Was out and about at Kew on Sunday - did see three other Pentax cameras! Wondered if they were on this forum!
What do you think of these three, comments appreciated:
Evolution
DA*16-50 (Hand held @ 1/6)
In the blink of a bird eye
DA*50-135 (cropped)
Not a good shot as not sharp, he was having a dust bath. Was surprised when I looked at the photo, though it was dust, till I looked closer!
Golden Pheasant
DA*50-135, Metz 48 flash
Managed to get within three feet of this bird, he was on one side of a tree and I the other!

My K10D has this issue, noticed it some time ago. I never though of it as a problem though and it has never impacted on use or performance. Also, in that time, it has not got worse.

One way to keep the cost down is to look as a filter system such as Cokin P or Z system, then you will only need one filter to cover both sizes. The downside of the system is that you can't use your built in hood, however most systems do come with their own hoods as extras.
The other aspect to consider is how often you will use the filter. I have the Cokin P system with a Circular Polarising filter and it works very well on 52mm and 62mm. I am actually going to try it today on 77mm.
The Z system is larger and more suited to extrime wideangle. I will be testing at 16mm.
Just google 'Cokin'.

I noticed this same issue with my Sigma 18-200mm, when focussing at about 3m it had a very simular field of view as the DA*50-135! However at a distance of 100+m it was a very different story!fengyboy wrote:
Well the exif says 250 at full zoom. Unfortunately I dont have another 250 mm lens to do a comparison shot.pschlute wrote:
Something I have just noticed. When turning the zoom ring from about "235" mm to 250 mm , I can see very minimal movement on the zoom extension, but it does move. However, through the viewfinder, there appears to be no change in zoom length this final bit !
Anyone else confirm what they see ?
Just received mine this afternoon, I noticed this issue as well. I guess we should call it 60-235mm rather than 60-250mm.Something I have just noticed.

My extension tubes are manual so I cannot test with a lens without an apature ring. I have used it with a close-up lens but got better results with my Sigma 18-200. This was mainly because of the closer focusing ability of the Sigma.
However, you have got me thinking. If I could find auto extension tubes that have all the contacts, then I would be very interested in thoughs here too.
I have been considering a Macro lens and have been impressed with the close focussing ability of the DA* 16-50mm!

I have the 16-50 DA* and that also suffers from some CD, however I use Paintshop Pro X's CA removal function on the JPGs and it works a treat, a complex function requiring as many samples of CA area as necessary. However I have only really noticed the purple form of CA and this is probably the easiest to remove.

It is my favourite lens and I have never had a complaint, except for an aching arm from carying it all day!

I do gather that there are some that cause a problem, however I am not aware that this includes Sigma mirrors and I know for a fact the Tamron one fits. I can post a picture if you like, though that will have tobe tonight, and I will have to use my phone to take the picture!
