Pentax smc A 50mmm 1.7 - is it a good deal?

Hi.

I am interested in buying a prime. Older, Cheaper, Good. I found a Pentax smc A 50mmm 1.7m, read the reviews and it seems a logical choice (to be used in a K3). I am trying to buy it for 50 (around US$68). Is this a good deal? Can I use it afterwards with the Catch in focus mode? My idea is on one hand to develop photo technique and on the other a general lens with a more "close to the eye" view.
What would be your recommendation?

Thanks.

I think it's a good deal.
You can use it with Catch-in-Focus. In Av, with CiF, it'll be almost like an AF lens, except you are the lens' motor.

It's a fair price, but not a steal. Here's a link to the members' reviews of that lens. SMC Pentax-A 50mm F1.7 Reviews - A Prime Lenses - Pentax Lens Reviews & Lens Database

Looks like the average price was about $64, so you're right in that ballpark. I have a couple of copies of the M version of this lens and I love it. If you're wanting a prime and this is in the focal length range you want, I'd buy it. Great lens...fair price.

I think it's a good price for being in Europe. Everything tends to be a bit more expensive here than west of the Atlantic.

However, as for "close to the eye" - 50 mm is a bit longer than than on a K-3, more a short tele lens. I would look for something in the 28-35 mm for a "normal" lens on APS.

as said above, a lovely lens and quite sharp.

$70au seems to be the going rate for my area, so the price seems fine.

It's good value anyway, the next step up is the F1.4 which seems to sell for about $200, so the F1,7 really represents the best bang for your buck (bang for your Euro doesn;t have the same ring to it)

An excellent lens. It's only 1/3 slower than the much coveted f1.4 and I don't think the price difference is really worth it. Supposedly this lens has a rather free from barrel and pin-cushion distortion which makes it a nice macro lens when used with tubes or bellows.

Note that the spring clips often need repair. This is a fairly simple repair if you have the tools and the dexterity and patience to carry it off. Re-assembly of the lens can be challenging though.

Depends on if you consider the nicer bokeh rendered by the 8 blades of the 1.4 worth it.

I just bought one on Ebay for $55 USD (plus $10 for shipping). The other one that I was watching sold the next day for $52 I believe.

Being a newbie at pentax is crazy...... what a wonderful world...

Thanks guys.

After the comment from "Not A Number" I just dig a bit further in and found a smc M 50 1.7. It is attached to a a ME Super with a kenko 2x kax macro teleplus mc7 and has on the side a smc M 1.4 75-150. Forget the camera. What about the lenses? it comes at around 95US$. Buy or not?

Yes and yes. I mean, its a good deal if its in good condition. But A 50mm often go for a higher price.

Mmh, not sure if 50mm is perfect for this, maybe something wider. On crop sensor, 50mm is a little tele. But the 50mm f1.7 is a great lens, I highly recommend it. The M 50mm f1.7 is usually slightly cheaper, optically just as good, but without automatic aperture.

Here is a great resource of member reviews:
https://www.pentaxforums.com/lensreviews/
Just scroll down to M series and check those lenses. I have a M 50mm f1.7, bought it for a little over 50 (+shipping) and am glad I did. Good lens, especially, as you said, for learning with manual primes

Go for the A if you can. The M is better made but you'll soon get fed up with having to meter manually every time.

I agree, between M and A 50mm f1.7, the A series is much more convenient.

That's way too much for the lens itself! The "kenko 2x kax macro teleplus mc7" is very useful if you don't have a macro lens: Hin's Photo Corner: Kenko 2x Macro Teleplus MC7 Adapter
The M50/1.7 is very similar optically to the A50/1.7 but it lacks the "A" setting on the Aperture ring so you'd have to use stop-down metering with the green button (annoying to use and more annoying if you forget to do it).
Without knowing where in the Eurozone you are, I can't tell what prices to expect but based on german ebay prices, 50 is a good price but not a huge bargain: pentax a 50 1.7 | eBay

Another good source for used prices is this: Foto Pentax ebay - a set on Flickr, it's not quite up-to-date but things haven't changed too much.

A50/1.7:


M50/1.7:



The A50/1.7 is a nice lens to try out the focal length, if you like it you can get a DA50/1.8 at ~130-150 new or ~100-120 used.

On the other hand, the DA50/1.7 has dropped to quite good prices (130-150 new, 100-120 used) and if you like the FL, you might find yourself wanting AF quite soon.
