Early Bird

[Alan]

Finally managed to get a sharp bird photo with the Tamron 16-300mm on the D7000 this morning. It could have been a fluke as all the other 8 shots were OOF



f/6 1/1600 400 IS0 @ 175 mm - small crop, hand held

Why do you think this one is sharp? And the others soft?

[Phoenix]

Might be worth doing a still test. rather than on moving subjects to see if focus of the lens suits your camera.

[LJG]

Nothing wrong with that shot Alan considering you had such harsh light to contend with.

[Sully]

Interesting settings used Alan ..... did you set the iso400?

Not sure Stephen - maybe the nut behind the viewfinder needs some adjustment

Thanks Jo - tried that (even with tripod and Vibration Control turned off) - sometimes good - often not. It's back focusing something terrible and another adjustment seemed to help a bit. The daffodils in 'Spring" comp seem ok.

Thanks Lloyd - sometimes it's spot on

I did set the ISO, but I had the camera on 'P' mode, so it chose the shutter and aperture. I might try Auto Aperture and set a higher shutter speed - though I would have thought 1/1600 with VC on would have been enough. That is if it's a camera movement problem rather than a focusing problem.

Thanks for your thoughts and suggestions

[Phoenix]

I know this might sound a little silly... but do you have it set on auto focus instead of manual?

[Alan]

I do Jo - and it's not silly - I have been known to make that mistake - I listen for the lock on sound and wait to see if it, (hopefully) pops into focus.

What I don't understand is that, if it looks super sharp in the viewfinder, why doesn't that translate into a sharp image if prisms and mirrors and focal planes align enough to provide a crisp viewfinder image - what's happening in the internals to cause it to front or back focus? And what's the point of relying on the viewfinder anyway? And how do people starting out ever come to grips with getting sharp images if this is something else they have to deal with.

You get what you pay for.....

[Phoenix]

Perhaps you need to set the diopter?

[Alan]

Thanks Jo - done that - but it's set on AF, so I'm not trying to focus it myself.

Appreciate your, and everyone's help.

I'll live with it, and try to sort it, out and won't complain anymore - first world problem

Cheers

[avkomp]

testing on stationary stuff would be a good plan.checking for front and back focus etc. eliminate all the stuff it cant be.
what remains is the solution............ apparently

[Ironwood]

Is it just on the Tamron Alan ? Does the 300 f4 give you consistency ?

[Alan]

The 300mm Nikon behaves itself with a Nikon camera Brad.

I'm starting to get better results with member's help

The blacks have come up detailed and sharp and black is a hard colour for that so you've done well.
