After reading 100's of reviews about similar lenses I recently bought a Tamron 17-50. I read that the quality can vary but the good ones are really good...I must say I very very pleased with the overall feel and sharpness of the images. The build quality isnt that bad either.
They are certainly cheaper...but I wouldnt say they are cheap
Its on my K20D all the time right now.

Hi all, I am sure this topic has been covered before but I wonder if anyone has experience of this particular lens? I am soon to be in the market for a wide angle zoom. I have read all the reviews and at the moment I am leaning towards this Sigma lens. I would appreciate any feedback. Kind regards. Mark

Inspirational stuff Shaun, some amazing shots..many thanks for link.

Kind regards
Mark

Thanks for the advice chaps. I wont be leaving it attached when not in use,
it wouldnt fit in the bag still attached!
I dont think its a great lens anyway, but I'm going to give it good run before I sell it!

Hello Hubert,
Welcome from Chichester.

Its a very useful site, I am sure you will learn anything you need
to know here.

Whereabouts in China are you? My wife is Chinese so we go there often.
Thats why I never have any money for new lenses!!!

Looking forward to your contributions in The Gallery.

I have been after a wide angle budget lens for a while and decided on a M28 3.5 for now, tried on ebay a few times but no joy below £50....anyway, just happened one night I noticed an ad ending in 20mins...was a collection of M28 2.8, M50 1.7, x2 converter, assorted Hoya filters and other bits and bobs and a lens I knew nothing about...Vivitar 100-300 f5.

To cut it short, I got the lot for £41.00!! good deal I think? I have a M50 f2 but apparently the f1.7 is a much better lens?
It was like Xmas arrived early unpacking everything
The Vivitar is a heavy beast, bit worried about putting on my K20D!
M28 2.8 seems fine for now.
In future, when funds allow I would love a DA 16-50 to go with my DA 55-300,
Seems bargains can still be had on ebay what do you think?
Thanks for reading.....baby crying now!!
Regards
Mark

Stan, are you from Newcastle??
Let me guess, you are taking the photo in your Speedo's?

Thanks for comments guys. Yes it happens when you switch on and off after a short interval.
I guess its off to the repair shop!

Hi
Wonder of anyone has experienced this before.
I've had the K100D for a year now without any problems.
Just recently when I turn on, the screen comes up with the screen for
setting the date/time. Never happened before.

I set the date/time but when turned off and on again it goes back to the
default date which is 2006.

I am setting correctly, ie pressing OK and not Menu.

Any ideas?
