Hi,
I am using a completely manual lens with my D5100. I need to set the aperture but the procedure in the manual and from multiple videos I found doesn't work.
I am in manual mode. I am shooting birds.
I can set the shutter speed with the dial but when I hold the +/- button down and turn the dial, it only shows f----. and flashes that.
This is a redcat telescope but it attaches just like a lens,
I am getting some awesome pics of birds with this but the focus range is very short because the aperture is off (I think). If I get the birds nose in focus, it is beginning to blur out by its tail.
Thanks
Jeff
