It's not Windows 7 related as we are using that without any problems, but that was a clean from-new install.

Upgrades are something else and personally I wouldn't upgrade the OS and would wait until I bought a new computer.

The IT team use Firefox, so it will work well with this site, but then so do IE7 and IE8.

It's interesting what is considered "suitable" for an "advanced" photographer compared to a "beginner" as all cameras will operate using Manual and Av modes if required and are equally valid.

The LX was considered to be a professional camera and we managed very well with just those two modes.

I think it's just a perception that has grown and which actually has very little to back it up. We don't need to upgrade our cameras to improve and develop our photography, all the features we need are right there in the simplest entry level DSLR.

Of course there is a difference between need and want!

Good point Stefan, it can save the day, even in IE!

As mentioned click the "remember me" box. If a post takes a very long time to complete the connection may give up, so I would suggest highlighting all your text and hitting Ctrl + C to copy it. Then click send. If it fails you can paste your text into a new message box with Ctrl+V.

If you want to upsize your files to make large prints then Photoshop will now do the job pretty much as well as Genuine Fractals will. Use a resampling method of Bicubic Smoother and results will be very impressive without the need for extra expense.

Should you need to downsize an image then using Bicubic Sharper will maintain the detail and sharpness better, especially when making images for the web.

The 75-300mm FAJ has a pleasant character of its own, but is not the sharpest of these lenses. I still prefer it to the tamron though.

The 80-320mm FA is actually an excellent lens and I'm rather fond of the one I obtained recently. Excellent for wildlife.

The 55-300mm DA is also excellent and rather more compact than the full frame lenses.

Many congratulations!

To answer the points raised about Pentax Users. This site and forum is Pentax dedicated and the forum is intended for Pentax Users and there's no intention of renaming it "ex Pentax User" so the thrust of the forum is indeed Pentax orientated.

Those who move to another marque are still welocme to join in, but they should realise that they are expected not to be here ruffling the feathers of others. It's just a matter of courtesy. You won't find me on a Panasonic forum putting down Panasonic and singing the praises of Pentax - it would be just causing trouble to do so.

Discussion that is not marque specific is found at ePHOTOzine, just next door so to speak, but the choice is there and as long as everyone can get along they are welcome to stay here.

I've moved it for you and deleted the repeated thread. Hopefully some answers will now follow!
