What lens should I buy next?

As you can see with the lenses I have listed below. A lens in the range of 50-150 is needed.

Requirements:
- Not too large or heavy, as I can always use my sigma 100-300 instead.
- AF for sure...MF is not for me.
- High quality lens with the highest IQ.

I am considering the FA77 or Tamron 90mm macro.

My FA 43 is so tack sharp, that I can crop heavily and still be fine with it.
So, what is 77 and 90 going to give me that the 43 crops cannot.

Then I am thinking along the lines of a 135mm prime, the best candidate seems to be the FA 135mm f2.8, but they are difficult to find and I am not totally sold on them being equal to the Pentax Limiteds. Is there any primes close to 135mm that can rival the limiteds ?

I want to get a lens when the FA 43 is just too short and I really don't want to pull out the bazooka (sigma 100-300)

The 50-135 and 70-200's are too large.

Is there any choices that I am missing?

Thank you.

As good as the 43ltd is, a crop from it is not going to quite match the native
magnification of the 77ltd. You'll start to see a bot of noise, also, when you crop
too much to try to match telephoto effects.

Also, you can consider this - with the 77ltd, you can crop even more, out to
135 or even 200mm equiv!

The following is a tight crop from the 77ltd, about the equiv of 200mm:





Here's a 77ltd snap, with a crop out to about 135mm equiv following:

The 77mm was my number one choice. There has to be a reason why so many Pentaxians pick this as there favorite lens...the crop of the guy is very convincing, so I went ahead bought it.

Just needed that last nudge I guess

Thanks. Black, just like my other FA lens.
