DFA*50 vs DA*55 (found it on internet - not my test)

URL: SLRCLUB, ??? ???? ?? ????

it is in Korean and seem to be a new test from 2018/08/06
all tested at ISO100 f1.4. you can save the photo and view its properties to see shooting information.

I might be wrong but I think, the second test shots from the last (some kind of cute birds clay) of the 55*, it misfocus.

Interesting comparison. I like the look of the DFA bokeh a little better and the DFA has better contrast, but clearly the DA*55 is no slouch.

Fascinating comparison, I love the google translate option to read the comments, might be time to have a loom at my 55 again

Interesting comparison. Granted, I am looking at the photos on my phone and I am not pixel peaking (that can wait until the morning), but there is less of a difference than I would have expected...

To my eyes the pictures showed the DFA is sharper, rounder bokeh balls and generally better bokeh. Vignetting is more noticeable on the DA*55 but thats understandable since its a APS-C lens. I have this lens on my K1 and generally shoot at F2 or smaller aperture for better sharpness and DOF. My only main complaint is the slow AF.

The DA55 is renowned for having great bokeh, and the DFA is better by a fair margin.

Photozone's historical tests of the DA*55 (which is a Jun Hirakawa design) have it vignetting less than the FA50 and the FA31.

The DA *55 is a very nice lens, the DFA *50 is clearly better with respect to wide open performance. I will say as well that I don't think the DA *55's hood is full frame compatible and when shooting it on my K-1 I turn it around. I suppose I should get a wider one, because the lens itself is pretty good from f1.8 on on full frame.

I knew this was going to be a dangerous thread to click on. It was. It has done nothing to lessen my need for the DA*55 for those days when I need to travel lighter. It has done nothing to lessen my need for the DFA* 50, even if that need is a bit sketchy when compared to other stuff, like food. Oh well, LBA 1, clickclick 0

Looks like the DA55 holds up.

A brief glance at images reduced to web size says the 55 1,4 overall, if you take into account, weight, size, portability and cost, might be the better option. And it's a lot easier to go for the 55 now that you know how it stacks up against the DFA*50 1.4, and secure in the knowledge there is not better coming for a long time if ever.

At Henry's, currently $700 for the 55,
At Henry's, currently $1700 for the 50,

If the 55 is not that cheap, the 50 is doubly not that cheap.

How good is the motor on the 55 though? I've been wanting this lens for a while, but if I wanted a very expensive manual focus lens, I'd finally get that Meyer Optik Gorlitz Trioplan...

A lot cheaper at the McBain Inventory Clearance - DA* 55/1.4 for Canadians.

Slow as molasses Optically good & you could always focus manually.

Every time I tell myself, I AM GOING TO GET THAT 55* ... riggght now! [I already put my belove FA50 macro on sale and about to reduce its price to make it easier for people to make a decision so I can move on to 55*.]


Then...I "always" see people talk about its slow auto focus which lead me to worry about the weak and potential motor failure.... now I go back to the full cycle. I am not sure again if I should go for it! I am totally agree with @IgorZI "I don't want a very expensive manual focus lens".
