Thanks for the quizz. I should have guessed. I got a very similar rendering with the shots posted on this thread.

Cheers!

Tamron vs Sigma

As a matter of interest, since I have an opportunity to buy one of these dirt cheap - has anyone tried a similar experiment with the Sigma 70-300, both the APO version and the non-APO?

One of my colleagues has a non-APO version of the Sigma 70-300 that I can buy for $100. But if the Tamron is significantly better, then I'll go that way. However, if the Sigma can "cut it" with the Tamron, not just as a "macro" but also at the long end, then for $100 it would be worthwhile having in the backup bag.

Anyone any comments?

Thanks in advance

Great pics! You have to be super conscious of the lighting\contrast (to avoid CA) when you shoot with the Tamron 70-300, but as these pics show, the results can be amazing.

This was taken with my Sigma 70-300 APO



It is my very first macro.... I am not a bit flower guy... my engineering background make me see beauty in more mechanical things.

The shots in the openning post are just wow.

I saw this thread earlier today and I would not have guessed that it was this lens, and I have own it! Of course, I haven't tried the macro function much as of yet. What kills me is that I bought this lens used for around $20! Talk about a good deal!

Abbazz great shots in that other thread!

It seems like almost no one goes for the non-APO version.

The general consensus is:
Tamron - Sharp but prone to purple fringing, very little sample variance
Sigma APO - Tends to be softer with lots of sample variance, but almost no PF.
Sigma non-APO - A non-APO lens would remove the Sigma's main advantage over the Tamron (CA/PF), so no one buys it as the Tamron is nearly the same price as the non-APO.

Hooti Hoo... I win

It will be noted in my acceptance speech at the awards banquet, that I guessed it before the last set of clues...

And to be honest... and I know some will say I am full of s_it, I guessed it because of the colors. It looked exactly like the colors I get from mine. That fancy hi-res sensor can turn the tammy into a good macro lens, but it still has Tamron 70-300 colors...

what is my prize? Your K100d super? Or maybe some other K20d owners old K10d?

Entropy - many thanks for that summary and comparison. Very much appreciated

I think I'll give the non-APO Sigma a miss, and go for the Tamron. Unless, of course, the Pentax DA* 55-300 suddenly puts in an appearance......
