Changing seals is incredibly easy, well worth doing yourself.
What seems 'incredibly easy' to some, can be nigh on impossible to others.

Yes it can be a DIY job if you can get a pre-cut seal set for the A1.

I've successfully put new seals on an ME and a Super-A, but only because I was able to find pre-cut seals.

I think the most likely cause is degraded light seals. I'd contact Harrow Technical or Asahi Photo for a service, but you might not consider the expense is worth it.

Unless you are really ham-fisted, I doubt you'd get the film loading wrong

You haven't said which film camera, but it looks to me as if light is leaking in somewhere.

If it's an older MX, ME, Super-A etc, the seals rot down to a black goo and need to be replaced.

When was the last time you used the camera, and were the prints OK?

Is it possible that you didn't close the back properly?

. . . I'm really suprised that hardly anyone has pointed to the DA-35mm 2.8 Ltd macro'...
That's perhaps because many people, except those who have this lens, consider it of limited use for macro work.

I'm not denying it's a very good lens, but whilst most macro newbies start off with flower and other static subjects, it's not long before they notice that flowers attract small bugs, and the 35mm is too wide IMHO.

I think the focal length favoured by the majority of macro shooters is around 100mm.

Your location is too vague for anybody to be able to offer help. If you would narrow it down to a county at least, somebody might offer to clean it for you. It is certainly not worth wasting £35 to have it cleaned 'professionally'.

Get yourself some PecPads and Eclipse fluid and do it yourself.

One common mistake is to leave the red-eye reduction setting on giving the impression that a pre-flash is occurring, when in fact, it isn't, or may not be.

TTL flash employs feedback from a sensor inside the mirror box which measures the light reflected from the film/sensor surface. Could your *istD TTL sensor have some foreign body inside it perhaps?

Can you beg, steal, or borrow an older Pentax TTL flash and try that, say an AF280T or similar?

ANother good option, and preferable to a £23.00 set of 'close-up lenses', is a Raynox macro adapter. Their DCR-250 product is exceptionally good and you should get change out of £50.00

If you have anything close to a 50mm prime, a reversing adapter might suit your budget.

In my opinion, there is no real substitute for a dedicated macro lens.

Is there a big difference between 1:1 and 1:2?
I know it's 1/2 the magnification but what do most people use etc.
1:1 and greater here.

All of my macro lenses can produce 1:1 magnification. With tubs and/or bellows, greater magnifications are possible with trade-offs.

Fortunately I anticipated every eventuality and spread my shots across 3 memory cards ( even though I have never had an SD card fail before ) so the shots lost are only about 30% of what I did.
I'm not sure that the card slot in the camera is robust enough to handle so many card changes.

Much better to have two identical, or near identical, bodies and use them both on a shoot.

Having a spare body in case one breaks is OK, as long as you know that the one you are using has broken in some way.
