Can't believe someone (from the UK) paid £257 for one of these last night on ebay The Adapter didn't have and endcap (std. body cap) and because the elements are floating they could easily get damaged. The seller had a feedback of only 14 Seems like Pentax need to get this back in production...

Note this is an Adapter not a Converter.... It won't work on a manual camera. (needs AF to Focus). shim It works fine on a manual camera. But obviously it doesn't focus for you. G

As long as it's not hunting and trying to focus it should be OK, It's just if manual focus is at all possible and it would go out of focus if the lens cell moved. shim

Just thought..... It can't be trying to focus because you will have switched the camera to manual so that won't be a problem. The lens cell will only move between two stops so nothing should get damaged and it can't fall out. You might struggle with the range of focus available. Push on the lens ...

Last night I mounted my 77mm Ltd on the 1.7 T/C, switched the camera to MF, and was able to focus on everything from my computer keyboard about 18 inches away, to the moon. I didn't try anything further away. G

Which 500mm for wildlife?
I was looking round for one and most people had no stock and told me that they would be comming back in at £1000 plus, I was lucky enough to find one in stock and still at the £700 it was just after Christmas. Am still trying to come to terms with it but I am getting there.

Which 500mm for wildlife?
Another vote for the 150-500. I find the focus excellent - quick and virtually silent, and with my limited talent, the IQ is just fine. You will need a substantial tripod if you use one, or some Weetabix. Mike - what's your fee for a DA 12-24 :wink:

Great Blog Neil and some good photographs. I'm amazed how close you got to that Heron. The closest I've ever been is about 25m. What camera and lens did you use on the Heron shots? You need to sort out a title for the page tab and bookmark.... it just shows - by Neil shim Thanks much appreciat...

Pentax 17-70mm v Pentax 16-45mm
Both are great lenses. I have an early 16-45 and I've had some lovely images from it. Recently got the 17-70 (with cash back :D) and that's pretty much my favourite lens. Very capable. However, it tends to underexpose a fair bit (needs +0.3 to 0.7 compensation generally). Contrast, colour and resol...

Pentax 17-70mm v Pentax 16-45mm
I got the 16-45 last year, and was very happy with it. But shortly afterwards was tempted by the extra-reach of the 17-70 as an all purpose lens for when I'm travelling and it's dusty. Incentivised by the £50 cashback and further tax deductions due to my non-UK residence status I got one from SRS wh...

Pentax 17-70mm v Pentax 16-45mm
This is about a 1/4 crop from the original. ISO 560 70mm f/4.0 1/60 Can you confirm if this is what is expected from this lens ? Thanks I don't have a Yahoo account and don't sign up for one. According tot the German magazine Colorfoto, the middle range is the best part of the lens. T...

PENTAX OR TAMRON
My daughter and I both have Tamron 28 - 300 lens`s. Mine on a K10D, hers on a K200D. We are both struggling with focus, they just don`t seem to be that sharp. I put a couple of my shots on the gallery using the tamron. The one with the Pentax 50 - 200 is sharp not `soft` like the Tamron. Scott is su...

PENTAX OR TAMRON
Hi Cedric, I have a Tamron 18-250 on my K10D and I am really pleased with it. There do not seem to be any issues of soft or unsharp focus.

PENTAX OR TAMRON
I have an old (non Di) Tamron 28-300. It is back on my Ds now as my husbands lens of choice but I have never had any problems with it, even on the K20D. Maybe the newer lens gives problems. From what I have seen here the Pentax 55-300 is a really good lens, and may be worth your money - you could...

PENTAX OR TAMRON
I tried checking the focus using a metric scale rule and the camera at 45 degrees. I focussed on the 10 centimetre mark with various aperture settings. The focus is fine but what I did notice is that at the 8 centimetre point and 12 centimetre point it was becoming out of focus. This indicates that ...
