So I guess its the 1.4TC that should be considered. In some sites they mention that 2xTC is not good at all with the bigma.
Still 700mm is not bad at all, that's what we get with the 1.4TC
Have you seen these images? I think they are a bit on the soft side link

You mean the Sigma 1.4x and 2x EX converters on the Bigma Amin?
With the 1.4 it would give 700mm .
Although not sure if it wouldn't be pushing a bit with the 2x but if it worked that would be a whoping 1000mm. Even if quality suffered a bit but for bigger subjects that would be quite a coverage

As I said, I'm not having a go at the Bigma, as a virtual one lens solution I think its excellent and I have had very good results. Considering the detail in the door lock and that it's a zoom lens had I not been purposely comparing the 2 lenses I would have been more than happy with the quality.(actually I still am).
When you have time to test some more like you said with tripod are you able to stick in a TC to it also and see how it performs? . That would be the cherry on the cake

It's hard to judge handheld shots. I have been playing with my Bigma and it is really difficult to use it handheld.
One has just to look through their portfolio of wildlife and you can see all those birdies taken without tripod

The K-7 will not be full frame, I would put Amins shirt on it.

I will see if I can get the tripod out tomorrow Amin and do it properly. I may introduce the A* 300mm f2.8 into the mix as well.

The 300mm with the TC is definitely sharper compared to the bigma shot. Unless there was a bit of shake induced blur into the first shot, but just look at the wording on the padlock where it says "MADE IN CHINA". When you compared those spots the difference is visible.
But I might be wrong, could be just my eyes playing tricks.

Reason for sale? ha, you guessed it, ended up buying extra kit that now its small for my purposes. I bought a Tamrac Expedition 6x a couple of months ago when I bought the 300mm lens.
This is an exceptional bag and I bought it due to its versatility and I held on to the 3N1-20 for this long even though I had the Expedition 6x, for my occasional outings without the long lens. But now with the 60-250 almost permanently attached to the camera the Kata 3N1-20 is just not suitable, so I am upgrading to a 3N1-30, although I still have the Expedition 6x.
Price £50 plus postage costs. Will accept paypal, bank transfer or cheque.

Actually Amin I rather like those.
I think we sometimes get too wrapped up in how sharp an image is when we should be concentrating more on the picture itself.
Thanks Mike, that made me look again and I see your point. We do get engrossed in sharpness issues and end up having tunnel vision.
The background on those images are quite nice, and if those were shot from a distance where the smaller range lenses wouldn't have managed a good image then bigma and 2xTC is still an option where good light is available. Losing 2 stops might not matter a lot in those circumstances
