No problem Rob. See here on Sigma's site for an explanation of APO.

Is that definitely the APO version from Jessops? Seems a little cheap to me, I paid £158 for mine.

Hi,

I have recently purchased the Sigma lens for my K100D and have to say I am very pleased with it so far, the image quality is great and the sharpness at the longer focal lengths is excellent.

I had looked into the Tamron lens but I had read that chromatic abberation was a problem at the longer focal lengths. There appears to be a little purple fringing on the picture from iceblinker near the top of the tower.

Your best bet, which I done is to go somewhere where you can try before you buy. I purchased mine from Calumet, and although it took a few weeks to arrive, it was good to have a chance to see how the lens performed before I parted with my hard earned cash!

Definitely P series, with the 18-55mm kit lens, you will probably notice vignetting with the A series at the wider angles.

I have the P series filters and they are fine at the wider angles.

Hi all,

I am really getting into landscape photograpy at the mo and have recently purchased a tripod, some Cokin P series ND filters and ND grads. I am also looking to purchase a circular polariser, looking on eBay the Cokin P series ones go for around £40-50, whereas the Kood ones go for less than half that. My main question is, are the Kood ones any good, or should I just pay for the Cokin one and not be a complete scrooge!

Your advice appreciated.

Hi John,

I did do that with the lasso tool, but there is very little if any detail left in the white clouds. Methinks I'll have to go back and hope for a day not quite so bright or use an ND grad filter. I did actually have one with me, but I was too lazy to attach it!!

Took these photos a few days ago on my K100D, converted them using the Photoshop channel mixer and adjusted levels afterwards. The sky on both of them is a little burn't out, should've used a grad filter. Let me know your thoughts and how I could improve the framing...I know I cut the top corner off the building on the second pic!

TIA

Hi all,

I have recently purchased an Epson Stylus Photo 360 and am so far very pleased with the results. Does anyone have any experience of the quality of third party inks? I have read that JetTec inks are extremely close in terms of quality and colour reproduction to the original Epson inks.

Can anyone confirm this for me?

TIA

Took some shots today, weather wasn't too good (typical British bank holiday weekend!) so took some out of the window. Quality not too bad considering they are hand held at 300mm and through a double glazed window.
