OK, y'all have convinced this Former Nikon Snob that the 50-200 kit lens is perfectly fine. However, I still have a problem. The husband is a bird photographer. We looked high and low for a decent Pentax mount lens with a focal length to 400 mm or more. Other than the Bigma, I can't seem to find anything. Tokina apparently used to make an 80-400 mm zoom, but doesn't now. Nothing in the Tamron or Sigma columns that I could see other than the Bigma. The 100-300 mm is not a long enough reach.

We can't afford primes, unless we're missing something. How is a 300 mm f/4 with teleconverters?

Is there some kind of Secret Pentax Users Club Journal with classifieds, or the Pentax Devotee's Guide to ebay? Yesterday there was a Tokina 80-400 mm zoom on ebay, but it turned out to have a Canon mount, although the notation said "for Pentax".

If Canon mount lenses can be used on Pentaxes, would that be with limited metering?

I really, really want to get a K100 and K1. But if we can't find a decent bird lens, it's back to the land of snobbery.

I apologize for my naïvété in advance. It's hard to find info on Pentax stuff, guys.

Hi fogueira and welcome to the forum. I appreciate your frustrations. Tele lenses of high quality are hard to find for Pentax. Pentax's current line up of lenses is strange to me. No 300mm f/4.5 lens made anymore. Makes you wonder what they're smoking at the head office. I recently contemplated switching to C or N just so I could get a faster tele lens, but my prayers were finally answered when I found a FA*300 4.5. Seems like there are lots of Canon 100-400L lenses and 300mm primes available for anyone wanting to shoot wildlife.
For Pentax teles, you really have to keep an eye on ebay or the used lens sellers such as keh (?), and jump when you see one. I looked for a long time before I could find the FA*300 4.5, and when I found it, I jumped at the opportunity. Great lens, and to answer your question about teleconvertors, I use the tamron 1.4, and it works pretty good. Images still come out sharp, but focus is a little slower, and you lose a stop of light. The offbrand lenses are good too if you get the right one. The Sigma Bigma is highly rated, and their APO 70-300 is a decent lens too. Also check out the Tamron 70-300. Nice cheap lens with pretty good image quality. If you want manual lenses, you can find a Pentax 400mm prime usually on ebay about once a week, and 300mm lenses too. Auto versions costs a lot more if you can find them....hope some of this helps.....cheers.......Don

The most affordable yet top quality prime as far as I know is M*300mm F4. The going rate in ebay is somewhere between $250- 450. It is reported as below that it is quite decent and handholdable when paired with a 1.7x Pentax TC.

http://forums.dpreview.com/forums/re...ssage=19527056
(performance wise, A* & M* are the same)

If you do not mind doing manual and older lens, there are a few older Takumar or Vitatar lens that should fit your need.

Pentax has not released any tele primes lately and we have to make do with the exisiting older stock which fortunately is quite abundant.

There is a newer and inexpensive FA J zoom 75-300mm that I have. It is less contrasty than the prime and soft unless stopped down to at least F8. Otherwise it is ok.

I just bought one of these, the SP line was their better lens, better than the BBAR.

eBay Item number: 250014731621

You can also look for Pentax takumar 500mm f/5.4 they appear quite a lot.

I was watching a M300mm* f4 lens on ebay last weekend that finished at $510US (sigh) - out of my price range (located in Canada, so it would have been convenient to me in Southern California). There are severalM 300mm/f4 lenses, not the green * so they aren't the top-of-the-line models, available for around $350US. I'm still on the fence as to whether I should get one of those two or wait until I can find (and have the money for) one of the green * models.

I have to say that lately the price of tele prime have gone nuts. All Pentax's fault as it is not releasing any new teleprime even in their roadmap.
Go back to the topic. Manual and older prime is the only way to go if price is an issue. And I do not think Canon or Nikon is offering any price break at all in that sector.

You don't need anything longer than a 300mm if you want to spend some time getting close to the birds you are photographing.

This one is in the States and there is a star there with minor imperfection but not in the optical sense. All M300mmF4 has *.

There is a 300mm lens that is not a * lens, actually more than one if you include the M42 screw mount lenses.

300 mm f/2.8 A*
300 mm f/2.8 FA* ED (IF)
300 mm f/4.0
300 mm f/4.0 M*
300 mm f/4.0 A*
300 mm f/4.5 F* ED (IF)
300 mm f/4.5 FA* ED (IF)

Tom,

Another one of those birdie pict that renders you speechless. Ok. All you need is a mid tele and you have to be on top of a 10 ft ladder. And a rare bird is to fly over and freeze there. Tom. You are unreal.
