A REALLY neat idea for a shot! And, all those COLORS! I am curious as to what you used to produce such a beautiful spectrum in the background.
As Uwe said, it's got to more than flashlights!
Klaus, how is the 105 macro working for you? If you needed to repurchase a dedicated macro lens, would it still be the 105? Or would it be the 50, or 70, or 150, or 180?
I will want to definitely pick up a macro for the SD14, but am unsure which way to go. My general macro shooting would not be for insects or anything that might move - it would be more for flowers and other organic elements.
I think the spectrum is reflection from a CD.
Take a CD and let the light reflect you will see the spectrum.
Knowing Klaus,the remaining he has done in his digital darkroom.
On the macro lenses,I would go for the 150.
I had the whole line for tests for a weekend.
All of them are very close.
To keep it short,I kept the 150mm and the 70mm.
If I had to choose again,the 150 would be it.
Hope it helps.
though I am very much in macro photography, the 105mm is the only "real" macro lens I have.
It was pure a coincidence that I got this the other day from the internet at a very considerable price.
No doubt ... it is a wonderful lens with a unique performance as far as sharpness and contrast (even fully open) are concerned.
Anyway, there are means and ways to achieve similar perfect image results with our Do It Yourself-measures.
You guys are a TREASURE of information. I never realized that you are engaged in so much experimentation; this is an area that I have bookmarked, as I know I will eventually want to create the same types of auxiliary components for increasing macro ability.
I truly appreciate this forum. It is full of good things.
NAH ... Jim ... I am sure you will be using your 105mm for many many years! Maybe I will need your advice with the lens!!
So far, I did not manage much more than test-shots with it. I am very much looking forward for the next macro-season. Until then I will have to find a solution to adapt my old SOLIGOR ring-flash to it. Normally It fits filter mounts up to just 55mm.
I respect the opinions on this forum. After all, all I have to do is look at the images that you folks create!
I have decided to cancel the order for the 50mm, based on the VERY logical and very good information above.
I "see the light"
about having a bit of distance for macro images.
Even though I don't generally shoot insects and small life forms, you are correct in that having a bit of distance
to work with can only be a proviso for better usage of the macro fields.
In addition, I do have, as mentioned earlier, a very nice 55/1.8 Takumar and extension tubes that might be
just as "handy" as the Sigma 50. And of COURSE I should look at a bit longer focal lengths in the M42
standard. In fact, I may be able to purchase a Kiron 105/2.5 that goes to 1:1. I know that this is a fairly
highly renowned lens, so it is probably worth a try.
THANK YOU! This is one of the benefits of the forum, and I DO tend to listen to advice!
Jim (or anybody), I understand that most Pentax K mount lenses can be mounted on the SA mount? I have also heard that you have to cut off the aperture level to avoid it hitting the IR Filter/Dust Protector. Is this the way it goes with the Pentax K lenses?
basicly you can put Pentax K lenses on a Sigma.
Ok,you have to remove or cut the aperture level first.
I think removing is the better way,no dust, and it can be put back if needed.
The other thing is the Pentax K bayonet is a little bit smaller than the Sigma.
On a Sigma you can shift the lense sideways ~1mm.
If you can live with that go ahead.
BTW: @ Jim + Larry,you guys give me a hard time to follow your conerversation.
I have to use my DCE (Dictionary of Contemporary English) more and more.
