Hi Mike! Thanks (again) for your advises and technical comments. When I took this photo, to get a good DOF, I've choosed F14. Of course I have to believe in your optical knowledge, but if I've took it with F5.6, I would not get such details...Am I right?... Regards

Hi Patsy! This old part of Lisbon is very rich in small details, I'm glad you enjoy it! Regards

Hi Joao,

I do like this view point and the scene capture.

I noticed your reply to Patsy, about this place being rich in detail.

For me, when I hear "detail", I think of using a good lens at its highest definition setting possible.  Now I understand that using F/14 with the Canon 24-105 F4 L lens produces a nice scene as shown here.

However, optically speaking, the details developed in this scene would be improved much more at F4 to F/5.6. I know this because I have formally tested this lens and all the Canon, Nikon, and so on lens in my optical lab facility. I have also field tested all these lens , too.

Again, for what you recorded , it might not be necessary to record any more details.

I view images for interesting content , but I study images for their highest definition possible.

This is mandatory in the scientific fields, the optical design and testing field that I have been involved in for over 45 years now.

Best Regards,  Mike
