What sort of flash or strobe and lens did you create that photo with? It is stunning in it's simplicity in my opinion!!.

That is an excellent example of what is truly tack sharp.

Thanks guys, this was an out-take shot from a photoshoot we did for a billboard.

Lighting was a single ring light, bare on a black background

OK, now knowing the level of equipment and skill in this photograph, I don't feel QUITE so bad about not being able to achieve that just yet with my current skills and equipment. I know equipment isn't everything but I'm sure that in some cases it can help a lot. Combine skill and equipment and you get excellent.
Something to shoot for. (no pun intended!)

JJ:

Also, the sharpness of the image will be determined by the f-stop used. Higher f-stop does not mean "sharper" just greater depth of field. After about f11 or f16 you start losing sharpness due to diffraction. We are willing to give up the sharpness for the better DoF. Lighting will also play a role. Soft lighting can improve sharpness, and flash, under the right conditions, can reduce it. What we are hoping for is a rendering of the subject with as much detail as we can get!

Photography is always a balancing act between what you want and what you can get.

TACK SHARP

Your eyeballs bleed when you look. Handle the lens and your fingers are cut off. Drop the lens on your Chuhuahua-dog and poor Pepe is sliced in half. Beware of sharp lenses -- they are dangerous. Always file-down your lenses so they have no sharp edges.

Tack sharp is whatever you make it out to be... to me the DA 40 and FA 35 is the benchmark for a sharp prime. Sharpness isn't everything though! I actually prefer the colors of my 35mm tak than the FA 35.

As shown by the image posted earlier too, the lighting very much affects your perception of sharpness. Most of my flash photos always look sharper than non-flash ones, although that might also come partly from stopping down the lens when using flash

Yes, lighting makes a huge difference to image sharpness, as it helps to eliminate other factors that contribute to subject softness - motion blur, camera shake, insufficient contrast/exposure...

The lens that exemplifies sharpness to me is the FA 100 f/2.8 macro. Yes, the FA and DA limiteds are awesome, and the Sigma 70 is brutal in that department also, but from what I see on the screen my eyes keep coming back to the amazing microcontrast and sharpness produced by the FA 100 macro at the f/8-16 range.

Hmmm. Not bad for a kit lens (Hasselblad Australia has H4D-40 with 80mm f/2.8 as a 'Kit' for $AUS22,995)

Thanks. I'll be honest though, maybe my EQUIPMENT can but I don't think that I'M quite up to that level yet!
I can certainly flood a room with light but I'm stlll working on getting it to do what I want WITHOUT blinding the poor photographic victim.
Certainly something to aspire to though!

Are you using just your AF540 & umbrella to light her? On the crop I can actually see one hair that probably shouldn't be there.

It certainly shows what can be achieved with our cameras & lenses.

Very nice photo.
