.cnet.com.au/story_media/339285843/11-macro.jpg

now i ask you: but 28-70mm has macro function?

Not macro, but close focus. It states maximum magnification of .25x which is the same as 1:4. Minumum focus is 430mm which is quite close for a lens at the 70mm end. Most primes used to have a closest focus of *about* 10x it's focal length, so a 50mm lens would be a minimum of about 500mm, a 70mm would be about 700mm etc. If you look at the K Mount page and look at the lens'close focus you will see that this *mostly* applies there abouts. The FA50 has a close focus of 450mm, so it is close to the 500mm.

The flower image on the lens means close focus area of the focus range.

thanks for info

questions:

1 - can youi tell me in easy english what means "close focus" in the focus range?

2 - for a comparative, i see the tamron 28-75mm F/2.8 AF28-75mm F/2.8 XR Di LD Aspherical (IF); Tamron USA, Inc.

"Minimum Focus Distance 0.33m (13") (entire zoom range)
Macro Magnification Ratio 1:3.9 (at 75mm) "

canm you tell me what is the "close focus" for tamron 28-75mm F/2.8?

i read here
Optics4Birding.com Specifications
"Close focus is the distance away you can bring something into sharp focus. This will determine how useful your optics are while viewing different things at different distances. In general, a shorter distance is preferable and makes the optic more versatile to use for multiple purposes."

is this a good definition for "Close focus" ?
