Originally posted by papillon_65 I guess you didn't read my post properly, I take lens tests with a pinch of salt, at best they are only a guide. Nothing compares to using a lens in reality, and yes the 16-45mm is streets ahead of the two 18-55mm's I own.
I would not disagree with you that your own tests are the most valid
- for you.
Professional tests out there are a guideline - one can accept or reject them.
They normally have specialized equipment to measure more objective things like MTF etc -
are standardized, controlled, and within reason repeatable
- the same cannot be said for our own tests.
But I have already agreed one's own tests are the most valid
for oneself.
I do not doubt your dissatisfaction with your two sample of the 18-55mm zooms -
and I cannot and was not arguing with with your opinion.
The only thing I will say is that I also have two 18-55 - and they seem to give me satisfactory results - and I would be the first to agree it is not the "best lens in the world" and I know it's a mere budget lens - but it seems to give me good results - that is also only my opinion.
So it comes down to opinion -
and I have offered samples and tests results to help support my opinion -
but it is still only an opinion.
The only other thing I would add is that Pentax supplies this lens with just about every dSLR they sell
- yes, being "cheap" is a major reason -
but please also look at it the other way round - it cannot be too much rubbish
- as they are staking their reputation on that lens
since it is the most abundant and their most used lens.....
seems to me to be a very risky thing to do if it were really rubbish?
