First three rules of computing which applies equally to digital photography:-

Backup!..... BACKUP!!..... BACKUP!!!.....

The fact is that digital files by nature of what they are and the current technology that stores them is inherently unsecure.

For peace of mind, multiple backups are necessary.... and even then.... there are no guarantees.

In spite of all our modern technology, a printed copy of a photo is still hard to beat. Whilst on the face of it (no pun intended)printed photo's are still fragile, paper from biblical times is still around and readable. I wonder if present day digital information stored on today's technology will be accessible two thousand plus years from now!

I don't mean to make light of your loss and you have my greatest sympathy, but there are lessons to be learned from this.

On a final note and possibly a ray of hope, computer failure does not always equate to a total loss of digital information on your hard drive. There is possibly a good chance of the information being recovered. If it's not within your capabilities, do you have or know of any tech savvy friends, colleagues or acquaintances who might assist you. There are companies who can undertake such recovery for you, however, their charges usually border on the realms of highway robbery and blackmail!

Good luck anyway.

Ffordes have a couple for sale listed as mint. https://www.ffordes.com/p/SH-18-003427/lenses-pentax-af/16-50mm-f28-a-da-sdm

I think those results are truly fantastic and a credit to your endeavours Peter. Congratulations to you.

Who would have thought?

I do hope you are enjoying yourself.

Best regards, D.

It's a fantastic image whatever it was shot on. Beautiful tones and full of atmosphere.

I agree. However, I don't think this is anything sinister on their part. Lack of attention to detail maybe. The green band though on the photo of the lens itself does clearly indicate it to be a DA lens and if that wasn't clear, the additional link that I provided doesn't leave anything to chance.

I think anyway that the vast, vast majority of Pentax users are an astute bunch who would be unlikely to purchase this lens thinking it was full frame.

If there was any danger of this happening, your timely intervention highlighting the sellers omission should save their bacon so to speak.

Have a good weekend.

Caveat... manual focus only!!!...

67 year old film that probably doubted ever seeing the light of day is now winging its way to you.

Curious to see how it shapes up!

Delighted that you have picked up the gauntlet Peter.
Will post on Monday.

Best regards.

Please let me challenge you Peter.

I have in front of me an unused 36 exposure boxed cassette of Ilford 35mm FP3 film dated 1952.
I would love someone to be able to use, develop and hopefully produce some nice prints from this film.
If you think it is within your capability to do this, please message me with your address and I will gladly post it to you free of charge to experiment with.

I sold off all my film processing and printing equipment a few years ago so I'm unable to make use of it myself but more than happy for some one else to try their hand and expertise with it.
