EF100mm Macro - Pin Sharp??

Re: EF100mm Macro - Pin Sharp??

Hi Chris,

The 60mm is optically very similar to the 100mm, possibly a tad sharper. The drawback is that you have to get closer to the subject (minimum working focal distance ~9cm). Add the 250D and you have to get very close - probably the equivalent of a 40mm lens?. OK for subjects that don't run away, but I bought a Sigma 180mm macro for insects etc.

I used RSP to convert the raw file and upped the detail extraction a bit. It's a dangerous thing to do as RSP gets perilously close to the Nyquist frequency at the best of times, but this one was OK.

No sharpening as such, just a de-blur with Focus Magic using the minimum 1px blur radius to counteract the effect of the AA filter.

100% crop.

Regards,

Stuart

Thanks everyone for the 1,000+ views of this thread, and to those of you who confronted the frustration of trying to photo a pin head....
However - no attempt by anyone with the new version of the 100mm Macro. If any of you are the lucky owners of such how about giving it a try and posting the results??
Cheers, Chris.

I have the new 100mm L and I'll give photographing a needle/pin during the Holiday and post the results for you!

Thank you, Sir L - look forward to seeing that and hearing how you tackle the challenges of lighting, focus and avoiding any vibration (although the floor of your castle should give a solid base!!)
Cheers, Chris.
