50mm with Macro TC

I'm going to be using a 50mm lens with a macro TC (auto version)

I plan to also use this lens with my K-X and my K1000 with or without the TC

I don't plan on spending more than $200 though.

I would like some pretty good/decent looking bokeh ;D.

I need something that can be sharp too.

Anything under 2 so... 1.7/1.4.

Some lenses that I have in mind are... FA 50mm f1.4 (not sure if the AF would work in the TC) and some M and A lenses.

I would prefer to stick to Pentax.

You should probably note which TC it is. There are many available for the K mount (used of course). The TC is the Vivitar 2x Macro focusing, PK/A. No, this TC will not autofocus so if your desire in buying an FA lens to use with it, it will be like spinning tires on a grease slick. The TC will allow you to do auto everything else though so you can use Aperture priority (with an A or later lens). That isn't to say that an FA50 wouldn't be a good lens to have but for a TC, the autofocus is a waste of money. It was my experience that the best performers on this particular type of TC was the A50 f1.4 though the 1.7 is no slouch.

You may find that AF is wasted in macro work. Since you say you want a 50mm prime, I assume you'll be shooting in a studio, where hopefully your eensy weensy subjects won't run off. (50mm is a bit short for most field work.) Macro shots have razor-thin DOF anyway, and you'll want to focus carefully, manually. Using a non-AF TC will disable matrix focusing and focal point selection, so focus confirmation only works at the center point. Bother. I think you'll find that many folks doing 50mm macro work use the cheap, brilliant Industar-50 f/3.5 on M42 tubes, and spend a lot less than your budget. Like, the high end on lens plus tubes is maybe US$50. Have fun.

Yeah I was thinking of an A50 F1.4 or 1.7. FA 50 would still work though right? (dumb question... but can you manual focus a FA 50? I was considering the M line as well. Yeah I'm just basically looking for some okay fast 50mm okay bokeh lens. Where the doubled function would be being able to be used as a macro on the Vivitar 2x Macro TC PK/A. Everyone needs a good 50mm ;D!

Hmm... with the Vivitar 2x Macro TC PK/A wouldn't it turn a 50mm lens into a 100mm macro? (sorry I didn't specify). I wouldn't use AF much in macro anyways, I don't need it, but it would be fun to have. As a normal 50mm lens though, it wouldn't help to have one. Eh, ;( I already bought the TC... so I don't think I will be switching to tubes anytime soon. Yeah I would save my money. I am looking for a fast 50mm lens while I'm at it though so I'm going to spend a bit.

Thanks for the info though, maybe I'll consider this in the future

Yeah, I never knew that a 50mm macro would most likely be used in a studio. Bugs are afraid of me ;(.

Yes, you can manual focus the FA lenses. I Personally do not care for them however (except for the LTD lenses) because the throw of the focus ring is so short. The focus ring/mechanism doesn't feel very nice to me either. That's a pretty nit-picky thing to say about them but it's why I've sold every one I've ever owned. Many here will likely disagree with me on that.

Yeah... I do prefer the A and M styled Focus... even though I've never tried a FA focus. I guess if I were to get a FA might as well get a DA (though it has no backwards compatibility).

Hmm... A 1.4 or 1.7.... that is the question. (maybe Ms?)

I love my 50 and 100mm M series f4 macro. Here's a couple examples of what it could do.

1:1, i think with 50mm of extension tubes


1:2 with no extension tubes, bird was less than arms length

I got lucky by getting the 100mm lens for $100, 50mm for $63. Extension tubes for $30.

also here's my M series 50mm f4 macro, handheld


hope this helps
