Great thread as I am in the same delima . What did the OP do then ?

have a look at this :- https://engineering.purdue.edu/ece477/Webs/S04-Grp07/documentation/cfspc2_0_compact_flash.pdf Pins 1 and 50 are longer than the rest ( Power pins )  so these are the...

You can get cheap GPS units Nikon and Canon but I have never seen one for Pentax. Anyone seen one ? I dont mean external ones where you then link the photos by time but ones that write the...

Hi Ned, Nice photo's and pleased to see you are about and contibuting.

I would go with the 18-135mm , It is WR and lighter. I had the sigma 17-70mm and liked it a lot but it was not long enough for my normal lens so sold it. I also had the Sigma 18-250, it was an OK...

50mm @ f1.4 the DOF is about 5 inches @ f2 it is about 7 inches should have added at 8ft.

Of course in Japan they are available in many different colours. If  you can  find them there are a few limited edition gold ones. Also some with a bigger head so you do not miss that important hit...

I went a different route by using the Cokin system. Focus then slide the ND filter into place. Much easier than trying to screw a round filter in place. Plus the same filter works with a multitude...

I think this is  a really good lens. I had one and sold it a few years ago. It is the lens I most regret selling. -PeterGMT

If Sigma can produce their  120-300mm f2.8 EX DG OS HSM for  UK price £1995 and in Pentax fit  ( which they don't )  I would have bought it long ago,  Why cannot Pentax do something similar  ?

I must admit I have not phoned them , but their adverts suggest you can only order on line for home delivery . Which also suggest they do not keep any stock. Your right I am only 10 miles from...

Anyone got one of these ? If so what are they like ? I have been trying to find a shop locally with some in stock as I would like to see / try one before buying. Seems  like nearest place to have...

I recently did a shoot of a family ( 2 girls , mother & father ) a friend of mine also did the shoot , my studio and equipment .The family were friends of his. He took them a lot of shots he had...

Thats a very good point. never thought of that.

Can extension tubes / bellows be used with macro lens ? I have a tamron 90mm macro lens but was thinking of getting some extension tubes or a bellows.  What best  ?

Agreed, way to go

I don't know about the US, but in the UK you get free access to their technical support help line ( which I have used )  and a free quarterly magazine.

Thanks for replies. Perhaps i should have mentioned that I already hace the following lens , it's just hat I do not normally do landscapes but intend to start doing more and was interseted in what...

What in your opinion is the best Prime landscape lens for Pentax ?I love my DA 21mm but what else ?

Interesting thread. I shoot with a D700. I upgraded to Lightroom 4 a while back. All my studio shots with a white background come out off white with a yellow cast in Lightroom. They are fine in CS5...
