Can't tell how much sharpness is lost using the DA TC1.4x. But I can say sharpness is good enough for me. An example ...


KP • (DFA150-450 + DA TC1.4x)@630 • ISO100 • f/11 • 1/13s • ES
tripod use • manual focusing, controlled via LiveView • cable release


and a 100% crop ...


There are many parameters that can influence the sharpness. At APS-C/630mm you get a field of view of around 2.1 x 1.4°. The slightest vibrations can yield some smoothness. Hard to say if this was a perfect in focus shot.

And one at f/8 ... a bit nearer ...


KP • (DFA150-450 + DA TC1.4x)@630 • ISO100 • f/8 • 1/125s

What are the chances that the DA* 11-18mm will be FF compatible?

A zoom lens can only get the FF designation if all focal lenths at all apertures offer the fullframe image circle. Since the filter thread of the DA*11-18 is 82mm, I guess the chances are good that it offers the FF image circle partially like the DA12-24. We‘ll see.

55-300 PLM and... Help me spend my money?!?

I bought the 55-300PLM when it reached the market and at the time wrote some PF posts and a blog article (german) on my website about it. Within it’s range it even delivers very well compared with the DFA150-450. First I used it only with the K-1 and some months ago I purchased the KP mostly for more lightweight hiking.

IMO this lens delivers in every respect. My hiking set now consists of KP, DA15, DA18-135 and DA55-300PLM. If I want to go less heavy I only take the KP, DA15 and DA18-135 with me. The KP / DA18-135 combo covers all angles of view that I got with ME Super, M28, M50, Viv 70-210 - that‘s really great!

Is this allowed? For some foto competitions it surely wouldn't be. I sometimes like to experiment. And one of those experiments is to simply invert the values (complement, a photo negative) of a capture within the RGB curve tab in Capture One by setting input 0 to output 255 and 255 to 0 (linear function) as a first step and then model the curve and other parameters to my liking.

Here are two results. First a color version, second a black & white version. Results can really be surprising. But have a look by yourself. :) :o
