Comment by Daniel Bridge posted on Why is there a cut out section on top of Pentax lense hoods? at 08/01/2008 - 13:05
Hello Everybody,
This is my first post, so i'll try not to start by making a fool out of myself..
Anyway, if the removable part of the hood, is indeed removed, and placed on the top part of the lens, there will be no shadow in the frame, because teh flash is able to "go through" the hood and illuminate the scene almost perfectly.

Please let me know if this is a valuable contribution...
Welcome to the forum, please don't let this slightly less than illustrious start put you off.

The TiFF files have a bit more "pop" than these here too which are pretty heavily compressed for web display - I'll have another look at them though just to see !!

A worse test of reactions and AF speed I can barely imagine.
That's a challenge! I think about 1% of my shots were sharp enough.

<snip> Such test results always have to If I'd bought the Sigma I'd probably still be kicking myself and wishing I'd spent the extra on the 12-24 (or I'd have sold it, swallowed a loss and ended up with the Pentax anyway).
It's a lens I don't use a huge amount, but it would be the same if I'd bought the 12-24, so saving £300 was worthwhile for me.
Sharpness etc. with this lens is excellent, but I haven't tried the 12-24 to compare.

I use the same lens and it is one of my favorite lenses for macro work.

I've just seen that a Vivitar Series 1 90mm macro lens has appeared on e-bay. I think this is the one I remember, goes to 1:2 native and 1:1 with adapter. The dealer's blurb suggests it's a star product but there are lies, damn lies and ....
If I was going to bid, I would ask that the seller takes another photo of the adaptor, with less light shining on the element and a dark background. From this pic it looks a bit 'smoky', which I'm guessing could be fungus, or it might just be a smeary element? Could just be that pic though.
Also, the seller doesn't know his minimum from his maximum apertures...
Don't forget you'd also need an M42 adaptor.

[Interesting charts, Dan. I see that the 77mm Ltd is significantly sharper than the FA 100mm macro, which is sharper than the best Canon 100mm macro, which is sharper than this Sigma...
...Sigmas represent good value for money, but tell me, why do people buy Canniks?

Although, to be fair, the Canon tests were, I think, done on the 8mp 350D, so direct comparison with the K10D isn't quite as straightforward as it would be nice to think. The higher resolution of the sensor may well have a bearing on the results.

I'm fishing about for you Nathan, trying to make you feel less bad.
Oh, and by the way, you've made me feel old (I'm only 35) - I saw your '82' and thought, ah, poor thing, shouldn't be too harsh, he's probably still at school. Then had a look at your website, then at your myspace page, and thought - He's 25! Got to get used to people born in the 90's still being at school...
Nice pics on there by the way. Guessing the staircase is in Italy?
