Sigma vs Tamron

Thank you all for your comments! In the end I went with the Sigma and now for the sake of any once else looking to buy one I shall talk about my first impressions with it.

My first experience with the a sigma 70 - 300 was a few years ago when a friend had a Nikon mount one attached to a Fujifinpix s2 pro I remember the auto focus being very slow and quite loud it would aso hunt for a while, since getting my own one and mounting it on my K5 it handles much faster in terms of focusing and it also seems to be of better build quality, the nikon version had plastic mount where as my one is metal. I have yet to load any images taken with this new lens on to the computer but from the look of them on the camera screen they look to be fairly sharp and only light firing when shooting back lit subjects.

So far I am quite pleased with the lens and its focusing performance especially reading lots of reviews saying it would "painfully hunt for focus" If you are looking to buy a 70-300 and are on a budget then I would have no problem in recommending the Sigma. The physical build quality of the Sigma is also better than expected I had anticipated very cheep plastic that is remenicant of the milk tray box but it feels sturdy and robust.

Hi.

At the moment I am looking to buy a zoom lens and I am currently looking at ether the Sigma 70-300mm GD macro lens or the Tamron 70-300mm Di LD lens, they both retail on amazon for around £99.00 they both claim to have macro focusing abilities.

I would like to know what one you think is better over all in terms of sharpness focus speed,, build quality ect.
I will be using the lens on a Pentax K5.


Thanks.

K5 white balance problems

In post processing I often try a few different white balance settings (just to see what they look like) and on this particular occasion I found that tungsten was the closest match to what I remember the camera had recorded.

K5 white balance problems

so, I have had my k5 for a few days now and so far it is a wonderful piece of equipment but when ever I use auto white balance the K5 gets is wrong, really wrong. Fortunately I shoot in RAW so this is not that much of a problem but as an example I was out shooting today in slightly overcast conditions and the auto white balance thought that tungsten light was a good idea.

Is their something I am doing wrong? Is their some setting in the menu that I might be able to change? Its not a big problem its would just be nice to have to change the white balance all the time.

Thanks for reading.

I was aware of this, I just wanted to see how the Pentax software was in comparison to raw processing in light room or Nikons View NX 2

My K5 is scheduled to arrive in about a week and in the mean time I want to see if I can become familiar with the Pentax photo laboratory, however I don't have any PEF files to open with it (only have NEF as just switched from Nikon)

does any one know where I can download some PEF images for me to edit and see if I can get to know the workings of the photo lab?
