I've been contemplating some more reach than my Tamron 70-200mm w/ 1.4x can give me, and the old SMC 500 4.5 you are using was on my list to consider, along with the Bigma that Rupert uses. Since I tend to hand hold or use my monopod a lot, I was thinking the Bigma might be the better choice, or find a 400 5.6 in some variety (Pentax, Tokina, Sigma?) but I'm just not sure I will like the ergonomics. How do you find the SMC 500 to use?
Thanks in advance,

Thanks for the kind words.
I really like SMC 500 f/4.5 and SMC A 400mm f/5.6. I have both of them. SMC 500mm takes some time to master it. But once you get it dialed in with exposures it can produce fantastic images consistently.
I shoot it mostly on tripod. Not an easy to handheld, I do it sometimes when I have to. This where SMC A 400mm f/5.6 is nice, which I never use with tripod and it is easy to handheld. Both lenses produce sharp images. The 500mm gives you more reach and 400mm more flexibility.
Far as Bigma goes, I don't own it so I can't really comment on it ,, but I see Rupert producing some very fine images with it. Nice thing about Bigma that it is autofocus and it is 50-500mm (great lens).
Since you are planing to handheld or use monopod then Bigma is a great choice.
It really depends on your budget and what are you planning to shoot ..action, birds in flight then autofocus is better choice,,etc. There are some awesome new lenses out there like Pentax 150-450mm, Sigma 500mm f/4.5.
Here is older Sigma 400mm f/5.6 AF..hard to find in Pentax mount. Sigma
Sigma 400mm F5.6 APO (AF) Lens Reviews - Sigma Lenses - Pentax Lens Review Database.
I personally prefer prime lenses. There is enough high quality older Pentax lenses out there to choose from.
There is no good or bad answer here, because everybody's needs and what they can afford are different.
