Help!!! DA 50-200mm F4-5.6 ED or FA 100-300mm F4.7-5.8?

Hi, everyone!

I'm new like member but always consult the threads and I like too much!

I need a help to buying one of these two lenses:
SMC Pentax-FA 100-300mm F4.7-5.8 Reviews - Pentax Lens Reviews & Pentax Lens Database
SMC Pentax-DA 50-200mm F4-5.6 ED Reviews - Pentax Lens Reviews & Pentax Lens Database

I have a *istDL with the 18-55. So, I was inclined to buy the original pair for it, the DA 50-200.
But after reading about the FA 100-300, I'm not sure anymore. It has better average rating and many users praised the sharpness for the price.

I have the opportunity to buy both at the same price. I have no problems with the range of the 100-300, I want to buy the best optics for a poor newbie!

Every opinion will help!

Thanks and sory by the ugly English...

You should also check out SIGMA 50-200mm F4-5.6 DC OS. I have it and I'd swear by it anyday! Gives excellent consistent results for a very cheap price.

For IQ and range I would go with the FA 100-300mm.
DA 50-200mm has Quick Shift, is smaller, and is wider on the short end but the FA 100-300mm isn't much heavier and has much better IQ IMHO.
I used to own the DA 50-200mm but eventually sold it and now own a FA 100-300mm.
One question I would ask is, how important is the 50-100mm range verus the 200-300mm range.
As a general telephoto zoom the DA 50-200mm is a great lens, if you are planning on doing birding and such, the FA 100-300mm is much better.

I have also used the Sigma 50-200mm (HSM Version) only for a brief time and I was very impressed with it.

I overpaid (US$120) for the FA100-300 (silver) and I love it. IQ: sharpness, saturation, contrast, bokeh, are superb. I'm no birder, but it has produced my best bird shots. It's light (380g) but not small, a bit loud in AF, looks kinda geeky on my black K20D, but it sure delivers! I also have a Lil'Bigma 170-500 (1270g). That is 3.3x heavier; I'm much more likely to actually carry and use the FA100-300. IMHO at around US$100 it's the best deal around in that longish range.

Another option would be the DA 55-300mm: it combines the best of both worlds (minus the price):

Pentax SMCP-DA 55-300mm f/4-5.8 ED Autofocus Lens 21720 B&H

Thanks! Found just one seller on E-Bay that ships to Brazil and the price with shipping and taxes becomes more expensive than the DA and FA I found here in Brazil. Still looking for other alternative!

Thanks! It seems to me that the quality of the 100-300 make it a good lens to have, even if not used often. I need other opinion: it is a good idea giving up the opportunity to buy the 100-300 for a price lower than the 50-200 to have the 50-100 range? What do you think about?

Thanks! Yes, I thought it, but the price is deterrent. The $350 with brazilian taxes will be more than $450, with no shipping. It would cost a total of 800 in brazilian cash, against 300 or 400 of the 100-300 50-200, both used.

There is coverage (range), and there is character. The best way to cover a great range is with a superzoom like an 18-250. A simple way to cover a slightly greater range is with an 18-55 and a 50-200 or 55-300. Or with an 18-135 and the 100-300. But none of these are especially fast, nor do they possess distinguishing character. Gaps in range can be covered by zooming with your feet -- move forward with the 18-55, move back with the 100-300. But neither has shallow DOF. In between those, a cheap manual Fast Fifty or a portrait-type lens around 75-85mm is great. That's the best I can advise.

Gotta go now, it's time to roam this city some more! Good luck.

Hi, everyone!

The FA 100-300 won! The price and image quality were decisive. Thanks to all opinions!

Hi!
First image with the FA 100-300.
I am very pleased with the lens. She showed me that has more to offer if I improve my technique ...
Thanks to everyone who gave their opinion about the choice!
