Trying out my HD 8x Macro Achromatic Lens

Had to try it out despite not having the adapter/mount to attach it to my camera.
All shots were done free hand. One hand held the lens the other pressing the shutter, the camera is mounted to a tripod though.
Any chromatic aberration (learned that from ambro51) is from the lens not being level and hand shake, despite having the IS on.
I think once I can mount it properly, set the WB correctly it will produce some excellent images. My hand holding the lens blocked some of the light.
The lens
My best shot of a dime for sure. As we all know dimes are the toughest.

I love your pictures, but not these. You can get better closeups with one of those USB microscopes. It most likely is from not being mounted!!
Do you know how to stack images? If not, PM me, or I can describe the procedure here.
If it turns out the issue is lack of focus due to limited depth of field, then I think you have a winner lens there, much better than can be achieved with the USB microscopes IMO. USB scopes have fairly small apertures to achieve good depth of field, so they suffer from diffraction. They are always a bit blurry on the whole shot. The price you pay when you go to higher quality optics is more work to get a sharp image.

<< <i>I'm curious about the out of focus areas on these shots. If you move the camera toward or away from the coin, do they come into focus? Or are they out of focus no matter what you do? The reason I ask is that if they come into focus it means the quality of the lens is pretty good, but you need to do focus stacking to get a completely clear image. I'm encouraged by many of the shots, as they do look like much of the frame is sharp. I'm hoping the blurry shots are simply not well-focused.

Yes.... What Ray said!! And others..
Shows lots of potential if you lock it down. Some are super sharp!
Focus by small movements of the camera with macro...
Nice work!!

It's from holding the lens in my hand while hitting the shutter. It's a combination of the lens not being square to the coin and bit of hand shake.
Hopefully the adapter/mount comes soon. Really blows that I have two lenses and no way to mount it. I even payed extra for priory
shipping, so the adapter would arrive before the lenses. Just the way it goes, I don't have what I need. When it does arrive, you can bet that I'll be a shooting madman trying to dial it in. Correction, I will dial it in
I should think you would have taped it to a tube or something at least!
Lots of potential there!!

Bigger issue I see is in holding the camera while you shoot the shot. What are you going to use as a copy stand? You need fine focus capability at the magnifications you're working with.

I just couldn't wait for the mount, day off I wanna shoot macro NOW!

<< <i>Stacking is pretty cool, and Ray has lots of good advice he shared with me. >>
a BIG +1

Stacking will help with the narrow depth of field for the sharp areas of the image.
Another way to get good close-ups froma point and shoot is to get a cheap microscope and put the camera right up to the eyepiece. The camera doesn't need to be in macro mode as the apparent image the camera is focusing on is a couple feet away. Below is an image shoot with my point and shoot through a cheap microscope.
Mark- Crazy how you nailed that through an eye piece, very well done.

That link Lance posted is a good answer. rpmsrpms knows a lot more about objectives. I was surprised by how cheap it was to get set up.
