Wanted to go shoot with the FA 50 yesterday after reading this thread, and had a moment of dread when I couldn't find my 50 anywhere - wondered if I somehow accidentally shipped it off to someone instead of some other lens, or if it had fallen out of my bag, etc.... Then I remembered that it's on my K100D, which I loaned to a guy. Whew.

Maybe I'll go out with the M 50 1.4 to tide me over...

truonganh, nice comparison & great observations. There is no doubt the 1.4 and 1.7 are both fantastic lenses. The 1.4 carries a bit more flexability in the depth of field as well as a tiny bit better low light capability, but man that 1.7 is an easy lens to love. Very few weaknesses. I'd like to see the FA or A series 1.7 stacked up in another fast 50 shootout some day. Come to think of it, the last shootout may have had a listing of the other contenders that didn't make the finals. I wonder if the 1.7 was among them....

Jay, you have a way of making a lens really sing. I look forward to your postings.

I've managed to obtain the FA 1.4 and an FA 1.7. I prefer the 1.7 and they aren't made any longer as far as I know. I also have sold many A series 1.7 lenses and have not had a single person mutter a hint of dissappointment. Everybody has been delighted with the 1.7. I prefer the A 1.7 over the A 1.4 as well. Just something sweet about that lens.

Just treated myself yesterday to purchasing a Ricoh 1.7 with auto aperture. Looking forward to getting it into my hands next week.

Back on topic, I'm gonna bust out the FA 1.4 and snap a few Florida shots for this thread - just for fun.

I have plan to push my FA 50 f/1.4 to the maximum use. I am not suggesting others to follow suite -- it is quite silly in my books.

Life is more fun when you have some goals and things to explore. It may be silly to some of you. Here is my cheapo quadruple lens plan and you are more than welcome to take a peek into my cheapo thinking and project


A quadruple lens with a single prime in FA 50 f/1.4 with 3 TC's

Twisted & LOL LBA plan
  • 1. A fast 50mm prime in f/1.4
  • 2. A fast AF 70mm f/2.0 prime with 1.4x TC
  • 3. A fast AF 85mm f/2.4 prime with 1.7x TC
  • 4. An 100mm f/2.8 1:1 Macro with 2x Macro TC with 'A' aperture and manual focus

And I have few test shot for the 100mm using the FA 50 f/1.4 with the Kenko 2x Macro Teleplus

So long as my shutter speeds are above the 50mm focal length, I find my FA 50 to be quite sharp at any aperture; even wide open . It's a fantastic lens and so very versatile when mounted. You might remember some lacrosse shots I posted a couple weeks ago that were taken with that particular lens:

RL deconvolution

[QUOTE=felix68;305285]I have found that some of the softness can be adjusted with the "RL Deconvolution" function in Raw Therapee. I think that Photoshop has this function as well.

I didn't know about this! thanks for the tip... Apparently this sort of image treatment is quite popular in astrophotography, for good reasons.

a little Googling and i found some cool stuff:
