LBA - smc Pentax 55mm/f1.8

Hi all,

Just got myself a K55/1.8 from keh.com in EX condition. Ordered it on Friday last week and received it at work today (Thursday), so it took less than a week for it to arrive in Melb, Australia! How is that for fast service!!

Here is a couple of photos of the lens itself:

1. Taken with FA35


2. Taken with FA50


I have also bought something else with it and it came in in a case:

3. So what is it?


4. It is an auto extension tube!


I haven't have time to the extension tube yet but here are two photos I have taken of the extension tube with the new-to-me K55/1.8:

5. @ f1.8, on tripod


6. @ f2.8, on tripod


I don't know why this lens doesn't get mentioned much but it is pretty sharp wide-open and very sharp @ f2.8 already.

cheers
Kenny

Wow, kenny. This is in deed an excellant condition! To be honest, I was not even aware of a lens like this! (Shame on me)

Some test shots perhaps?

Hi James

Long time no see indeed!

I will do some test shots if the weather permits. As you know, the weather in Melb hasn't been that good (but welcomed since we really need the rain) recently.

Actually I have just been to another friend's wedding last weekend and took some photos. I used Tamron 28-75/2.8 99% of the time and I didn't bother to bring my external flash since I kind of got tired of processing heaps of photos every time I came back from friends' weddings! So this time I only took a little less than 100 shots so not too painful =)

cheers
Kenny

Afaik this was the "kit" lens that came with my KX (and K1000 ? ).
I just got an ME Super which has as 50/1.7 as kitlens.
So now I have two fast fifties.
Haven't done much with them yet on my K100D

Actually this is my 4th 50's already! Right now I have got K55/1.8, M50/1.7, FA50/1.4 and FA50/2.8. Used to own an A50/1.7 too but prefer the build quality of K/M lenses better so sold that to another forum member.

I have the m42 50 1.4 and the K55 1.8. They get about equal time on the DL2 for different reasons. For work I have to do lots of low light stuff and the 55 fills the bill for a short zoom with the 1.5 crop. Manual focus is cool due to the long throw. The word is that it really gets sharp after about 2.8 which for me is fine as that provdes the depth of field for groups of people.

This was a High School performance - used the 55 exclusively, from the front row no assisting flash..

The 1.4 is good for macros when I can take my time and use the bokeh to good effect.

Some test shots

Hi all,

I managed to grab some test shots on my way to get my lunch today. So here they are:

K55 @ f1.8


100% Centre crop of the above:


K55 @ f2.8


100% cetre crop of the above:


K55 @ f4


100% centre crop of the above:


I hope I haven't stuffed the f-stops since I didn't write them down while taking the photos.

As can be seen from the photos, performance isn't bad at all at f1.8 but very sharp by f2.8.

A couple of other shots:




cheers

Had this lens too:
The A 1.7/50 is (on my DS) simply better - more resolution, better flare-resistance - but the feel of the 1.8/55 is simply superb! Just more fun to use it.

But optically - on my DS..... perhaps with other cameras it's a little bit different but generally this should be true generally.

Hey, I'm new here so pardon my ignorance.
I have bought meself a K10D and I'm looking into option of buying couple of fixed lenses from the old Pentax ME. One of them is also 55mm 1.8 you lads are talking about here and I'm wondering if I'll have to buy an adapter or sth like that so that it will fit right on the camera? Are there any other problems with these lenses? What kind of program will I have to use on my Pentax? Fully manual?

Any help will be highly appreciated as I don't want to f*ck myself with buying something that wont work correctly on my camera. THANKs A LOT!

You won't need an adapter, but there are custom settings you have to use on the camera. I don't have a K10D, so I can't give you the exact settings. Try the FAQ section of the forum.
It works in M mode but in an Av mode sort of way: you set the aperture, push a button, the camera sets the shutter speed.

there are 2 versions of the 1.8/55:
The K-mounted and the m42-mounted.
I had the K-mounted for my comparison, my wife still has the M42-version for some dreamy portraits. Wide opened it's sort like that...
If you want the sharpest 50mm-lens you either have to pay for a 1.2/50 (over 200,-) or chose a 1.7-version which is a bit sharper wide opened than the 1.4 (which has the nicer/softer bokeh). Stopped down to 2.8/4 they're equally sharp - but the 1.4 still producing nicer bokeh.... and a better feeling/haptics.
