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!
