Lens for low light,Dark scenes
For low light and without additional lighting you need either a faster lens or higher ISO, or both. K or A50/1.2 (manual focus), FA50/1.4, DA*16-50/2.8, DA*50-135/2.8 are perhaps your best options. Same as mannesty F2.8 or faster would be your best :)

Lens for low light,Dark scenes
i'm with MattMatic. original poster seems to have gone awol here but to advise we'd need to know what you are trying to do, and what your budget is. I am very glad I got the 1.4 50mm auto from SRS when I got my K10D. It is a fantastic lens for indoor flash free portraits. I've also used it in co...

Wobbly 16-45 Focus Ring
I would like to ask if other users of the Pentax 16-45 experience a slight wobble/knock of the focus ring. I've just received the lens from SRS (who have been very helpful during my recent initial purchases with them), and whilst the image quality is fine, I'm a bit disappointed about the slackn...

Wobbly 16-45 Focus Ring
It's hard to say, because modern AF lenses are very loose compared with manual focus ones. The only way to be sure is to compare it with another sample, so maybe someone within range of you could meet up for coffee and have a look at two lenses side by side?

Wobbly 16-45 Focus Ring
Well I think this is the first time I've held lenses to my ears and shook them. My 16-45 behaves as you describe but nowhere as noisy as the 18-55! Stop being intolerant.

Wobbly 16-45 Focus Ring
Just tried mine and it also does the same thing. Never noticed before now .. so it's REALLY going to annoy me next time I use it. Thanks for bringing it to my attention ... :D Seriously though, never been an issue before I noticed so it won't be now.

Pentax 18 - 250 or Fuji S100FS
Surely when the lights gets darker the noise of the Fuji will be a lot more compared to the Pentax. Also since you can up the iso higher the shutterspeed goes down which means sharper photos. Photozone still finds it a good lens in this range, they said "the DA 18-250 is a worthy representative o...

Pentax 18 - 250 or Fuji S100FS
Whilst I like Fuji and had a S9500 a while back, I'm inclined to say stick with your DSLR. I doubt that the 18 - 250 is any worse than the fixed zoom lens on the Fuji. And just think of the superior performance with more specialised lenses you can buy, not to mention the sensor advantage with your K...

Anyone using the old SMC-M 40mm f2.8 on a K20D?
Hi, Any users here of the K20D with the old M series 40mm pancake? Just wondered, what results do you get, how easy is it to focus and do you get fed up with stop down metering? cheers Steve.M.

Pentax 16 -45 or Sigma 17 -70 or Tamron 17 - 50
So much choice can be confusuing, but if you can pay the price of the Pentax lenses they are worth it. Don't forget that the SMC coating gives superb consistence if colour from lens to lens as well as resistance to flare. The controls all work the same way, such as direction of zoom, the ability ...

Pentax 16 -45 or Sigma 17 -70 or Tamron 17 - 50
I personally went through two copies of the 16-45mm, the first had substantial wobble on the extension as if something was broken inside, I sent it back and got a replacement thinking that it must have been damaged in transit - the second had extremely soft corners which didnt sharpen up until f/11 ...

Can this be repaired?
:shock:Is it the same lens? have you checked the serial number etc, you wont be the first to refund the money and when it arrives back it's totaly different, they get the lens and money back.:P

Can this be repaired?
I didn't even think of recording the serial number! I'm too trusting! No, I think most likely it's the same lens, but I am puzzled as to what happened. Could the part have just shaken loose in transit? I've not received it back yet. Those are the buyer's photos. Mine would have been in focus ;)

Can this be repaired?
Looks like the retaining ring on the rearmost element has become unscrewed - should be simple enough to screw it back on. Rather than trying to disassemble the lens see if you can do it in situ: Use tweezers to reseat the ring over the threads and use something like a pencil eraser to screw it do...

Can this be repaired?
Thanks again Hefty1 for your tips. I've now received the lens back and have relocated the part with fingers and a pencil rubber. I couldn't tighten it much though, so I fear it may come loose again. Anyway I'm gonna stick it on eBay tonight at 99p start price. I'll also accept a direct offer o...

which one to choose DA* 55 or FA 43 limited
I have the DA*55 but not the FA43 Limitied. Opticaly I think the DA*55 is a very good lens - I did a 'first impressions' of it in Since then I have used it a bit and find that focus in good light is just as good as other SDM lenses. As its a nine blade aperture the out of focus highlights ar...

which one to choose DA* 55 or FA 43 limited
Here just to ease your mind a bit If you've the DA*55 there isn't much reason in terms of image quality to get the FA43 also. Do you have focus problems btw with the DA*55 on the K10D, it seems to be a problem :(
