Why not get rid of these problem cameras (*ist DL, *ist DL2, K100D) and get something else? I am not sure what capacitor to use or where to solder it. I have seen no clear pictures or instructions of the process to apply this fix. For all I can see it is one costly paperweight.
I'm considering another one of Pentax DSLRs, but do any of them have this or a similar problem? In fact, I just cannot help but wonder, how long can we expect any of these DSLRs, from any manufacturer last? I am tempted to think for one of these electronic wonders to last a decade would be a long time. In contrast my old Pentax ME Super has lasted me for nearly 30 years and four CLAs (Cleaned,Lubed and Adjusted). As a film camera it was not top of the line, but was well made and lasted a long time. It was even worth getting fixed. Perhaps I should just go back to a simple and rugged old film camera.
I need more information before spending my money on another DSLR. I just hope someone on this forum can recommend an answer to these questions.
