Nikkor 60mm Micro

Anyone has try 60mm + Kenko´s TC after upgrading the firmware on a D300?

I did: no problem!

Hola compadre, I tried the brand new out of the box just arrived yesterday kind of D300 from my local dealer and with the Kenko & AF-S 60mm its was "una chinga" no way jose!. I dunno if it was the latest firmware, but I presume it to be, Claude you say it work????, OK now i'm confused, (what else is new), was it the new AF-S version (no aperture ring) or the older AF (with the aperture ring).

BTW Felix you have to stop trying to roll your SUV on its roof, you'll end up scratching the paint one day as I recall, the manufacture recommend keeping all four of wheels on the ground.

Claude you say it work????

ooopss... sorry... confused: I'm speaking about the AFD!

Hey my dear friend, I ask this because when I tried mine on the D300 I got a blinking battery as if were dead. The new firmware supposed to fix this "battery blinking" issue, but I had been to lazy to upgrade the firmware, and if this won`t fix the 60mm + Kenko issue, i see no point on upgrading the firmware. I guess is the lens not the camera.

He, he, he... it doesn`t came with a "this side up" arrow, so...

Now talking seriously, this road trip was amazing, it was to some river caves (no diving) a few hours down from where we dive in "Morrocoy", I`ll tell you all about it later to stay on topic here...

Hugs to Beatriz.

f32, f57? I'm trying to understand something in Ken Rockwell's review of this lens. He says,

Diaphragm: 9 rounded blades, stopping down to f/32. It's remarkable: it really stays round! At closer distances the lens becomes slower and it can stop down as far as f/57 at 1:1.

I understand about rounded blades, and it stays round. But it stops to f/32, AND stops down to f/57??? How can these both be true, on a fixed-focal length lens?

If someone could recommend a text that explains these kinds of points about lenses, I'd be very grateful.

Tubino,

While it is a "fixed focal length" lens, this doesn't hold true when you use it in macro mode. In order to focus closer, the front element has to move further from the sensor effectively increasing the focal length. As f/stop is the ratio of the focal length over the diameter of the aperture, an increase in focal length while keeping the aperture the same results in a larger f/stop.

Nikon displays effective aperture, not actual aperture. At macro focusing distances, effective aperture is smaller.

While the lens does vary its focal length with focus distance, that's not the reason why effective aperture changes. Macro lenses typically shorten with close focus, not lengthen.

This makes sense to me -- in the case of a lens that changes physical length with focus (like my Tamron 90mm macro). But since this lens is internal focus and does NOT change length... I still don't get it. But I'll read the links Craig provides and see if I get it then. Thanks!

It does, you just don't see it externally, the fact that it it is internally contain does not change the lens must reposition its element to focus closer.

Okay, I'm starting to get it now. THANKS for those links! I'm still trying to look at it from the different ways... it's one of those many things that don't quite add up until you can hold several parts of it in your head at once, AND how they relate.
