Originally posted by PentaxPoke Careful there jeff. I know well the Lensrental site you are referring to. Just under the information you posted above, is this statement from lensrental:
"Fanboys love to misuse the list above, and one of the common things I’ve seen is,“Brand X has the most (or least) lenses on Lensrentals’ high repair rate list.” Lets keep it in perspective. There were 45 Canon, 36 Nikon, 17 Sigma, 6 Tamron, and 3 Tokina lenses eligible to make the list. The final makeup was 7 Canon, 6 Nikon, 3 Sigma, and 1 Tamron. Every brand seems to have some troubled and some trouble free lenses."
I am not accusing you of being a "fanboy" but it sure would be nice if we didn't divert focus away from the purpose of this thread which is a discussion of 16-50 problems. Also, I don't think that we should take comfort in data from one of the largest lens rental companies, that doesn't even see the Pentax market as being large enough to carry any Pentax lenses.
There biggest complaint is saying one brand is better then another based on this data. Singling out one lens and highlighting it's failure rate is perfectly valid..
It is a fact.. from them.
I suppose I should add "Pentax lens may actually have a higher failure rate than this but we have no clue"..
Pentax's problem is not in a "bubble" on it's own. IF these failure rates were not known we could easily assume Pentax is all alone in it's problems. Which wouldn't be fair either in my eyes.
My SPIN on the problem.... Pentax had/has a problem effectively assembling this lens (de centering defects.. caused by in all liklihood.. cheap Chinese parts and a 3rd world assembly staff... Nobody hand collimates every lens nowadays except maybe Leica. And nobody QC every lens either.. Not C not N except maybe Leica..
Are they better or worse than other brands.. I'd say they are fairly equal if all things are considered. Unfortunately we do not have other brands (wll most of us) and it becomes personal not logical anymore.
OF course they have some issues with this lens, or nobody would have a problem.
THAT is self evident and need not be elevated above that as in it's a PENTAX problem, not anyone else's. It is and it isn't...
The lens is new tech for Pentax and there could be a combination of gasket tolerance problems, especially in changing climates, coupled with a weak or under engineered motor mount. On top of this you have the usual single part failures (ie motor) complicating the issue.
Does this help those that have failures?? No not directly. Is Pentax looking into the issue and not just ignoring everyone. Most likely. Are they going to tell us anything.. historically no.
Will new lenses be better.... they will if Pentax wants to survive...
Am I apologising for Pentax........NO...
Is a 1 year warranty a bad idea.. Yes.....
If the lens was THAT bad people would (or should be)be voting more with their wallet. No sales, no more lens...or a better version..
More effective then internet whining (no offense intended).
Since you want to keep it this lens I can't expand into other SDM lens failures...
BUT, again, no harm in looking at the track record of other companies...
