The Pentax HD PENTAX-DA 645 28-45mm F4.5 ED AW SR is an ultra-wide-angle zoom lens designed to optimize the optical performance of the Pentax 645Z, and usable on all Pentax medium-format digital SLR cameras.

Providing focal lengths from 22mm to 35.5mm in the 35mm format, this is exclusively designed for digital imaging. Its image circle is optimized for an image sensor of the Pentax 645Z medium-format digital SLR camera, and a number of Pentax-developed technologies including advanced lens coatings are incorporated, to deliver super-high-resolution images made possible only by medium-format digital SLR cameras.

Thanks to its dustproof, weather-resistant construction, this lens also offers outstanding reliability and durability even under demanding shooting conditions, allowing the photographer to capture various outdoor images, such as sweeping landscapes, without worries.

Selling due to having to reduce the collection of lenses I have, its had very little use and is in superb, almost as new condition with all literature, boxed and an un-used Pentax soft case as original.

Looking for £3300, I will consider offers very close to this, that gives you a saving on the new price of £700 ( SRS - £3999 ) Bank Transfer preferred or happy to meet for inspection and cash on delivery, UK mainland only. Insured 48hr signed for Royal Mail postage is £200, which I'm happy to share if this is the preferred option.

Images as below of the Lens and some samples in use.

You only need to install the last one, it will include all previous updates

The grass isn't always necessarily greener on the other side,

There's always some sort of short-coming which ever brand opted for, 2 good friends recently, one has converted from Canon cos of the better ( quality ) feel of Pentax K3 in this case, the better low light performance and the easier menu options than what he was using, the other commented my images held better detail than his Nikon and the shutter ( K1 ) was soooooo much quieter than his when we were shooting some wildlife.

Hi Mel,

No problem, pleased its either resolved itself of you've found the issue, make sure the battery is fully charged before starting the firmware update

Ok, try removing the lens,

Wipe the contacts on both the lens and the mount to make sure they are dry with a cloth, then put the lens back checking it clicks fully home

Check you are in the correct mode, does it work properly in say fully manual ( M ) ? can u adjust the shutter speed and aperture ?

Is there a card in the camera, or is the card door open, this has caught me out on one occasion

Other than that, is the camera working, i.e

is it auto focussing ok ?

does it take an image and is it correctly exposed ?

Try taking the battery out for 30 seconds and then replace

Me to, an excellent shot 😊

Superbly shot Alan, #5 for me

No problem Barrie, pleased it worked 4 u as well
