Novice, basic lens questions?
[quote:3496ace15f="amilner"] The limited lenses are all prime (fixed focus lenses) [/quote ????? You have more chances of finding a fixed focus lens on a Kodak Instamatic than on a Limited lens. I think you mean fixed focal length. Not exactly the same thing.:shock:

Novice, basic lens questions?
I think at one point Pentax made a pan focal lens which was fixed focus, but not recently. Fixed focal length is what was meant I feel :)

Novice, basic lens questions?
A Pan Focus lens is usually one with the focusing fixed on the hyperfocal distance. There was a Pentax 110 18mm Pan Focus, but that's the only one I can recall.

Need help deciding !
For me (and of course this is always a personal choice) a starting point of 50mm is the very maximun I would consider for a walkabout lens. I am interested in nature shots if something interesting is happening for me to spot - I'm not a 'birdie' or anything - but I have taken a few interesting wi...

DA* 16 - 50 - sharpness issues?
Hi, Just wondering if someone could cast their eye over a couple of photos and tell me if I should be expecting sharper results. These are hand held shots. 36mm, f5.6, 1/45, ISO 400 50mm, f4.0, 1/250, ISO 400 They just look a little "muddy" to me. Sort of as if they are not in fo...

DA* 16 - 50 - sharpness issues?
Thanks, just ha a quick look at some of my old photos taken a few years back with a Nikon D70, and to be honest, the Pentax wipes the floor with them! Perhaps I am just being paranoid!! James

Pentax K manual focus 100mm f4 Macro: comments?
Hi all, I'm looking to buy a Pentax K 100mm f4 Macro manual focus lens. I think it goes to 1:2 (0.5 magnification). Any comments from experienced users?

Pentax K manual focus 100mm f4 Macro: comments?
They regularly appear on eBay. They are superb lenses and any of the versions will give good service. The A version will be more useful with DSLRs.

Pentax K manual focus 100mm f4 Macro: comments?
For the KX the SMC Pentax-M 100mm f4 Macro would be perfect and will cost less than an A version.

300/400 prime for MZ5N
Don't forget the manual focus ones that also iclude the 500mm, the 400-600mm zoom, the 250-600mm zoom....and so on. Lots of long lenses, some quite unique.

DA*50-135 and extension tubes
I'm seriously considering the DA*50-135... :D I've managed to hold back the LBA for a couple of years (with a minor blip for the DA17-70 on cash back :P ) but this one is burning a hole in my pocket... I have the smc F 100mm/2.8 macro. Of course it is astonishingly sharp and a joy to use. Howeve...

DA*50-135 and extension tubes
Right, just had a play. I have the Jessops Auto Tubes with all 7 contacts, put all 3 on, then the 50-135. The camera doesn't 'like' it, all the electrics go a bit funny! Couldn't change the flash to wireless mode because as soon as I hit the FN button the display flashes for half a second and ...

DA*50-135 and extension tubes
Had a quick go on tubes... it's a little odd. Firstly, you obviously have to switch to MF - either on the body or on the lens. If you don't then the "MF" indicator flashes like mad in the viewfinder. Aperture linking all works fine, and it's perfectly usable. Oddly though, there appears to be...

Tamron Adaptall 2 70-150mm f2.8 soft focus.?
Found one of used for £100 with postage and just wondered if anyone has/had one and if so what they think/thought of it. Thanks.

Tamron Adaptall 2 70-150mm f2.8 soft focus.?
Looks like an interesting concept, especially if you take lots of portraits. It also looks to be quite rare, so maybe £100 is OK. For an ordinary zoom of these focal lengths it would be very expensive. Do you already have a spare mount for it? That could add some serious expense.

Tamron Adaptall 2 70-150mm f2.8 soft focus.?
Yes I have a few of the PK/A mounts and normally only have one Adaptall 2 lenses in my bag at any time so not a problem. I can have it on 10 day approval so I think I may take a look. Thanks.

Tamron Adaptall 2 70-150mm f2.8 soft focus.?
Probably worth it because it's also a f/2.8 zoom. I don't know why but no one seems to use soft-focus with digital. With film nothing touched the Zeiss Softar filter. I've still got a 67mm diam. one that was made for the Contax camera. shim
