Re: 50mm lenses. ....Re: LX vs K2dmd vs Super Program (update)
I agree Rob. I dont own the 1.2 but have found that A50/1.4 and A50/1.7 are very different lenses in terms of image renditio as well as sharpness. A50/1.7 is a fine, very sharp lens at most apetures but seems to lack the 3-D quality of the A50/1.4. For me it is almost as if the A50/1.7 is TOO sharp for most uses. I dont know , the images just seem a bit flatter with the 1.7. Sharp but flat. Wheras the 1.4 produces very nicely rendered and deep images (if that is possible). Would love to see some pictures taken with A50/1.2 to compare. A.

Re: 50mm lenses. ....Re: LX vs K2dmd vs Super Program (update)
Fred, for me there is more goinging on between the diffent 50's than resolution alone. For me (and this is just an opinion here) resolution is just an indication of whether a lens is gonnna be a poor performer or not. I.e. Just something to check isnt too bad. But the real qualities of a lens, i.e. The ones that are going to affect the image most are colour and image rendition. Like penis size, resolution can be completely misleading as to real world performance. Antonio.

50mm lenses. ....Re: LX vs K2dmd vs Super Program (update)
- Original Message - From: [EMAIL PROTECTED] Subject: Re: LX vs K2dmd vs Super Program (update) Well, when I actually TESTED my 50s I found that the M 50/2 is a really good performer, plus it's cheap and very small. None of the above can be said for A 50/1.2 from what I've heard (I sold mine a while back, before I had a chance to test it.) The A 50mm f/1.2 is pretty soft wide open (though much better than the Nikkor 50mm f/1.2 that I replaced with the Pentax lens), and is only ok until about f/8, at which point it is very good indeed. So, while you might pick up a faster Pentax 50 which is a LITTLE better (I'd suggest A/1.4 or A/1.7--at least the M50/1.4 is an older design and reputedly not as good) I don't think you'll be disappointed by the A 50/2 (assuming it is the same as M50/2) and I'd recommend putting money towards a better telephoto or wider wide if you find the need for that. All the Pentax 50mm lenses in the f/1.4 to f/2 range are good lenses (perhaps the K55mm f/1.8 is the exception, it isn't all that wonderful until well stopped down). Of all the ones I have, I think the K 50mm f/1.4 is the sharpest, the M 50mm f/1.4 is the creamiest (for lack of a better term), the FA 50mm f/1.4 seems most excellent, but I haven't shot a lot with it yet, and the 1.7s and f/2s in whatever series all seem very good as well. I don't have many samples of each, but I have almost a dozen 50mm lenses in various places around the house, so I have been able to test (as much as I test anything) more than one sample of most emulations.

Re: LX vs K2dmd vs Super Program (update)
I'm guessing the only difference is the newer styling and A setting on the A lens. There's a coating difference, it would seem, too. Fred

A while back I was asking about comparisons with these 3 cameras, I thought I'd let y'all know how things have turned out. I recently purchased an LX on ebay, and will hopefully pick it up this weekend. Now to improve my selection of glass... I now have 3 bodies and 4 lenses. :) * LX * K1000 A3000 A50/2 M135/3.5 Vivitar 24-48/3.8 Sears 80-200/4 __ Do you Yahoo!? New and Improved Yahoo!

Re: LX vs K2dmd vs Super Program (update)
Wow, you're going expensive with the LX ;) Excellent camera. After some research into my first SLR and a short 'test drive' on a borrowed K1000, I ended up with a P30t, and an MX. Although I got my mom a K1000 as her first SLR, just to keep things interchangeable within the family. Maybe more later. I tend to end up collecting things, and it's been a while since the last collection of stuff. Not to mention that so far I'm enjoying the whole photography experience - I can't wait to join my school's photography club in the fall, and get access to the darkroom to do my own BW developing! Something to do other then go to school to mechanical and aeronautical engineering is always appreciated. Hope you enjoy your cameras! -Andrew On Mon, 9 Aug 2004 20:52:49 -0700 (PDT), Jon M [EMAIL PROTECTED] wrote: A while back I was asking about comparisons with these 3 cameras, I thought I'd let y'all know how things have turned out.
