Pentax 50mm f/1.7 vs Pentax 50mm f/1.8 image quality?

Hi, I am getting into buying new lenses lately, so I have been shopping around for a high image quality 50mm lens. When I asked a sales representative at a store, they suggested to me the older (and rarer) 50mm f/1.7 and the 50mm f/1.8. They are cheap lenses with high image quality.

So my question is this: if anyone here has tried these lenses, what would you say has the highest image quality? (Sharpness, color reproduction, contrast, bokeh, etc.) Any opinions and PHOTO EXAMPLES especially will be a fantastic help

Are you talking about the DA 50mm F1.8? If so, you can expect it to do better in terms of aberration and flare control, but the sharpness should be about the same (a good fifty isn't hard to make, after all) and the build quality is, well...crap in comparison to the older and cheaper lens. Might not hurt to get both given how little you can get the M lens for!

Both lenses are decent optically, the biggest question is whether having AF or not is important to you - just pick a 50 and go with it - as an owner of 180 50mm lenses, I know what i'm talking about.

Old 50's aren't that expensive, if you really want a lens you'll love I'd pick up an assortment, take 'em all for a test drive, and then re-sell the ones I don't want to keep. There are multiple components to image quality - sharpness, color rendering, bokeh, etc... so it's hard to say up front which one is best for your particular tastes.

Look at the lens reviews to build your list of "usual suspects", it's basically going to consist of old Takumars, Pentax-K, Pentax-M, Pentax-A, etc...

All this is assuming you're OK with manual focus, as that's what all these older lenses will be.

Also, there are some good "near 50" lenses, so I wouldn't rule out 55's or 58's like the Helios 44.

Acquisition (apparently) is the name of the game

yeah that is actually how I got started with 50's too, I sell the duplicate lenses I find. Though many of the 50mm lenses I have acquired in the past decade have been specifically bought to add to the collection.

As a recent K-30 owner. Gear lust got the best of me and made some impulse buys on eBay, B&H and Adorama.

Regarding this discussion. After sifting through forum threads and looking at samples. I got the following 50s:

1. Pentax Super-Takumar 50mm f/1.4 Lens (M42 to K mount adapter required) - This covered my f/1.4 requirement. Since wide aperture lenses are challenging to focus, I opted for the cheaper vintage manual. My poor vision doesn't help, but live view does. FYI, Lens element not recessed, hood recommended.

2. SMC Pentax-FA 50mm f/1.7 - This auto focus FA50 is for events, where I can enjoy myself and quickly capture some moments with auto focus. Lens element is recessed. Hood preferred for safety and image quality.

Related accessories:

1. Pentax 49mm Rubber Lens Hood (round) for 50mm FA, F & A-Lenses - PELH50Q - Works great with my Super-Tak.
2. General brand reverse adapter for mounting lenses with 49mm Filter Threads Backwards on Pentax K-Mount Bodies - GBRRP49 - Can now do macro on the cheap with the 50s.
