Telephoto Lens Suggestions

I currently have the DA 55-300/4-5.8, which is a great lens, but I'd like something with constant aperture throughout the range that's faster. The two options that I'm considering are the DA* 200/2.8 and DA* 300/4 or just the DA* 60-250/4. (Of course, I have assorted primes from the ultra-wide to short-telephoto range.) Which option would you choose? If it matters, I normally shoot between the ultra-wide to normal range. I only want something better in this range for long-distance photography such as shooting graduations or wildlife. Please let me know what you guys think!

Those basically are the current choices for a long Pentax lens that might have better IQ than the 55-300. You might also pick up some older M or A lenses which do not autofocus.

Right, but it comes down whether or not it's necessary to have two telephoto primes or just one telephoto zoom is sufficient? That's where I can't decide.

I have the A*200/2.8 which is excellent. I am guessing the DA*200/2.8 is of similar quality. The drawback is that 200mm is sometimes not enough. DA*60-250mm is very good even though reputed to be a little soft at 250mm. DA*300/4 is very competent. For some other alternatives Sigma 100-300/4 is considered to be very good and my Tamron 70-200/2.8 is a great performer.

I know what I would choose... Or at least, I think I do!

IQ wise = the two primes.

Oh but a zoom is quite versatile.

I think the zoom would be a better choice since this is a focal length you don't use a lot. I also don't use telephoto a lot so I bought a pair of legacy primes for less than $100. And one is very small so I can take it with and it isn't a big deal.

But why aren't 3rd party lenses options? They seem to meet you're criteria although I don't know what kind of IQ improvement they have over the 55-300.

I'm not very big on third-party lenses. I've used Tamron and Sigma lenses before, and the build quality, even in the high-end, is still lacking compared to Pentax's mid-level lenses.

I'm pretty firmly of the opinion that--unless you're very patient & stealthy--300mm is pretty much the minimum FL for wildlife (and, even that that, patience and stealth improve your chances significantly.)

Not only it will probably be more functional that two primes with how you shoot, but the 60-250 is a superb zoom.

Which Sigma lenses have you used? You should give the Sigma 100-300mm F4 some thought. It is just as good as the DA* 300 and it's a zoom. Built like a tank.

For the given purpose, the flexibility of a telezoom wins for me.

Alright, the DA* 60-250/4 it is. Can you use it without a tripod, handheld?

Sure! Just like any other long FL... Your shutter speed just has to be high enough in order to get a sharp photo.

From all the research I've done, that's is just a really bad question to ask. It's not about the lens, it's about the focal length. You can't hand hold any 300 mm lens and get as good results as you would on a tripod. If you don't believe me, I suggest you take your camera outdoors and give it a try. Even at 1000 of a second, there will probably be a noticeable difference in pixel comparisons. Hand held is for short focal lengths, and even then a tripod is probably better.

Nothing beats the privilege of owning an expensive lens with a short warranty combined with a high probability of having several SDM issues. Thanks, but I'll pass on that go with a more reliable 3rd party option backed up with a real warranty.
