Tried mine quite a while back Kris and wasn't too impressed as a large percentage of the correction is missed. There was a thread about it and John Riley mentioned the lack of correction due to crop factor.

By the way, great image.

IQ was well acceptable but the 50-135 had to be in manual, then pre focused to somewhere near with the AF1.7 then locking on. My main surprise was the vast increase in speed of the focus on the K7.

As far as dialling in the FL with a TC or switching off/on to try to get the right FL for the SR, I think not. There is other kit that allows you to get the results as the horse passes the line rather than on its way back to the stables. I suppose it works well for telephoto + TC shots of static structures or stuffed birds for the wildlife fraternity.

The comment about the relevance of Canon lens testing with TC's for Pentax is only just valid as Sigma make a DSLR. The fact that they happen to make lenses to fit other makes is of benefit to the other makes.

How many Pentax users would use Canon or Nikon glass if they decided to produce it to fit Pentax DSLR's? I would imagine quite a few people as there's no shame, since a lot already use Sigma glass.

Aye, the square is the finished item. The tree details caught my eye as well as there seems to be some horizontal branch lines there. just slightly different to the normal or expected branch directions.

Great set Tim as usual, well presented and finished.

TJ has to be a winner.

I've cancelled this weekends Marlin fishing. This is much more entertaining. The Op's are like spiders webs, make contact and be caught.....

You probably need to consider a different system. It comes down to using the right tool for the job and at present, Pentax do not offer the right tool as far as glass in concerned.

The down side is cost. Long, fast glass with or without matching TC's means large sums of money.

Spotted this on another site that also linked to the Flickr image.

The owner said;


“That was from one of my avian photography sorties. I use a floating blind to take photos of water birds but the water level that day was very low so I had to crawl it out in the mud to get the photos that I want. I was constantly pouring water on the LCD to take away the mud so I can view my photos. The lens installed on the body is a Nikkor 500 f/4 VR. After the shoot I cleaned the camera and placed it in my dry cabinet. It still works flawlessly: all seals worked, not a single grime inside the camera."

Bravo and a beautifully themed image.

I can't believe that the OP generated so many answers.

It's better than Marlin fishing of the coast of WA.

Easier said than done. You will need new glass and due to the issues in Japan at the moment, some prices are going up.

What exactly do you "need" in the K5 that you can’t get at the moment?

I have seen the lab results etc. for the K5 and it's a fine piece of kit. It's brought Pentax into the same classroom as the other hi ISO low noise candidates but it's not at the front of the class.

The majority of shots taken by owners of the K5 are no different to those taken with a K7, K20 or K10. The greatest need is probably for using long slow lenses like Bigmas, in less than good light (I have a Bigma and seldom use it). Hi ISO is no excuse for slow glass.

As you have a 150-500, I assume that you find it too slow and are looking for the qualities of hi ISO and low noise. Yes you will see an improvement. To consider a D7000 is fine and you have a whole group of fast glass options plus the single option of the costs involved.

I bring up the cost as you seem reluctant to pay GBP999 so how do you rationalise paying at least 2.5x more by using another system?
