DA* 50-135mm or DA* 60-250mm

The DA*50-135 or the DA* 60-250mm?

I already have FA50mm 1.4. Is the IQ of the 50-135 far superior or do you just get an extra two stops? I know the 60-250mm is 1.5 times the price but is this a better valued lens with the almost twice the reach. How do the two handle? is the 50-135 alot more usable in the hands? I want to buy a DA* but i think for the moment my DA 18-55mm AL II kit lens will cover the DA* 16-50mm at this stage.

How often do you shoot over 135? And if you do always do so why not consider sigma or tamron 70-200 F2.8??

Do you need the reach or the extra stop? I think this depends on your planned usage of the lens. For example, if you are taking photos of some indoor events, kids basketball for example, 50-135mm would probably be better. Yet if you are more a bird shooter, the extra reach of 60-250mm would serve you fine.

I only have 50-135mm and are quite satisfied with it. Let me just say it's the smallest f2.8 zoom I've used. Size and weight are actually important criteria for me.

I don't shoot over 135mm at all because i don't have any glass that is that long. It's the weather sealing that makes me want DA* lenses. But both the sigma 70-200mm 2.8 and the tamron look like great lenses.

It's worth it. The 50-135 at 50mm is absolutely sharp. I have had the pleasure of owning both; I sold the 501.4 after a week of having the 50-135; just no need to have two incredible lenses with the same focal range.

F1.4 is 2 stops faster than 2.8 do not forget about this

I owned the 50-135mm but having played with the 60-250mm recently, I would pick this lens because of the more versatile focal range and because it is sharp wide open. With one 60-250mm, one can probably forego the DA* 50-135mm, 200mm and 300mm lenses.

True, but the constant aperture of the 50-135 gives you a fast lens at more focal length. Well worth it (to me, at least) to trade the two stops and not need a 50mm prime in my bag.

Except the 50-135mm and 200mm are also sharp wide open, which is one stop faster than the 60-250mm. This is what's bothering me. I would like the extra reach, but not at the cost of speed. The Sigma and Tamron lenses are not weather-sealed, so they are not an option for me. Pentax should make a weather-sealed 70-200 f/2.8, they could probably make it smaller than the Sigma and Tamron offerings because it would be optimized for APS-C. That's extremely unlikely to happen, though, because it would compete with three other DA* lenses in their lineup...

.
Depends on the usage, I have the 50-135 and use it extensively ...great lens and I wouldn't be with out it. I think overall a more useful lens than the 60-250 and smaller ... but if you need the extra focal length, get the later.

For me I would rather have the 50-135 and then a couple of longer primes. But I can certainly see situations where the 60-250 would be very useful. Oh heck, get em all!

I passed on the 50-135, with the intent of waiting for the 60-250. The extra stop of speed that the 50-135 gives would have been nice, and I agree with Mike that overall it is probably the more useful lens, but I wanted the reach of the 60-250.
They are both very good lenses.
The advantage of the 50-135 is size. It is a compact, easy to handle lens. The 60-250 is anything but compact. It is big and heavy and a bit awkward in the hand, but is a pleasure to use on a tripod.
The advantage of the 60-250 is the reach. There is a big difference in reach from 135mm to 250mm.
I think the 50-135 would be routinely usable handheld, the 60-250 really needs a tripod, or at least a monopod under it if you want to use it to greatest effect.

Isn't the difference one stop?

Anyways, this is a very tough decision. Eventually you will want both lens and the 50-135mm 60-250mm have huge overlaps. For me, I need the f/2.8 more than I need the extra reach, but it depends. 250mm is quite a bit of reach and I think it will be sufficient for most sports/ some wildlife.

If you have to flip a coin! Thats how I decided to get the 50-135mm over the 70-200mm!

I don't know about this, I think it depends on the person and where they are, etc - I thought I'd always need at least a monopod with my Sigma 100-300 f/4, but I never use one now, always shoot handheld. The big lenses get pretty heavy around the neck, but can produce shake-free images just fine using the same technique (hold barrel, elbows down, breath slow, go zen, snap.)

Pivoting around from a static location for fast shots (sports, BIF) would be good time to use a monopod, though.

Full stops are F1.4, F2.0, F2.8 and F4.0
So the FA 50mm is 2 stops faster with a very shallow DOF when wide open (a plus IMO for some situations) and the 50-135 is one stop faster which with a camera like the K20 or K-7 could be compensated much of the time by an ISO boost. But size and weight are going to be factors as Wheatfield says.

These are very different beasts and it's either size and length vs speed and shorter FL. You really have to determine which is most important for your shooting style.

Fair enough, and I actually have pretty steady hands. The 60-250, like it's shorter cousin the DA*50/1.4 is very sharp wide open, but get it stopped down a couple of stops and it's leaving your subject all sliced up and bleeding.
It really comes into it's own in the f/8 to f/11 range, but at that point, it's getting a little hard to handhold, even with shake reduction.
I do tend to shoot at lower ISO values though. I still have a hard time turning the ISO past 640.
