Not sure if this is accepted, but since I do not own a macro lens, a good one, I am doing something else to achieve the result. So I am currently using the cheaper, and a little harder way: Reversed Nikkor 55-200mm standard kit lens.

This is my first project made with a normal house spider "Tegenaria domestica" who was in my captivity for a week, in a nice big glass jar, with moss, leaves and some earth for his comfort. I fed him daily, and watched the hunting I provided for him as I was doing my best to catch the shots need it for this little project.

So here is my best result so far: A set of 5 shots, focus-stacked in Photoshop for a total sharpness of the entire spider.

Reverse-mounting a lens is a time-tested method for macro-photography. You will find that reversing a PRIME lens will result in better images than a reversed zoom lens. Read more here:

Thanx for the tip Nikonian72. I read about and became aware about the better result with prime lenses. It's a matter of time before getting one. Just too many lenses I want to buy and so little cash :)

Your image looks quite good on enlargement. Well done!
In the U.S., this spider is not commonly known as a "house spider". Better ID pending.

Thanx again Nikonian.
I was pretty amazed myself with the result.

I think this is proper species: Tegenaria domestica

Straight manual 28-mm to 35-mm manual lenses work best for reverse-mounting. There are hundreds of these "older" design lenses available for reasonable prices.

There is also a device for closing the lens' diaphragm (aperture) just before you take the photo, so you can focus wide-open, then instantly close-down for image capture. The Nikon BR-6 is pictured below.

Michael Shahan uses bellows with reversed lens, in the field. The second image is one of his field set-ups.

I've just finished reading the link you provided me, and that BR-6 caught my attention. Now, I am using a little tape to lock the ring all the way wide open. Great article there. thanx again.

Thank you, Brenda. This was a project that took me a while to get the hang of it. It's not that easy as I discovered. Learned a lot from this and was happy about the result myself. Too bad the winter is coming and I am suffering for candidates insects for further macro projects.

Whether you use a reversed-lens or a proper macro lens, ILLUMINATION is key for best DoF (f/16) at a decent shutter duration (1/200-sec). Focus-stacking is usually best at f/5.6, so less critical on lighting. Never-the-less, consider obtaining a good speedlight. Look here (pages 4 through 6) for dozens of different combinations: http://www.uglyhedgehog.com/t-32754-4.html

Indeed light is essential on these projects.
I did experiment a lot with different lights and angles. But for this one , I was actually lucky enough with the bright sunny day, and a little more light from my fishing headlamp.

My problem is that I am doing photography like fishing. A big hobby where I invest a lot of money, but never earn anything besides satisfaction :D . But from the links you provided, I should get a speedlight anyway.
Thanx for all the good link. They are really handy. Learned a couple of thing already.

Thx Tinusbum - Indeed is a lot harder. For me it was (still is) my only choice and the cheapest way to have a look at the macro stuff. Think I paid like $3 for my ring.

At first I thought it was just reverse the lens, shoot and bang, you have a macro. Until I tried it. I saw amazing good close-ups on the net with reverse lenses, but did not know that it involve post-processing. Got a fair deal of frustration in the the beginning, but I sat down and googled, and read more and more about it, until I understood what people are doing. And that's how i discovered focus-stacking. Once I understood that, it became much easier. The result gave me much pleasure and confidence that I can produce decent macro photos. I will invest in a good macro lens in the end, to simplify the process, but this experience is also good to have, and gives me the opportunity to do some macro while I have the chance.
