Hi Roy,

The SP TCs are:

1.4x -- Model 140F -- I have this one, and it's excellent -- good enough that it's the one I use for stacking with the F1.7x AFA on the SP300. I'm casually looking for a deal on another one of these, but I'd probably pop for a decent deal on a Pentax A 1.4x-S or L first.

2x -- either the Model 01F or the rarer 200F. I have neither, but if find one at the right price, I might get one to play with. The only ones I've seen recently are the 01F, and they've been going for well over $100, so I passed. The 200F is better, but mostly in the area of better edge/corner sharpness. This advantage is pretty much taken away by the APS-C crop on our DSLRs, so I wouldn't be too quick to pay the premium this TC usually commands. I have an A 2x-S and a Vivitar 2x MFTC, and I rarely use either, so the SP 2x TCs are a low priority for me.

Of course, an F1.7x AFA is the perfect TC for this lens -- an AF 510mm f4.5 that makes me almost forget about even thinking about a Bigma. . . and then I can add the SP 1.4x TC and get an AF 714 f6.7. . . too cool!

scott,
thanks for the info.
i've got a 1.4x-s pentax. do you think it's better than the original tamron?? i know it works well on the 500/4.5 with little to no IQ loss. guess i may try it tomorrow. got to get well first tho. i'm really pumped about this lens since i haven't found a prob in IQ yet. i have lost some sleep over it lately. well , just a little.. the rest of the lens looks almost never used. even the tripod mount shows very little use..

I believe the 1.4x came as a set with this lens, I don't think the 01F was matched to anything, I believe it was the general adaptall 2x adaptor. When I got my 01F they were going for $30-$40 on ebay, are they really up to $100 now?

PS: I paid around $700 for this lens Roy. I am swearing out an affidavit against you for theft even as I type! :-)

Wow Roy,

I am impressed. You have hardly tested out your M42 300/4 before having this fast tele. I think it matches quite well with its TC 1.4 or 1.5x. I can only be green with envy as I cannot handle the weight. Look forward to some great tele shots

Hi Tim,

After a quick check, I was mistaken about this -- my normal confused state -- $30-40 is still the going rate for the 01F. . . The 140F is closer to $100, and while you can get A 2x-S TCs for under $100, the A 1.4x-S&L TCs are a lot more -- probably because they're more useable.

You are correct about the price he paid -- I paid about the same for mine -- an E+ from KEH. . . there has to be something illegal about this. . .

Well, if anything can get you feeling better, something like this should really do the trick! I can't decide if I'm envious or think you've lost your mind - I can't imagine trying to use a lens that big (just carrying it would do me in!). On the other hand, a year ago I thought I'd never own a 300mm lens because I wasn't steady enough, and I love my A*300.

Kjell - I think you are right about Roy's A*300. Being wiped with a brick is a pretty apt description of what the front element looked like in that picture he posted. On the other hand, he's also posted numerous excellent pictures taken with it.

just put a 1.4x-s on this and i can't close down to f2.8.
furthest it will go is f4. that's with the lens set to the A position.
why is this???

here's a couple with the 1.4x. full frame resize. this will focus down to just under 8 feet. the Df was probably 12'.. DOF is razor thin here.
