I'm surprised you couldn't find any reviews of the Tamron 70-300 Di. It's quite a popular lens, or at least was quite popular before the Pentax 55-300 was released.

The Tamron and Sigma 70-300 lenses were both considered to be excellent in terms of "bang for the buck". In general, the Tamron was sharper than the Sigma (and in general considered very sharp) but was subject to purple fringing problems in high contrast situations. The Sigma had little to no PF problems but was not quite as sharp.

It sounds like the Pentax 55-300 is in general better than either of these, BUT it is much more expensive.

I still have my 70-300 and use it whenever I need reach but don't want to lug around my Bigma.

I may have just got taken.

I called to order the DA 55-300 and ended up buying the Tamron 75-300 plus a teleconverter. The salesman (who does a lot of sports photography) swears I will only lose one fstop with the converter. He talked so fast I said yes before I knew what I was doing! I'm not usu. so gullable. He DID give me a 30 day money back guarentee...so I thought "what do I have to lose," other than the shipping cost. Thanks for the help everyone. I guess I'll see what happens.
Good for you!

What kind of TC? I have not heard of many using a converter with zooms so I'd be quite curious to know how your Tammy does, especially when it comes to AF at max focal length.

Looking forward to seeing some pictures with that combo.

Here's a comparison between the 55-300 v. Tamron 70-300 + DA*300 as reference

I think it is a Kenko 1.5 ??? I wasn't planning on a converter, so I haven't done my homework on them. After I placed the order, I did look this up and it doesn't seem to be a good choice. I will post some shots as soon as I get something for sure!

GAH!! Looks like from this I made the wrong choice. See, I called intending to order the 55-300. I do have a 30 day money back guarantee, so if this Tamron doesn't do what I need it to, I can send it back.

Well, you won't lose more than one stop with the TC, that much is true, But you will lose a considerable amount of image quality, and it will also make focusing that much slower / less reliable because there isn't as much light to work with. And cheap TC's on cheap zoom's seldom do well. The Kenko TC is OK - perfectly average by TC standards - but like any TC does better with better lenses, and all else equal, does better with primes than zooms.

I have no experience with Tamron, but am thoroughly enjoying the DA 55-300mm. As the weather is just turning now, I don't really have any outdoor soccer to show you, but if you take a second to check the gallery below, you will see how well it handled indoor ice hockey.

Well, the debate between the Tammy and the Pentax rages on. They are very close.

I own the 55~300 for shooting college Lacrosse and I am VERY happy with my choice.

Here are a few representative half-size images and a link to some more (these were done the week after I got the lens and just a month after I started shooting again after a 20 year hiatus):

I have the Tamron di 70-300 (I assume we are talking about the same lens & the
'75' is a typo).

I bought it for $169aud before the Pentax 55-300 was released. Its fair to say that if the Pentax was on the market I may well have gone that way....purely for snobbery .

Back to the Tammy. Don't be frightened of it, it is a very good lens for the money and is quite capable of giving you excellent results. I posted some shots back around December in two threads "Surfs Up" and "your never too old to learn", there was a collection of shots from the Sigma 135-400 & Tammy, but exif is intact).
The Tammy is lightweight (by comparison) and not overly large.

The other option you might consider (without knowing your budget) is either the Tamron or Sigma 70-200 f2.8 with the TC. The f2.8 could be very handy.

Hi All,

I didn't get the lens on time. I was not happy at all. The salesman assured me I would have it by Friday, so I could use it Saturday. It is supposed to be here sometime today, but I don't know when I will have a chance to use it. Not sure when the next game is. Thanks for all the replies everyone-samples have been very helpful!

I have lots of outdoor soccer with the Pentax 55-300 on my flickr. Some are with the 50-135 but that can be discerned in the exif. I posted some over in the Post your Photos forum under "Soccer!" if you want to see some examples.

I won't bore everyone by posting more shots here.

Nope, not a typo..this is the 75-300 f/4-5.6 macro lens.

Tamron AF 70-300mm F/4-5.6 Di LD Macro 1:2 Lens - Digital Camera Warehouse Australia

I do not know anything about the 75-300.
