FA*300F2.8 or A*300 F2.8?

I have a chance to buy either of these lens. Of-course Pentax FA* costs lot more,approximately $4950.00 for used , exc. condition. The A*300 F2.8 costs $2500.00...
FA has the AF but, since it is only 300mm I will be using a TC, most likely Tamron 2x.
A*300 will have the AF if used with F1.7 but a reach of 500mm .

Which one would you buy if had the choice?

Thank you for your input.

Harish

FWIW, a nice FA* 300/2.8 sold on ebay two months ago for $3100, which was the low bid.

Manual focus is not the way to go with extreme teles these days (the F converter won't make life easier). I recommend the FA*.

And hence why I'm waiting for the Sigma 120-300/2.8

I think that both lenses are to expensive. $1500 for A* and $3000 for FA* should be the max.

Granted, AF or MF may be a personal choice but IMO the F1.7x really does make the big MF glass easier to use when AF is needed for moving targets and thin DOF as with small birds at 6m. The built in limiter helps and the loss of IQ is very minimal in good light, unlike any 2x TC I have tried, including my 2x-L.
Although I often use the A*400/2.8 as MF for distant/still subjects, without the option of the F1.7x I would have put the lens out to market already.

Thanks! Does word really travel this fast, or are you watching the forum that closely?

Hi Harish,

I pretty much agree with Ron H that the lenses seem a bit pricey. I'd probably pay a bit more for the A*, but the FA* is probably about right for a lens in VG+ or better condition. I have an FA* 300/2.8 and the lens is outrageously good, but I held off until I could find one under 3K. The bodies got some scratches, but the glass is spotless. . .

Personally, I'd get the FA* again. It's a full pound lighter in weight, and the FA* is a handful, even compared to my Sigma EX 300/2.8 APO. The A* also has a min focusing distance of 3m opposed to the FA*'s 2m. This may not seem like much, but I find MFD a prime consideration in ultra tele lenses. The A* does have that choice aluminum case, but it'll actually probably get in the way more than be useful. . . I also assume that the A* will have a longer focus throw compared to the FA* -- while this may add precision to MF, it turns out to be a handicap when using the F 1.7x AFA.

These are my preferences. . . of course, YMMV. If I were to currently consider an MF lens in this class, I'd get a Tamron Adaptall 2 model 60B (I actually have one of these also). It's not quite the performer that the A* is, but at less than a third of the price being offered to you, I would put up with the PF in high contrast OOF areas at large apertures which is really about the only fault in the lens.

Scott
