I've had a 16-45 for some time now, but I have never really gotten too confident with it. The strange thing is, everyone seems to absolutely adore it. So why don't I ?
I did search this forum looking for someone else with a similar experience, but didn't seem to find any. The only one is a guy with a review that claims it was soft. Sounds more like a back/front focusing issue than my "problem".
A lot of people talk about prime like iq on this lens, and while I do love prime lenses, I can't say my copy gives exactly the same feeling. It's quite difficult to put into words, but I'll give it a try. Most images turn out sharp, but they do seem to lack a bit of resolution. I think of it more like drawing with a thick pencil sometimes.
After studying my images taken with this lens I have found that one of the main reasons I'm not too happy is due to a rather harsh bokeh in my opinion. Out of focus areas seems to be very contrasty and full of action instead of smooth buttery cream. This is easily provoked by shooting some grass, leaves or even stone surfaces. I have checked images found online that are shot using this exact lens, and others seem to produces the same artifacts. I'm however not sure if all 16-45s produces the same amount. Images taken with the 16-50 in correct working order seems to be way better in this regard, much more like a prime lens. The funny thing is that I seem to even prefer images from my 18-55.
I will post some images later for better explanation, but I really have to get some sleep first. (it's 01:33 am local time..)
The reason for posting this is just to see if anyone else has experienced something similar with this lens. It could be that I've just got a bad copy, but I can't really say exactly what is wrong with it either. It's all just a subjective feeling I get from watching images. As long as I'm not confident with it, it will have to go, but I don't have the heart to sell it to someone if it really is a bad copy after all.
Note: Please. Dont make this into yet another stupid thread on how terrible Pentax products are, and how the world is coming to an end. I'm trying to find answers to something that has been on my mind for quite a while. I'm not bashing anything, for all I know it could just be my head there is something wrong with.
