I had set out to do a comparison with a tokina ATX 35-200mm but belatedly realised that the tokina has a hazed internal element, negating the comparison. But here are some sample pics, taken on my samsung NX20.
1. macro mode - taken at the cfd.
2. Conwy castle @ ~50mm, f8
3. seagull ~ 120mm f8
4. castle turret 210mm f8 pentax K5

Pentax K-1 Tamron 24/2.5

Nice. It would be great if K1 owners could show sample pics with adaptall lenses here.

The one-touch zoom design in this lens makes it quick to zoom and focus. I hope my test pictures help you a bit with potential buyers. Few things that I like about this zoom lens:

one-touch zoom design quick to reaction
small and compact, not like any 70-210mm MF zoom, filter size is 49mm
great close up down to 1:3, it can get to 1:1.5 if one gets the adaptall-2 2x tele converter
comes with a built-in lens hood
very reasonable in sharpness, ideal for Pentax use with SR, I find it more challenging to use on Sony A7 without SR
a cheapo alternative to DA* 50-135. It can't compete in quality to DA*, but I will prefer the smaller size in hiking and less bulk in street shooting
color and contrast surprisingly good
bokeh is decent for a zoom

Cheers,
Hin

Have listed the Tamron 70-150mm f/3.5 (20A) on marketplace and I have placed a hold after shooting test pictures. Those are not outstanding shots but for a $39.00 lens, I have to hold my thoughts and think it through some more. Please convince me to keep it if you happen to like this zoom lens. I know my very admired friend Stevebro is still using this zoom lens.

Cheers,
Hin

Was just told about this thread. I'm currently using a very kind member's 500, 55BB; mirror lens. I must say I really love it! These were taken with my K3, handheld! Looks like I'll be buying one of these soon!

A few more recent 52BB ... all @ 1:2

More fun with the Tamron 55B 500 F/8.

Even caught a busy bee.

**csa** · 06-13-2016, 10:41 AM

Here's a cropped version of the bee. I was about 10 feet away, hand holding the 500mm.

Pushing the mirror!

Sunset, so low light. Handheld Tamron SP 500 mirror, K3. In addition these were shot thru a window!
