All are relatively easy modifications.

I'm back in Oslo in a few days' time and will start looking at incoming orders then.

Then next week I'll start pestering you with my order for specific lenses.  So far the list is:

16/3.5 - gotta try to put one on at least one of my copies.  Need to find a wrecked 16/3.5 AI that I can use for spare parts.
20/2.8
105/2.5 AIS
135/2 AIS
135/3.5 AIS
300/4.5 ED AI
400/5.6 ED AI

I will finalize it next week in a PM to you.

I have calculated the new prices of CPUs. The price is for a CPU unit customised and programmed to a specific host lens. You get a warranty of the chip for 5 years, subject to it being properly installed and replacement stock availability.

For NG Supporters, it'll be USD 35,- each. Payment by Paypal only, no personal cheques will be accepted.

For non-NG Supporters, it is USD 55,- if you wish to become an NG Supporter (USD 20,- is then transferred to NG as part of the deal) and any additional CPU is priced as for NG Supporters. Alternatively, USD 56,- if you prefer not to enter our support community.

Shipping USD 5,- world wide for CPUs. You can combine more CPU items in one shipment and pay only shipping for one of them. In the case of ordering other hardware, shipping expense is set per case so just ask beforehand. Items are shipped by air mail. If you require registered post with tracking, this will be USD 50,- (Norwegian Mail pricing applies).

As to mounting hardware, I recommend you source this from eBay sellers or USCamera.com, or get wrecked cheapo kit zooms. I can supply original Nikon contact blocks, silver pins, or mounting screws, but these parts are pretty expensive and back order delays will occur if I haven't them in stock. I sell then on a net cost basis meaning you get the hardware for the exact same price I pay Nikon myself.

Any questions of how to implement the CPU can be asked and answered here on NG, either by me or other experienced 'chippers'.

Thanks,
Bjørn

I have new stock available.

28/2 and 105/2.5 are easy, 50/1.4 is doable, and the 50/1.2 is a challenge even for Dr. Lens.

Bjørn,  I have some pre chipped Nikkor lenses, not sure how to define that.  ;)

In order of focal length:

55mm f 2.8 Micro #281115 (minimum aperture f32)
105mm f2.5 #677139 (converted to AI by filing a gap on the periphery of the mount) (minimum aperture f32)
180mm f2.8 #376338 (minimum aperture f32)
300mm f 2.8 #605808 (minimum aperture f22)

In order of usage:

55mm f2.8 Micro (one of my most used lenses)
300mm f2.8
105mm f2.5
180mm f2.8

Do any of these lenses present any particular challenge to add chips?

Will any of these lenses benefit more from chipping than others?

I am trying to prioritise, I can't afford to chip them all at once, maybe even not all of them at all.  After all they take good images as they are, I see it mostly as a convenience thing and I  can manage the inconvenience. They are mainly used on D300s and D200, (inc. IR and UV variants) I am planning a D3 later this year.

All of these are quite easy to modify.

Bjørn,

How do I go about ordering the chips?
I'll skip the 50 1.2 for now, but would like to try the 28/2, 50/1.4 & 105/2.5.

Thanks,
Bjørn

If you were going to chip a PK-13 extension tube, how would the chip be programmed? Would it still be programmed as a 55mm f/3.5?

Depends on how you intend to use the PK-13.

For the 55/3.5 as a host lens, effective aperture would be f/5.3. Thus, I would have set the CPU to f/5.3 and 55 mm focal length.

(Edit: the correct effective aperture is f/5.3 not f/5 at M=0.5. Blame my failing memory and being stubborn enough not to check a figure by recalculating it !!)

Is the Medical Nikkor 120mm doable?
