K 55mm F1.8 soft?

Thank-you to everyone who replied to my initial post.

MysteryOnion and Johnyates;
I'm going to attach some examples to this post. The lens is free of definitely free of fungus.
It doesn't look hazy either, but I'm not an expert when it comes to haze.
What are some indications that the lens may be hazy?

JinDesu;
You may have a point about the coatings.
I'm not using a hood of any kind on this lens.
Most of my pictures with this lens are taken indoors.
Do you think it is worth trying a hood to block stray light indoors?

Just1MoreDave;
When I nail the focus, the lens is definitely sharper than the kit lens, but not a great deal sharper.
I hadn't noticed 'colour' fringing with the K 55mm, it's more like 'white' fringing if such a thing existed.

jt_cph_dk;
The crop you posted of a lens looks fairly sharp. I get the feeling it is sharper than I could accomplish with my lens.
Are the photos of the yellow rose cropped or a resize? Lens discussion aside, I really like the picture of the rose you took with the 55.
The subtle fringe you describe on the edge of you roses is hardly noticeable and not what is happening with my lens.

stevebrot and robbiec;
Great photos. Love the bokeh.
Although, on resized photos of that size, I don't think the soft halo/fringe would show itself if it had been there at the original size.

Attached to my post are images comparing my K55mm F1.8 with an M50mm F2 and an A50mm F1.7, each of the three at F2, F4 and F5.6.
Conditions were inside, under warm flourescent lighting, from about 3m distance, ISO 200, tripod mounted, remote shutter, using the camera to meter each exposure. I focused using the camera confirmation, and by focusing past the subject, then bringing the focus back towards me until I got the confirmation. I do this because I feel it gives me better results then if I focus towards the subject. The subject is a blue fridge magnet with white text.

Hi all,

The first prime I bought for my K200D was an SMC PENTAX K55mm F1.8 (bayonet) off eBay.

I had read great things about it and enjoyed shooting with it for a while, before becoming distracted by other lenses such as the M35mm F2 and the K200mm F4. Recently, I went back to using the 55mm and found I enjoy that focal length on APS-C, because it makes the image the right size in the viewfinder such that I can open the other eye and shoot at the same time as seeing stereoscopically. Additionally, taking photographs at 55mm seems to aid my composition - I like the way I choose to shoot with this lens and the look it gives my pictures. :D

That is until I decide to zoom in or crop. I've noticed when looking (too) closely at my pictures (including extensive home test shots) that this lens seems to lack contrast and sharpness around the finer details of the picture. There is a soft halo-ish fringe kind of effect over contrasted edges.

I acknowledge that these lenses are a challenge to manally focus, and I expect to miss the focus sometimes - but even under test conditions on a tripod, I seem to get the same effect. It happens at almost the whole range of F stops, but is more obvious when the lens is towards the wide end.

The same fuzziness does not present when shooting with the Takumar, A series or M series 50mm lenses that I have tried. :hmm:

My question for current or previous owners of the K55 F1.8
is this how the lens is supposed to be? ( or have I got a lemon? ) :(

Cheers,

Sd cards for k200d

I own the K200D. I bought it used.
My camera was unable to write to faster cards (2GB Sandisk Ultra SD) but it was able to write to normal cards (2GB Standard Sandisk SD).
Since I upgraded the firmware in my camera, it has been able to write to any of the cards that I've been able to try
My current card is an 8GB Sandisk Ultra SDHC 20Mb/s and it works fine.

The Pentax website says the firmware should fix problems with SDHC.

Latest K200D Firmware Update : Software Downloads | PENTAX RICOH IMAGING

Make sure you follow the instructions very carefully, ensuring to use good batteries with plenty of charge if you decide to upgrade the firmware.
It's very important for your camera that the process isn't interrupted before it is complete.
If you're unsure, ask someone with experience to help you.

All the best!

Greetings from Melbourne, Australia.

Been reading up on a lot of interesting topics on the PENTAX Forums without posting (until now).
There's some really helpful information (and advice) here for a learner like me.

Used to take all of my photos with a compact before discovering photography as a hobby about a year ago. Had lots of fun experimenting with my Dad's film SLR, but have decided the advantages of shooting in digital are too powerful to resist. Just picked up a used K200D in fairly good condition. Going to borrow Dad's lenses and work out which best suit my needs before I buy any myself.

Should have some photos to share in the not too distant future. :cool:

Cheers,
