They also do a faster, cheaper 500mm mirror lens: http://www.amazon.co.uk/Opteka-Telephoto-Mirror-Digital-Cameras/dp/B00281OE1K/re...=sr_1_5?ie=UTF8&s=electronics&qid=1276953554&sr=1-5

I'm slightly tempted at that price, f6.3 isn't much slower than my 300mm zoom (f5.6). Presumably mirror lenses have a fixed aperture?
As John says, yes, fixed aperture.

I have a 500mm f6.3. It has very low contrast and insanely thin DOF. As a result, I tend to use it on my GF-1 as my focussing screens in my K20s are off by a tiny bit but I can't be bothered to buy shims - so when it looks good, it's fuzzy in the taken image. Sadly, the green hex doesn't appear to work with it - I'm willing to be corrected.
The GF-1 uses the sensor so when it's on focus, it shows as on.

I do have a couple of questions/opinons that I hope people will respond to:

1. I am looking for a flash for my K10D camera. What are everyone using?

2. I was looking to upgrade/add to my arsenal the K7. Is it worth purchasing the K7?

I look forward to read more of the forums.

Thanks,
John
Welcome John,

1. I use a AF360FGZ (now) with an Orbis ring adapter.
2. Can't comment - I'll be sticking with my K20Ds until they die - then I'll make the jump up.

Once again welcome.

Interesting article here http://www.kenrockwell.com/tech/raw.htm
At the moment I am shooting raw + jpg.
I find it easier to manipulate the jpg but I have the raw file if needed later.
I suppose as i progress I might change how I do things.
I wish I could mark your post as 'contains a very good link'. Thanks Pete.

Enjoy, do show us some pics then.
OK - wife looked like she'd bite my head off - no portraits. So off to the garden which is soaking wet after the legendary Cambridge April showers (yes, if May Balls can be in June, the April showers can be as well).

Composition is crap and the lighting off on one, but I love the softer shadows.

Hi,

Saw a sidebar ad for the Orbis ringflash adapter on this site. I did extensive research:-

i - Do I have enough cash? Check.
ii - Does Amazon stock it? Check.

So it arrived. Insane fun. It's lovely being able to take macro shots at f32 and portraits are much more natural. It's breath of life into my 50mm macro lens and I'm going to be playing with this a long time.

Thus begins one of my major gripes with Pentax and Sigma. I would dearly love a HSM/SDM macro lens in the 150mm to 180mm range. Pentax don't seem to think it worthwhile and Sigma did the unthinkable - a beautiful 150mm HSM Macro but the odd one out mount isn't Pentax but Four Thirds.... Also the 180mm has been discontinued.
I have the 50mm macro, but it gets so little use as the 1:1 close focus distance is much too close.

I think it has the definite beginnings of a great shot - just a crop (preference being top right) and dodge/burn to enhance the contrast in the mussels and I'd be happy.

I chose Pentax because they use all capitals in their logo. Unlike either Canon or Nikon.
And the decider between SONY and PENTAX was?

I think it may just be that anyone who thinks a given brand of camera is necessary for capturing EM radiation and possibly that EM radiation looks at the marque of a camera before travelling down the lens just doesn't quite 'get' what photography is really about.
