I have been so delighted with the results from my SP 500 (and am enjoying going back to "manual everything photography") that I am splashing out on another Tamron SP lens, the 300 f5.6.

On paper it looks very good, with 1/3rd lifesize macro capability + good resolution and sharpness at distance (though it may be a bit dodgy on the CA front I read)

Anyway, for an investment of 49 its hardly going to break the bank :)

I wondered if anyone else has one of these already and if so, would care to share their views?

(I hope to have it by Monday so will let you know how I get on)

If it's the one from the mid 80's I had one at the time. Nice lens, good close focus but to slow for me so I replaced it with the Zuiko 300mm for the extra 2/3 of a stop brightness. Amusingly, the focus action on the Tamron was better than the Zuiko.

Thanks David, yes it is the one that finished in the '80s if I understand correctly, on the EM-5 of course it will be manual focus so the AF speed won't be a problem :)

Can you remember if purple fringing was a problem?

There was no such thing as pixel peeping in those days, as long as the shot looked good under a loupe on a light table publishers were happy. I don't remember the lens having chromatic aberrations so if it did they weren't bad. My EBC Fujinon 600mm f/5.6 did have noticeable CA at times but I still had plenty of shots published taken with it.

Thanks David, I'm looking forward to trying it out

Generally any metal Tamron lens sporting the "SP" bit will probably be pretty good..

I've had the chance to check this lens over very carefully and found that there is some fungus on the rear element (only visible in certain lights / angles).

Mifsuds who supplied the lens were very apologetic and have told me that they will refund the money and that I should keep the lens anyway to see if I can get some use from it - top quality service, its the first problem I've had with gear from them in over 7 years.

(Advice please, do I need to quarantine this lens to prevent the spread of fungus? I will try putting it into a hot / dry enviroment to see if I can kill it)

Anyway, despite that (and poor light) I've been having a quick play and whilst its not up to the optical quality of the Tamron SP500 mirror (because of the fungus?) it seems pretty good

Here are a few initial images:

Having owned the 300 and the 500 in the mid 80's I'd have expected the 300 to be better. Maybe I had a good sample of the 300 and a bad sample of the 500. I must admit to leaving my 500 sitting in the sun and it getting hot enough that the lubricant in focussing helicoid started running out, it never seemed as good after that.

Hmmm - maybe not so suprising? :)

(I was expecting the 300mm to be sharper than the 500 as well)
