Took this snap earlier today with a Tamron SP 60-300 + 1.7X TC = 510mm
The sun was setting and so I had to push ISO to 640 to compensate for a rather slow shutter, so there is a little detail loss due to NR. Though overall I'd say the results look promising...
I'm going to run some more tests tomorrow in better light to see how things look then.
PS. The camera was spot focused on the grass stock rather than the subject, in case someone wondered about the DOF. All in all, I'd say not to shabbey for a $60 dollar eBay zoom lens

I think the IQ is damn good. What was your 1.7x TC ? I've tried the Tam SP 01F BBAR flat field 2x TC before, but i'm not 100% convinced of its quality _________________ Dogs Trust + RSPB member |

This one was taken with a Pentax SMC-AF 17x TC
I tried the same lens with other 1.4 and 1.7x TC's but this one gave the best results. Plus it makes the Tamron Auto Focusing which is somewhat convenient. |

The combination could be used in AF, but since my adaptall adapter is not A(PK/A), it is manual aperture and so I am limited to MF.

I believe this was f/5.6, and the lens is 3.8 if I'm not mistaken.

This is not the limitation with this AF-teleconverter, it focuses just fine with all manual lenses, which are bright enough (users report it to work up to F4.5-F5.6 depending on the light available). So it should focus just fine even without the PKA-adapter, in this case the lens is just too dark at least in the long end (F5.4).

The lens is F3.8-F5.4.

Indeed.
If I had a PK/A adaptall mount, I could shoot without stopping down and it would most likely work all the way to full extension. However, my own experiences have shown that at/or around 5.6, AF is really borderline in terms of usefulness. At which point it really only works reliably in very good light.
But with my particular PK adaptall adapter, I am at the mercy of two forces that work against this TC being AF. The first is where the adfaptall mount(flange surface) is powder coated. Which prevents the contact pins from being shorted out this stopping AF, The other issue is where I must stop down manually with this lens, therefore... the TC AF function is not an option with this particular combination.
I also know I could short the pins on my camera using tin foil(or equivalent) but I'm just not big on rickety modding when it camera hacks. But given these results, I think this lens warrants picking-up a PK/A adapter off eBay or similar. |

Thank Attila. He's behind it all. Copied the site to a new server after the old one was lost. _________________ DSLR: K-5,K20d+Grip, Ist*Ds

I really like this lens. Using it on a Contax is very easy especially as it is surprisingly light given its focal length.
I've also used it on my Olympus E-3 with a 4/3-Adaptall 2 adapter and am awaiting a M4/3 adapter so that I can pop it onto an E-PL1. Having in effect a 120-600 zoom is very useful.
It is sharp, offers good contrast and distortion is well-handled for such a zoom length. And current ebay prices represent a bargain for such a good quality lens. _________________ Contax RTS/Zeiss lens fan and constant user along with my Mamiya RZ67 ProII. Favourite lens: Zeiss Planar 55 f1.2. |

The FOV gets cropped, and by how much depends on your crop factor, but thats it. There's nothing that i know of that magically increases focal length of a lens when its mounted on crop cameras _________________ Dogs Trust + RSPB member |
