Originally posted by Andi Lo IIRC Takumar-A is one of the 'budget' pentax lenses without the SMC coating. It's still worth it at 12.5.
The Takumar A was one of my very first lenses. It wasn't particularly great but it wasn't a doorstop either. I used it for a few months with my K10d before recycling it for something else. I thought it made a decent portrait lens and on that camera I could get decent prints up to about 12x18 (inches) with it. It also has closeup capability IIRC if you want to play with that. Definitely worth the piece price based on the entire lot.
To Marea,
I know from the other thread that the 50 f1.7 is en route from our friend up north. It will simply blow away the 50 f2.0. The latter isn't a terrible lens (again) but the f1.7 is simply better. That and the Tak-A are the only lenses on that list I have any experience with. If you already have the kit lens and are getting the 50 f1.7, I'm going against the grain here and saying pass on the lot. That is, unless you want to play with the film camera. Then, yes, as a lot it's probably worth the price.
That said, if you go for it, Bags also cost money. Your K-x with a short zoom will probably fit in that Tan holster bag for instance. I would be careful (with out knowing more about it) using that flash on my camera. Before doing so, check with us so we can help you determine if it's safe. Before mounting any of the other third party lenses to your K-x, again, check with us. Some third party lenses are made to also work with Ricoh cameras. We want to make sure that these are not in that category. I would hate to see you get a lens stuck (literally) on your brand new camera.
On the zoom lenses, have your friend check for Zoom Creep. Particularly on the third party lenses. A lot of these lenses will not hold their zoom positions at all when tilted if they are push pull types (the Tak-A is not). If they do not, then they are useless for anything but level line of sight shooting. The 2x converter, a lot of us make extension tubes out of them by removing the glass. It's easier to do on some than others but I remain convinced that for most of them, that's all they are good for.
Those of course are just my opinions and what to watch out for on Any used lens and flash purchases. Take it for whatever you think it's worth.
