Yes I know that, but for the $100.00 extra that I save, I can buy a lens hood for it, and I don't mind the plastic mount (unless you can tell me of something really wrong with them).

Absolutely - just making sure. The DA L also misses the quick shift focus. As far as I know the plastic mount does not cause any particular issues. I would go with the DA for a little more if an option at all, but I realize you can increment yourself to death. I would take the DA L 55-300 any day over a metal mount 50-200... Henry's appears to be a good place to shop,in Canada, so go for it...

One last question if you dont' mind, What's the quick shift focus? How would it benefit me when using my K-50? The 50-200 is really that much worse than the 55-300? Can you elaborate?

Thanks again.

Yep, I wouldn't worry about the plastic mount plate. But the quick shift is very nice to have at times. But by all means, I'd take the DA L over the 50-200 any day.

So: HD DA 55-300 WR > SMC DA 55-300 > DA L 55-300 > DA 50-200 WR

If you need WR, I'd go with this one. PENTAX HIGH DEFINITION DA 55-300MM F4-5.8 ED WR LENS 22270

If you don't need WR the DA L is a great lens. Quick shift is a nice to have item in my opinion.

So here's the differences between the three versions:
HD DA: Has WR, has better coatings than DA and DA L, has quick shift, metal mount, lens hood included.
DA: Has quick shift, metal mount, lens hood included.
DA L: No quick shift, plastic mount, no lens hood.

All three have the same optical formula, except for coatings. All three should perform very similarly with the exception of slightly better flare resistance on the HD DA version.

Quick shift lets you change the focus after you have autofocused with no damage to the autofocus mechanism. Don't do that with a non-quick shift lens! It's useful for when the autofocus misses.

Yes - 55-300 is that much better. And a 70-200/2.8 is that much better again Welcome to LBA (lens buyers addiction). There always seems a reason to upgrade....

The quick focus allows you to override the autofocus without having to switch to manual. On the DA L you have to switch to manual focus. I personally use a center focus point and recompose after focusing so don't really use (or more accurately I forget it since not all my lenses have it - no FA lenses have it).

SO when you end up selling your DA due to LBA, you probably will do a little better than when selling your DA L. On the other hand you can upgrade your DA L to the DA and postpone getting into the more expensive lenses

You can't loose

But It's ok to change to manual focus from auto right? You're speaking of manually force-focusing the camera while it's still set to auto focus correct?

Can you clarify what is it that makes it so much better?

Without quick focus you can still switch to manual focus - you just can't override autofocus.

The 55-300 will be sharper than 50-200mm at same focal length. You may even gain a little light at 200mm. Check out the reviews. Remember that most people will rate with consideration for the price, so it sometimes is hard to compare ratings. The 50-200 has the advantage of being much smaller, and it still much better than a point and shoot. Everything is relative...

I was just trying to determine if it's worth getting a lens that's better for my K-50 which is only a upper-mid level camera, not a professional one like the others.

I think the 55-300 is about a half-stop faster at 200mm, f4.5 vs. f5.6.

Yes. It is nearly always a good idea. The K-50 uses the same sensor as the former top of the line camera, so output is almost identical. It can take advantage of great lenses. It has sealing so WR or * lenses are useful. The body is more likely to wear out or become obsolete than a lens. If you upgrade, you can immediately use your good lenses, not figure out how to sell the bad ones and get the ones you could have bought.

I second that. You can easily use far more expensive lenses with your K-50 and benefit from it.

I regularly use expensive lenses on my k-01 and don't think twice about it. I will go out of the way to use my better lenses over, say, my 18-135mm whenever I have a option. More expensive cameras (at least from roughly the same generation) mostly provide more features than their mid line or even cheaper counterparts.

I have both, and my 55-300 is notably better than the 50-200 wr at every focal length and aperture. I would definitely recommend the 55-300 of the two. The weather sealing is the only point the 50-200 wins IMO, and it is somewhat smaller in size.
This question comes up again and again. I also have both, the DA 50-200 WR and the SMC DA 55-300. In practice there is not that much difference between the two. The DA 50-200 is considerably smaller and lighter.

DA 50-200 WR - SMC DA 55-300

Regarding the 55-300 vs. the 50-200, My experience is that the relative performance will depend more on the copy you get than the design of the lenses. So a good copy of the 50-200 will easily outperform a poor copy of the 55-300. If you get an equally good copy of both, the 55-300 will probably be better, but the odds of getting a good copy of both may not be in your favor. You could also consider the Tamron 70-300, which seems to be available used for less than an equivalent-condition 55-300 (even the L variety.) That choice would depend somewhat on whether the 15mm difference at the low end will be important to you, of course.

I would think it would be difficult to know the parameters for what constitutes an "equally good copy".

Regardless, I must be lucky and have a good copy of the 50-200. These shots are from the standard version, original JPEG's, and taken with the K-r. The last two were at the full 200mm.

As your pictures point out, you can certainly get excellent pictures from any reasonably good copy of any of the lenses. With both the 50-200 and the 55-300, most of the issues I've found only show up in the corners or edges, so they wouldn't be visible in many pictures anyway. You'd see them if, for example, you were photographing foliage on a mountainside, utilizing the entire frame.

My point was that it's more important to have a good copy than to worry about the theoretical performance differences between the 50-200 and 55-300.
