The funny thing is, I fixed it before coming back here to tell you about it, only to see your last post about the ball :D.
I did notice when I was pulling it apart that a ball bearing that had fallen out, but i couldn't figure out where it came from. After my last post I had a break and then decided to give it one last look. It took me a while to figure out where it was supposed to go, but I found it, and now my aperture ring clicks again! Thanks heaps again for your help Elliot.
Cheers,
Daniel

Thanks heaps Elliott for pointing me in the right direction. My lens now focuses great :D it was slightly different for my lens, there was a stopper screw which could not be adjusted but the pieces were held in place with tape. I focused on infinity, removed the tape, adjusted the focus until a far-away object was in focus, then replaced the tape.
I only wish I read your post before I tried it myself... I opened up the lens from the back to see whether I could figure it out, and now the aperture ring doesn't "click"... It still works though. Not a huge deal but it was fun seeing how it works lol.
Cheers,
Daniel

Is this possible for me to attempt myself? It's only a cheap lens and I have a Pentax-A28 2.8 on the way, but I'd love to give this a go as the lens will be a throw-away if I can't fix it anyway.
Cheers,
Daniel

Sorry forgot to mention, this is on a K-5 in manual mode with ISO 100.

Hi guys,
I want to start doing some street photography and have an old Quantaray manual 28mm lens. I'm trying to zone focus with f/8 and f/16 and at close distances (eg. 1m, 2m) the pictures are sharp. But if I focus to 2m or infinity or anywhere in between, far away objects are blurry.
I even tried using catch-in focus to see whether focus locks when it gets to infinity, but it doesn't. The trigger never fires. I'm doing catch-in focus right, because it works on close objects, the trigger fires when the object is in focus.
Do you think this lens is faulty? It doesn't seem to be able to focus on far-away objects. Even at f/16, with the lens focused at infinity, far-away objects are blurry.
Or (hopefully) I'm doing something wrong and can do something differently to get sharper photos?
Thanks,
Daniel

Hi,
Sorry to dig up such an old thread! I just want to make sure I understand this correctly. I've got a Pentax K-5. If I bought a Nikon flash that has TTL, and a set of RadioPoppers JrX, then I could use the Nikon flash, with my Pentax camera, in manual mode, and I could control the flash power levels remotely?
TIA,
Daniel

I just got a new K-5 and am using it in TAV mode, when looking through the viewfinder and at the top LCD, the zero character only displays the bottom half. I'm not sure how to explain this properly, but a digit on an LCD calculator is made up of 7 lines, the number 8 uses all 7 lines, and I would have thought a number 0 uses the six lines around the edge, but it only seems to use the four lines at the bottom... Does this make sense?
The strange thing is this happens for eg 128000, 32000, 51200, but 4000, 5000, 6400, look fine, and use the whole height for the number 0...
Eg it will look kind of like is: 128ooo, 32ooo, 512ooo, 4OOO, 5OOO, 64OO
I hope I've explained this well.
Anyway is this normal or do I have a defective camera?
Thanks :)

Hi guys,
I'm looking to buy a new K-5, wondering if anyone's seen any good deals from online Australian stores that are reputable? I found it for $840 including shipping at dwidigitalcameras.com.au but wondered if there's a better deal to be had somewhere else.
Thanks heaps,
Daniel

On my Tamron 28-75 f/2.8 macro, the markers for focusing go from 0.33m to 3m, and then to infinity, with nothing in between.
I have a DoF calculator on my ad which says that when the lens is at 28mm with aperture f/8, if I focus at 3m then 0.30m in front and 0.38m behind will be in focus, but if I focus at infinity then 26.87m in front will be in focus...
So the DoF calculator says that for 28mm on f/8 the hyperfocal distance is 26.87m but my only choices are 3m and infinity... So if I set it to 3m then I'm only getting the area from 2.7-3.18m in focus, and if I'm focused at infinity then I'm only getting the horizon and 26.87m in front of it?
Also, if I'm using autofocus, when I'm focusing on anything further than 3m, will the focal point it chooses be considered "infinity"? When I focus on different things, all more than 5m away, the focus does shift *very* slightly... I thought it should stay the same?

Looks much better with the plane removed. But I actually liked it better with the black space at the bottom, looked more balanced to me. But I'm very new o photography so I could be in the minority with my opinion.

Great picture, I love it. The colour in pictures like this is what attracts me and what I want to create myself. How did you get the sky to look like that? Was it just the HDR or some other PP method? Or did it really look like that?

Is it possible for one 50mm f2.8 to be faster than another 50mm f2.8 because the size of the front glass increases the intensity of light delivered to the sensor?

So the aperture relates to the size of the opening created by the blades, not by the size of the glass?
And a "fast lens" is called a fast lens because it has a larger maximum aperture opening (smallest possible f number), and doesn't have anything to do with the amount of glass, the quality of the glass, or the lens design?
This is how I understood it but my friend thinks that a "fast lens" is fast because it has more glass.

A friend and I were having a discussion on aperture and we couldn't seem to reach an agreement.
He says that a fast lens with a larger aperture just means that it has more glass, and I argued that a fast lens means it has a larger hole created by the blades, which does have a relationship to the glass size, eg. my fa50 1.4 doesn't have enough glass to open up to 1.2.
But he said that different lenses could have the same aperture with different size glass, eg his 1.4 could be bigger than mine, and therefore faster...
I think he's wrong but he brought up a good point - an iPhone has a 2.4 aperture but its much smaller than 2.4 on my DSLR... How is that possible?
Thanks,
Daniel

Sorry to highjack your thread but I just had to say THANKS so much for this post! I'm new to photography and have done LOTS of reading but never came across the concept of diffraction. All the tutorials and books seem to suggest simply that "smaller aperture will result in more of your image being in focus" - I've been wondering why my lenses are so soft, and this could be the answer. I can't wait to fire off some shots at f5.6 and see how much sharper they are.
While researching diffraction it's been like a light bulb was went off in my head. I found this link really good: http://dpnow.com/7644.html
BTW I'm on a k200d with an fa50 1.4 and a Tamron 28-75 2.8.

Cool, sounds like something I should look into. So is an aftermarket focusing screen an easy / inexpensive upgrade?

Thanks, that's what I thought, glad you could confirm.
I always shoot in Manual anyway, and usually prefer to manually focus too, the auto-focus never seems to do exactly what I want. But I've never heard of a focusing screen - what's that do?

Hi guys,
I bought a used Pentax K200D as my first DSLR (previously only owned point and shoot cameras) which came with an 18-50mm zoom lens and a 100-200mm.
I bought this lens: eBay Australia: Buy new & used fashion, electronics & home d?r (Quantaray 1:2.8 28mm Prime wide angle lens Pentax K mount)
It's paid for and on it's way but I just noticed in the description they say "This lens is fit for all P/K mount 35mm Manual Pentax SLR film cameras" ... Will it even work on my DSLR? Or have I bought something useless?
Thanks so much,
Daniel
