Hello all,

Thanks for your response!

Apparently the Jen increased, the cheapest new Pentax 45/4.0with full warrantee will cost about 750 dollars

(in the Netherlands). Tomorrow I will meet someone who has a used one for sale, which is in good condition for about 550 dollars. So I will check this out! Yippee!

Kind regards Gert Jan.

Hello,

I enjoined reading the posters a lot

I� m considering to buy a 45/4 wide angle for my P 6*7 (like a 24 ~

21 mm for 35mm)

The experience with a 20 mm for 35mm system showed me a lot of

distortion due to the design of the lens (Cosina) straight lines

appear like the letter W and also a lot of light fall of to the

corners

So far I have good experiences with the 75/4.5 and the 55/3.5 luckily

the 55 came with 3 filters and lens hood

My questions are:

1) how is the performance of this lens at wide open and at 8

2) Are there different versions of the 45 mm like the 55 which has a

3.5 and a 4 opening and how to recognize those.

3) what is a reasonable price

Thanks in advance Gert Jan

Hello Colin

I use the M645J for 10 years now with out any problem. The M645 does not have MLU and a second release button and only 1/500 as fastest speed and yes you can make double expos. If you insist on working handheld and with a prism you better get a Grip L so you can release with your left hand.
