Both shots with this lens look to be at f/2.8 ?

Looks a lot more interesting than the 50mm FA 1.4
which is the most boring of the Pentax 50mm's
I sold mine because it was so dull

The 'A' series is much better f/1.7 or f/1.4

Why carry a load of primes about when one zoom will do the job

Post any Zoom images you want here.

These are the Pentax-F SMC 28-80mm f3.5-4.5 shots....
Note: SMC version of lens not the cheapo ones

All K-5 on two separate days...






















And one showing the Bokeh




Edit:: Whoops! The butterfly was taken with the
Pentax 55-300mm probably with 1.4x TC..... still a zoom

Lenses basically fall into two categories...

A): Usable

B): Unusable

Some lenses in category A: are exceptional, but not essential
and don't get used much because other lenses in the same category
do the job quicker, are easier to carry and are more versatile.

Some lenses in category B: get raved about, but aren't
actually much use, probably old and now worth more moneywise
than their performance would indicate.

When I compared the K35 f/3.5 against the DA 35mm f/2.4, I
couldn't see much difference although the DA can produce
CA and someone once posted some shots in a church showing
sort of ghost reflections.

One good thing about the K35 is that it's sharp from wide open
and doesn't really change much stopping down. The A50 f/2.8
Macro is similar.

Doesn't Windows set up a massive swap file (and use it) based on
the size of you ram anyway?

On XP (with 4GB) just to load a small 32k text file into
Notepad I have to wait ages for the system to dump everything
to the swapfile before it will fire up Notepad?

Windows 98SE used to run great with no swapfile.... you just
put instructions not to use one in system.ini

The light on 6,7 and 8 is superb, but all the pics
are very good.... nice colours!

A 12-28mm would fit in well with a SMC F 28-80mm 3.5-4.5
giving good coverage from 12-80mm with 2 lenses and
reasonable semi-macro at 80mm, beating off most primes
along the way

Edit:
On 2nd thoughts we already have the 12-24mm plus
24-90mm which covers the same range and has close
focusing on the 24-90mm so maybe we don't need
the 12-28mm after all.

Ifranview used to have a plug-in that inserted any Exif
data such as date/time as text on the image.

Send a notification to the Department of Notifications
telling them that you haven't noticed any of their notifications
lately and just in case it's an error on your part ask them
to notify you whenever they are about to send a you new notification

Also ask them if they have noticed that you haven't
noticed any of their recent notifications

I only used to photograph a very small portion of the note, but now
use postage stamps instead. Most editors such as PS and Corel won't
let you import a photo of a UK banknote.
I think Dollar Bills are OK and they can be bought off ebay.
Or old banknotes from former communist now European
countries.

Strange thing is ebay is full of photos of UK banknotes
just search for it

For testing lenses at about 1M we aren't recording
much fine detail anyway.

Irish postage stamps have a lot of detail and are cheap on ebay.
