I doubt if a normal person could see the difference in a shot taken with the 50mm 1:1.2 , 1:1.4 or the 1:1.7 and I'm getting to learn how to use my 1:1.7A and I like it alot now.

How on earth would I have 11 1:1.2's If I had never seen one before?
Are you inventing some kind of new torture? You have 11 f/2's or 11 1:2's, but now you have seen and acquired your first 1.2 for 1:1.2, congratulations. It comes in A and K for your photographic pleasure.

I laughed my ass off when I read this. I admit, the 1.2 <---> 1:2 was quite maddening, it just wouldn't resolve. It's funny how everyone including me seemed to be hearing nails on a chalkboard over this.

Maybe it's because many of us have run across the common 50mm 1:2 several times in person, and there's always that split second where you can't tell for sure if it's a ":" or a ".", and you get your hopes up just for that second, and then you're always disappointed because it's just the same old stupid 1:2...

Thanks for the goose chase anyway, Wendy. Are you going to see Walter this weekend probably?

There really shouldn't be all this confusion since as I think we've established there are NO lenses marked just "1.2". To the best of my knowledge all Pentax lenses have the maximum aperture expressed as a ratio, IE 1:x or 1:x.y.

Anyway, a 50 f1.2 is about twice the size of a 50 f2 so you tend to realize quite quickly.

'Normal' person, Granted. Sean Carpenter isn't then I guess... [ Sean Carpenter's Photo Galleries at pbase.com ]
If you haven't seen this shoot-out of his, give it some time. It's a pretty comprehensive & impressive work. Of course incredibly subjective, focusing on bokeh quality a great deal, but point being once you put shots next to each other differences do become apparent.

I should add, and Wendy you'll love to hear this too, the SMC Pentax-A 1:1.2 50mm was the winner of the shoot-out of the 16 lenses that went up against each other. Much to your credit to quickly realize the outstanding quality this lens was rendering compared to the more typical A 1:2 lenses you were used to.

Thank You for having a level headed perception.

Exactly, as I so newly have found. I am sorry I upset everyone beacuse I noticed a lens marking and size that was different from what I have normally experienced throughout the last 30 years.

Perhaps,

Even though this forum already has been recognized as having one of the "best" databases of Pentax lenses and reviews available next to and above Stans.

Quite possibly we as a community need to widen the lens review database and recognize each individual Lens and the nuance's of each lens.

It may be as a whole we as a community of experienced "Pentaxian's"

Provide the best of "qualified" honest information and not opinion so that we as a community can honestly provide as guidelines for the new ones that try Pentax and have not any clue.

I have been around for quite a while but I will never hesitate and will take my time to honestly help and give an honest answer to a new Pentax SLR user.

It is a part of life and ones integrity.

Hi Wendy. I think the only problem here lies in the fact that you said this in your initial post:

"...lenses I have seen over the years have an "A 1.2" marking. "

The problem with this is that there are no Pentax lenses with an "A 1.2" marking.

This problem is further aggravated by the fact that you said you have 11 lenses with an "A 1.2" marking when it seems like you just confused the "1.2" with what it really is, which is a "1:2"

see here:


that's a ":" not a "."

I'm a newbie. I just bought my Pentax K100D 3 months ago and I only have one lens, which is the smc P-DA 40mm F2.8 Limited, so I respectfully defer to you in terms of experience and knowledge. Having said that, I also believe that you may have made a mistake somewhere. Whether it was an honest typing mistake or a mistake out of confusion, it was still a mistake that lead to the lengthy discussion on this thread.

Oh, and congratulations on the find. ^_^

I don't wish to offend anyone, but I am searching for the correct analogy.

This is like trying to describe an elephant to a person that has never seen one.

Pictures are wonderful - and save hundreds of words!

Here ya go - 2 very clear pictures of the infamous Pentax SMC 50 mm 1:1.2

I hope this helps!

There are 2 of these selling on Ebay at this very moment; one for a shade under $500 US and the other for over $700! The humble 50mm 1:2 lens, on the other hand, sells for under $50 on any given day. If she has 11 of the lenses pictured below she is sitting on a small fortune.

If I am not mistaken and of course I will be criticized again as usual. I was referring to the lens with the outside sloping bevel in my original post,

Pentax Lens Review Database - 50mm F1.2

I am and have been fully aware of the lens you are showing in your post. Eat your heart out I have and own two of them.

Plus you are more than welcome to stop by and view my collection as long as my husband is present.

Wendy, I think you have the Pentax-A version, with the "A" setting on the aperture ring. On the "A" setting, the camera body can control the lens aperture, which makes this lens very desirable for using with modern Pentax digital SLRs, as the auto-exposure modes will work.

And the version that J.Scott has displayed is the K 50/1.2 version (using Bojidar Dimitrov's naming convention, see K 50/1.2). The K 50/1.2 (or 1:1.2/50) is of course a fully manual lens, and the camera body is not able to control the aperture - the aperture must be pre-set to the correct value on the lens barrel.

So, Wendy, there are two versions of this lens, and it looks like you have both! They are both fine lenses and optically, very similar if not identical.

Well, thank you all, especially you Wendy B, for bringing this lens to my attention. I was vaughly aware of it from Bojidar's site but I did try to ignore it.
Now I want one.
My children have left home so they won't suffer. My wife has already left, so that is of little consequence. But why am I telling you this; you don't care, none of you care.
Why don't you just post a 'photo taken in low light, Wendy B, with this lens so I can see it. I will then bid uncontollably on e-bay & get it, probably to my financial ruin. (Where are the "Smiley's" on this forum?)

Jibbonpoint - that is a terribly sad tale. I don't have a low-light shot handy, but here is one that might comfort you, taken in the cloisters at the Australian War Memorial, and showing the delicate bokeh of the K 50/1.2. Take heart!
