FlowerPods

Les Saucier designed these FlowerPod clamps to hold flower blooms or anything else in the field primarily. They are extremely useful if the wind is blowing a little bit and you need to keep something still. They work better (and are more gentle) than Plamps (my opinion). They come with a mini tripod...

Simple macro rig/stand made of wood

http://www.photomacrography.net/forum/userpix/1744_1210210012018_3.jpg I'm just a beginner, but I'm trying. I made this macro stand out of wood I got at Home Depot. I have a Nikon CFI BE Plan Achromat 4X/0.10 objective attached to a Nikon micro Nikkor 105mm lens attached to a Nikon D300. The SB-800...

Thank you very much

Chris - sorry, I wasn't clear. I was talking about the "hood" on the 4x objective. Rik called it a hood so I used that term. It's like a collar on the objective that is used to print the information on the objective and I suppose to protect the lens. Thanks for all your advice. Thanks, Rik. Good adv...

more info

I have the Nikon CFI BE Plan Achromat 4X/0.10 objective and the Nikon AF-S micro Nikkor 105mm 1:2.8 G ED lens. Yes, I'm at 2.8 and diaphram wide open. I do not get vignetting when I set the focus on the lens to the closest focus point (the other end from infinity). So there is an issue of quality (n...

more info

I didn't know there was a hood, Rik. I was all set to say there is no hood on that objective and when I went to look at it, sure enough, the black hood with all the printed objective information screws right off. Who knew. I have the Nikon 105mm macro and then a 62-52mm step down ring, then a diaphr...

Where to focus macro lens with 4x objective attached

I have a 105mm macro attached to a nikon D300 with a 4x objective attached to the lens. Should I be focusing the lens on its closest point as opposed to at infinity? Because I get vignetting when I focus at infinity. Thank you.

so no 4x?

Thanks, Chris. So I don't get 4x with a 4x objective on a 105 macro. What lens would I need to use to get 4x? A 200mm lens? Is that practical (it's so long!).

4X objective on 105mm macro magnification question

I mounted the CFI BE Plan Achromat 4X on my Nikon 105mm macro. I shot a micrometer to check the magnification and I got 2.84x instead of 4x. I then noticed the focus of the macro was somewhere in the middle of its range. Should I set it on infinity or the closest focus point. My camera battery just ...

Wow....thank you

Perfect and precise information and thank you for the links. This helps me a lot because I have in the past gotten close but there seem to be a lot of nuances putting all the different pieces together. I'll be busy tomorrow morning ordering everything. I will also submit a post and picture of my DIY...

Ok, now how to get the objectives attached...

I will use my Nikon 105mm and Nikon 200mm macro lenses. They both have 62mm filter threads. I looked at the link to the Nikon CFI BE Plan Achromat Objectives and it doesn't say what thread the objectives use. Is it the RMS thread like I used for my bellows setup? And then I'll just need a step up ri...

Calculating magnification using objectives on cameras

A very basic question. I have a Nikon Achromatic Finite Conjugate Objective 10x mounted on a bellows and my Nikon D300. I have the bellows extended so I have 150mm distrance from the base of the objective to the sensor. So I am assuming I'm achieving 10x magnification. If I reduce the bellows extens...

Can you recommend a good 4x or 5x objective

Based on information within www.photomacrography.net I purchased a Nikon Achromatic Finite Conjugate Objective 10x NT59-935 from EdmondOptics and mounted it on a bellows with my Nikon D300. RMS thread to M42 and it works great. Can anyone please recommend a 4x or 5x objective (I would like to also t...

A place to look for innexpensive/free microscopy equipment

I'm retired but I still give biotechnology talks at some universities. I gave one on Friday and happened to mention to my sponsoring professor that I was looking for a few microsope objectives and a moveable specimen stage. He said one of the departments has been trying for a year or two to give awa...

Chris - Thank you very much for your thoughtful reply. 1) I already ordered a flat adapter on eBay suggested by Chris R. It's a cheap one but should get me in the game. 2) The PB-5 Nikon bellows does allow a D200 and D300 to mount. You just have to swivel the bellows collar to portrait from landscap...
