2002-01-27 Thread Ayash Kanto Mukherjee

Hallo John!

Thanks for your views.
I still have a small question, if you don't mind. The one with IF has 15
elements in 12 groups while the one with power zoom has 13 elements with
11 groups. Don't you think that the IF one could have closer optical
performance to its power zoom counterpart if not equal?
Have you compared the two lenses side by side? Just inquisitive.
I apologise beforehand if I am disturbing you.

With regards,
Ayash.

No question, the old power zoom is a much better lens.  
One of the best in its class.

FA 28-105 mm f/4-5.6

2002-01-27 Thread Ayash Kanto Mukherjee

Hallo all!

According to Boz's K-mount page, PENTAX produces two FA lenses in the
range 28-105mm f/4-5.6

One has power zoom option and the other one has IF (Internal Focussing).
Boz has also stated that the one with IF is possibly fabricated by Tamron
wth genuine PENTAX electroncs and SMC coating.

How does the optical performance of the one with IF compares with the one
with Power Zoom?

Inquisitive.
