SMC A50mm f1.2 vs FA 43mm f1.9 limited
The bokeh on the 2nd one shows why this lens is so popular. Certainly not a 'gimmick' :mrgreen: bjolester, congrats on joining the 1.2 club :) - You won't regret it. Try it on some street scenes @ 1.2 too when you get chance. not easy to focus, but when you nail it, it's great :)

bjolester, congrats on joining the 1.2 club :) - You won't regret it. Try it on some street scenes @ 1.2 too when you get chance. not easy to focus, but when you nail it, it's great :) Thanks! Obviously this lens has its strongest selling point being f1.2. But based on my initial shooting today, th...

SMC A50mm f1.2 vs FA 43mm f1.9 limited
Sadly, I find the out of focus highlights quite unpleasant, so that wouldn't be for me. I think the lens handles darker out of focus areas much better. It's a pity that manufacturers aren't more forthcoming as to what any particular lens is actually designed for. The "Pentax lenses and Accessorie...

Hey, Smeg, thanks for making my point for me. Not that these aren't all immediately "bad" photos, but they are far from how good they would have been at a more reasonable aperture. Coma, halos, fringing... it's all here. No they would have completely lost the effect I wanted at what I assume you...

No they would have completely lost the effect I wanted at what I assume you would call a reasonable aperture, so no they wouldn't have been as "good" - I make a concious choice to use F/1.2 as I like the artistic effect and don't worry about the aberrations the lens has. Thanks for going a bit furt...

SMC A50mm f1.2 vs FA 43mm f1.9 limited
There's something satisying about getting that subject 'pop' against the background straight out of camera, and it's quite an involved process to get it to look perfect in photoshop - with some subjects at least. I am open to the notion that the fast lens / big sensor 'shallow dof on wide angle' ...

SMC A50mm f1.2 vs FA 43mm f1.9 limited
Yes - the reason the K50 shot works is her pose and the good background, as well as the lens rendering - which is lovely. Not the f1.2 setting. In fact I suspect it was shot at more like f1.8 to f2? In terms of the 'pop', I mean when the background is pushed back by a selective narrow dof on the ...

... 'ere's the 50/1.2 Buggy shot with the fringing removed. Took about 10 seconds in LR4. Note: I edited the jpg export I posted yesterday as the RAW is sitting on back up hard drives in a safe place and I couldn't be bothered to hook them up to the computer just for one image :)

Another selection of F/1.2s :) Interesting subjects and locations! Great testimony to the focussing, and of course the photographers quick eye and shooting! I do find the extreme out of focus areas odd though - actually rather distracting when I guess its actually meant to be the opposite. Some ...

SMC A50mm f1.2 vs FA 43mm f1.9 limited
Fixed :D That was a very extreme example as well probably maximum black against an overexposed highlight. ' But its not really, is it ? Lightroom has only dealt with one element of the PF - that is the purple tone. The rest of it remains, and is clearly distracting in this context.There is a clear ...

Well yes OOF areas are technically an aberration and as said Lightroom isn't magic dust. It can remove PF excellently as is seen here, but it can't put OOF areas back into focus ( sadly ) When using LR to remove PF on in focus, sharp regions, those regions are left in focus and sharp. It's only c...

I would repeat that Lightroom cannot put something back in focus where a normally sharp edge is many pixels wide and blurred because it's out of focus. When using LR to remove PF on in focus, sharp regions, those regions are left in focus and sharp. There is no grey fringing left.

Not opinion, but fact, optically the 43mm Ltd and the A50mm f1.7 have pretty close resolution figures with the 43mm being just slightly sharper (hardly any difference really.) The 43mm is closest a normal focal length and is a fully auto lens so auto focus works whereas with the A lens you'd have t...

manual very sharp macro lens
Vivitar 55mm, 90mm and 135mm close focus. They come in a number of aliases. Check reviews over on the PF site.

manual very sharp macro lens
Agree - not sure a longer macro is the right tool for product photography. The SMC50/4 M macro is a lovely little 1:2 lens though, and barely larger than your 50/1.7 until you focus close. I'd also second the suggestion of the Vivitar 55/2.8 - a superb 1:1 macro lens manufactured I think by Komine...

Been looking at 150-500mm Sigma - Scratching issues
Been looking at the 150-500mm Sigma and it appears to scratch very easily. Has anyone used this type of Neoprene cover ? http://www.lenscoat.com/lenscoatsuptmsup-sigma-150500-p-856.html There has been 2 types of coating on Sigma lenses, the old matt type finish and the newer smooth plastic fi...

Current state of affairs - Warning lens P0rn!
The Voigtlander is likely the ultimate. My fave of those I can afford is the "Vivitar 135mm f/2.8 Close Focus" in M42 mount. Looks like this: And this (!): It's actually a 1:2 macro lens. But Vivitar didn't want to brag, and so say merely "Close Focus". :-)

Current state of affairs - Warning lens P0rn!
Rendering is very nice right out of the lens. Perfect for portraits if you can get far enough away from your subject! Built like a rock. Smooth focus. Detail, colour, bokeh all first-rate... Of course it's 270mm equivalent focal on MFT. And a bit big for me. But a great bargain if yo...
