First read, observe, then experiment. Without basic knowledge, experimenting on things you dont understand is wasting time. In order to experiment you need an hypothesis. Such hypothesis needs some basic knowledge. Read about the scientific method. Not a difficult thing really.
I think the basics of the scientific method is to learn. From there you take 2 differing parameters, in this case 2 lenses, and use them to see what happens. In this case I took a lens which is strong in one form of photography and compared it to another which is arguably, strong in another to see what the differences are. But instead of comparing the images to each other, you chose to attack me and my Hypothesis, not examine the images for their quality.

Experimenting without basic knowledge is the perfect way to create more confusion. The knowledgeable people are saying to you why this "experiment" is absurd, yet you keep your condescending attitude.....who is the snob again?
I started this thread to learn something, but mostly what I have received is attaches against me and my Lack of knowledge. Ironically, the best reply and most interesting response came from Rongnongno, usually the harshest of people.

Back in my school days, I had a teacher define true knowledge as the ability to explain a foreign concept to one's 90 year old mother. So CHG_CANON can you do that?

Do you not understand the leaning curve. With your own words, not a link, define Bokeh.

Dude, I know what bokeh is.

How you dare to bring logic into these threads?? Basics....whats that? I will tell what it is around here. Its the the single, most ignored, less known theme around here. With that in mind these people pretend to talk, start arguments and even do "experiments".....all about things they dont fully understand. At least its entertaining.
How else does one learn, if not by experimenting? Then we bring the results to a place (here) that has knowledgeable people to learn from. Don't be a snob, please. Why not help help someone to learn something, instead of putting them down for their lack of knowledge?

But he was trying to compare two lenses. He should have moved the macro back to the distance of the zoom.

I did, within 12 inches anyhow.

If you de-noise you soften so... You invalidated the potential sharpness difference.
Still the pime lens wins.
As to the differences?
In case you are not aware, the DoF depends on the focusing distance. A difference between the two? Yes. Nothing that makes one lens better than the other.

This is a wonderful example of what I wanted to gain with this post. At what Magnification did you work with these images. ( Guess I could do the same on my system, but why? u have already done it? )

Come on now! A BOKEH test at F9 and F18?
What next? Testing corner sharpness at F1.2 for landscape work?
As I see it, I have a very difficult time excepting the idea that op even understands the basics of Photography. Bokeh test at f18?

So please explain what bokeh is if not the out of focus parts of the image. Even at f18 there are noticeable regions of blur.
I repeat: what is life if not an experiment in learning?

The first sentence is pretty clear. 'Two lenses ... want to see the difference'

Not sure how this testing applies to "Bokeh&q... (show quote)
I went through that whole thought process before taking the first image, but the reason for this experiment was to compare the two lenses. So I had to work within the constraints of the Sigma. Its closest focusing distance is 1.5 meters and largest F-stop is f5.0.
Now, the next step in this exercise is to go outside and work with a little more distance and see how they COMPARE.

You might also consider that a prime lens has an optimal aperture and use that.
You are right again, but what is life if not an experiment in learning?

Good point, all images have been treated the same.
I cannot control the amount of work Dfine did.

I have a Canon 100mm Macro and a Sigma 100-400 Zoom and wanted to see what the difference in Bokeh would be. The first series is at F9 while the second is at f18. Truth be told, I misjudged the near distance focal range for the Sigma, so I had to move the camera back by almost a foot from the subject to get it in focus. Each image has been developed through Adobe RAW. I only used the Lens Correction tool there. When I imported the images to PS all I did was use Dfine 2 to get rid of noise.
If you DL the images, you will see the title of the image gives you all the info you need.
What do ya' think?

Love the model. I see no way to make her more enticing. The whole package is great. This set you have posted are the first ones by you I find appealing. Having said that, In this image the one thing that does not resonate is her back side. Her right cheek just barely sticks out from her left, making her butt look bigger than it really is. If only you could move to the left a little, or change the camera angle just a bit...Or perhaps clone out the slight shadow thrown by her left cheek?
