Nobody told me the DA16-45 was a Macro lens!

Just picked up a nice, used DA16-45. Never tried one before.

Haven't done much with it but the first thing that made my eyes pop was the close focus distance!

Error on the PentaxForums review page. Close focus distance is not 28cm as stated. It's like 8cm. Have I got a bad copy? Er, limited edition macro copy?

This lens deserves the macro designation as much or more than all those Sigma/Tamron pseudo macros. (DA21 is a candidate too!)

What's up, DA16-45 experienced users? What else haven't you been telling us?

Where are you measuring from?

Isn't it 28 cm from the sensor?

Something that is often misunderstood: minimum focus distance is measured from the object to the sensor, not the front of the lens. This means the flange focal length (46mm) and the length of the lens itself are included in the MFD.

This is why though the 35 macro has a MFD specification of 14cm, the minimum focus is about 1cm in front of the front element, practically touching.

Yesss, that's right isn't it?! And it's a fairly long lens. So, the measurement is correct. Thanks for the reminder/explanation.

But I hadn't heard many people talking about how close you can get with it. Pretty versatile. I stand by my exclamation mark.

I got a 67mm ND filter and a Cokin holder, 67mm ring and a graded ND with the lens. Also something I've been wanting to try and haven't ever purchased. Looking forward to giving it a rip. Should be a nice zoom/filter combo with the 60-250.

Shouldn't MFD be from the front element, makes practical sense- other wise I've had to all wrong up till now.

As said above, MFD is measured from the sensor plane. Makes it comparable between lenses of the same focal length. The less-quoted minimum working distance, MWD, is measured from the front of the lens.

Got it, now I properly know the terminology. Thanks!
