Okey, then you have to be very steady on your hand or I donīt get it how you can get so good pictures without tripod. Or does it matter what kind of extension tubes you have?

I believe he was referring to the physical size of the lenses themselves - some of those are bigger than others, and that might matter to you.
This issue is sooo hard to decide anything about, since I like the weight of the pentax and at the same time I like the tamronīs price (can by something plus the macro... ) Okey, if I buy pentax it would be the WR-version.
I do want to get the best macro (regardless of price) since I donīt have so much money I could go and by the other one if Iīm not satisfied. And since I havenīt read any so much differences between the lenses (that I understand).

One other thing Iīm wondering about is if itīs possible with any macro lens also take pictures underneath things, for example a flower?

You'll always see me in defense of the sigma 105mm in threads like this. Its just an incredible lens. I've got 24 images in PPG (see signature) using the lens. Check out my flickr (also in my signiture) to see more images. If your to lazy for that here's a taste:



I've used the tamron 90mm and did not like the build/feal of it. YMMV

As I said above, in order for a shorter focal length length to provide the same magnification as a longer focal length one, it has to allow you to focus from closer. But we're talking about small differences here, and again, it just won't matter as far as how much detail you can get - 1:1 magnification is 1:1 magnification, regardless of whether it's done with a 90mm lens from 29cm away of with a 100mm lens from 30cm away. Exactly the same amount of the flower will fit in the frame either way: 1 inch, as I said previously, because 1:1 magnification always means 1 inch of the subject fits in the frame when using a camera with a sensor that is 1 inch wide. So if you want to see how much that is with the flowers in your garden, just take a ruler with you. 1:1 magnification means the picture will consist of 1 inch worth of flower - it's as simple as that. 1 inch is just a small part of larger flower like an iris, but it's a whole bunch of blossoms for smaller flowers like lilacs, for instance.
Agreed, but the perspective from both photos will be quite different, the shorter macro lens will include more of the background while the longer macro lens will throw the background into a smooth blurred backdrop. Another consideration when choosing an insect-shooting macro lens, apart from working distance.

That's because those lenses are way more similar than different. You could flip a coin to decide and do as well as any other method.

Interesting question. You'd need a lens that was physically small so you could fit it and the camera under the flower, and also that had a very short minimum focus distance. Seems like the DA35 would be way to go for this.

Here's an example of the effect of focal length on Bokeh (same subject, same background, same f-stop, same magnification):

BUT the working distance for the 90mm lens was 90/50 greater than that for the 50mm lens.

BUT at the same magnification the 90mm lens was 90/50 times harder to hold steady.

This is always the case: shorter lenses are easier to hand-hold, longer lenses show less well focused, more restricted background.

Longer lenses don't scare the bugs, shorter lenses do.
Longer lenses don't block the light, shorter lenses do.
Longer lenses weigh more.

I use an old smc 50mm f/1.4 with 50mm of extension tubes which gives me 1:1 magnification. Sometimes I don't use all 50mm, and get less than 1:1 depending on if I need it for my subject. If you are patient, you can get insect shots but you have to be really close (as in 1-2 inches). Flowers don't care how close you are. Best of all, the lens + extension tubes were only around $100 total from KEH.com. Great results for cheap. Just throwing this out there as an option.

If you want to try out macro shooting, this might be a route to try. You can still go all out and get a dedicated macro lens later if its the right kind of photography for you. I am happy with my results and don't really see the need for a more expensive lens.

+1 for this route. I have a reversing ring and focus is a pain. You think manual focus is hard? Try focusing by swaying =) I'm buying a macro lens too (sigma 70mm f/2.8 is more for me I think) but i've earned it in my mind

Every macro shooter I've ever talked to sets the magnification and moves back and forth to focus, me included.

I have noticed I do like bokeh (at least under f3.5)
I don't want to split hairs on this but all lenses have bokeh. Bokeh is the quality of the out-of-focus areas. Some lenses have good bokeh and some bad, but they all have it.

I have another suggestion; order the one you THINK you want today from B&H and if it does not meet expectations, return it for no charge and get the next lens in line. Its cheaper than renting one to test it out. Case in point, I was sure the Sigma 105mm macro was the one I wanted but returned it to B&H after 10 days for the Tamron 90mm and couldn't be happier. B&H makes returns quite easy by emailing you a UPS shipping label.
Thank you. We appreciate your suggesting ordering from us.

Yeah I agree just pick one. It'll be a learning session.

BTW, Digitalis love that pix. Just grossed my wife out.

"Swaying" plus catch-in-focus is a tried and true macro shooter method. I prefer the longer macro lenses myself.

I hate it how people think that life and death are only experienced by humans and little furry animals...we're all part of a chain, I was just documenting it.

I'll leave soon on a multi-month tent-camping trip, and I'm hauling (too) many lenses along. Too much macro, even. How much? An old M42 Macro-Takumar 50/4 just arrived yesterday; it goes, along with the M42 Vivitar-Komine 90/2.8 macro. And M42 Meyer Triopan 100/2.8 and Hanimar 135/3.5 with a thread reversal ring to stack Takumar 55/1.8 and 35/3.5 and 28/2.8 lenses for great magnification. And an M39 Industar-50/3.5 on tubes. And some mount reversal rings, just in case. And a Raynox DCR-250. And some diopter lenses.

And what did those cost? In total, rather less than a single AF macro lens.

Wow! I hope you needn't carry all those lenses far!

What? Those are just the start. I've got my usual AF zooms: DA10-17, DA18-55 (with filters) DA18-250, FA100-300, Lil'Bigma 170-500. Then various primes (working up): 16/2.8, 21/3.4, 24/2, 28/2.8, 35's, various 50's, 58/2, 85/2, the 90/2.8 macro, the 100/2.8, a couple 135's, 180/5.5 or 200/5.6, 240/4.5, 500/8. I'm trying to keep the total to around twenty or so lenses. And tubes. And filters. And both the K20D and ZX-M bodies. And a couple MF folders. And some P&S digicams. No, I won't carry everything all at once, and not far. I hope.
