    Smile Macro problems.

    My journey into macro Photograhpy has plateaued, I seem to have reached the point where my lenses have run out of sharpness. Range of focus of my 105mm2.8 is probably only 4mm at best, and my 60mm is only about 3mm. this limits the angles at which I may capture insects to directly above, if I wish to see its entirety in focus. Up to now I have resisted the Photoshop way of going, where focus stacking could work. Normally I have only 1 or 2 seconds to compose focus and frame my subject, so stacking is not a choice. Experiments with zoom lenses has shown it is possible to get good results if the lighting is up to scratch, so I am considering a 2.8-200mm zoom as an option. Any one tried this before I commit 1500 to the subject.

    hi if you google macro lenses then it should come up with an article that WDC has on macro lenses so it may be worth a look

    Thanks Wave I took a look, maybe i'm looking for the impossible. This started when I photographed vernier scales to ascertain how much dof I had with my macro lenses and was dismayed with the results, so began wondering could I do better with a zoom lens and then crop down for size and got some impressive images that were better than the Macro lens.

    Calumet only 7mls away 45.60 per day, Great idea Wave will phone them and see if I can do a deal, they may allow me to use it on their premises for a reduced fee. If not a day out will be planned. Kind Regards Mike.

    It sound to me like an aperture problem not a lens issue

    Just looked at your macros, they seem to have an aperture of F6.3, to get crisp macros you need to be using at least F11 F16 is even better. Hope this helps... Graham

    Hope this doesn't muddy the water, when I did the tests on the vernier scale I was shooting at f16 and 1/30sec. I did try at f32 and used flash, but because the vernier gauge was shiny metal the point where i lost clarity was not clear. the f6.3 shots where probably the 200 zoom on auto. This may not be scientific but my second test object was a sharpie marker using the small writing as my focus.

    Apologies Graham I forgot to thank you , or to mention I tried with both my Nikon cameras to eliminate camera fault. This showed my d300s to underexpose a tad compared to the D90, I'm going old school at the moment shooting manual and using my light meter. many thanks Mike.

    No need to apologise Mike, I downloaded a focus chart a while ago if I can find the link I'll put it on the site... Graham
