I have, and regularly use, the same combo. Post some examples. This is the club. Let's figure it out.
I'll dig some pics out of my library and post some here ... we shall see what the jury will announce !

That is going back to last summer ... last time I used this TC/lens combo. (I almost put it up for sale ! )

Thanks for the reply.

Finally did some testing with the F*300mm f4.5 and the HD TC 1.4x last sunday... (xposted)

I was using a monopod
SR was on

@ F6.7 F8 and F11 respectively... Just applied AutoTone in LR5 no other PP.
I plan to compare a couple of long lenses and post results on the forum. Looking at the pictures I really like the fish hook with line the best. It seems to really highlight the difference especially on the lines. I think I would do a series with manual focus using focus peaking along with auto focus.
The guard rail shots also look very informative.

I would appreciate your thoughts on test shots to compare long lenses.
Thanks

HD DA AF RC 1,4 AW on FF with DA 10-16

Without the TC the DA 10-16 vignettes badly below about 14mm. The attached images are at 10mm with almost no vignetting.. On A7II Excuse the dust. Xpost from Pentax on FF club.

I admire those shots taken with lenses/TC combo

but .... I have no idea why I have yet to get ONE single decently sharp image with this TC and my DA*300/4.
Well ... maybe one or two half decent among maybe 50 to 60 shots.

I fought with mine as well. Some would be track sharp, so not the lens/tc. I finally figured it was shutter vibration. At about 1/1600 it is fine, but we rarely have enough light for that. I sold mine to partly fund a sigma 500 4.5.

That cannot be. I have thousands of pixel sharp images with the K-3, DA*300 and HD 1.4X TC, below 1/1000s shutter speed.

Interesting that the EXIFs show like only one TC was used (784mm), where the stack of 2 TC's should have been something like 1098mm...


But the results are pretty impressive !

Quick astro shot with DA*300 and 1.4 HD TC

10x guided astrotracer shots at 10secs 6400ISO each. Stacked and averaged in Photoshop. A slight crop.



More shots (many more) to stack would have been better, but the clouds rolled in!

Really nice set, zzeitg. That last one blows me away. What kind of bird is it?

Thanks! The bird on the last one should be "European goldfinch". It's a rare visitor, he's not showing himself often (well at least not in our garden).

Really nice set! Care to share the settings you favour for this kind of shots, zzeitg?

I seem to suddenly not be able to achieve the quality I was getting for garden bird shots with this combo (K-3, DA*300, 1.4 HD TC), and I wonder what I am doing wrong. Think I may need to start with lens calibration.

Thank you!

Concerning the settings, I think there's nothing special to be mentioned.

I usually shoot in AF.S (continuous shooting(H)) and TAv mode.
Starting with 1/1000 and F5.6 or 6.3.
AutoISO - 100-max. 6400.
AWB.
In worse light conditions I increase exposition up to +1EV.


SR ON, monopod is a good friend.
Many times I focus manually (AF is sometimes hunting on DA*300 (or K-3?), more with than without 1.4x TC).


But probably the most important point is trying to get close (to avoid excessive cropping). I received this hint here on the forum some time ago, so now I'm only passing it on...
