Not sure if this is the right place to ask.
D40 - works find with AFS18-70. But got problem with my old Tm28-200. After mounting it, error message asking me to turn aperture ring to F22. At F22, error message still there. Only got this problem like a week or so ago, when previously, it was working fine. Went to Cam Hospital and asked Steven. He said some interface problem and cost like 100++ to fix. Not sure if I wanna to repair.
Anyone got this or similar problem? Wonder if this is a common problem or just that I got A** luck.
Thanks Isisaxon for the reply. At the cam Hosp, Steven did try on a few of his lenses and confirmed that it is not due to third party lens, but the interface cannot read those D lenses, but OK with G and AF-S lenses. BTW, I have used my friend's 85mmF1.8D lens and worked flawlessly earlier with MF.3rd party can never predict how Nikon structures the data used on their electronic interface. So they most they can do is do reverse engineering to find out. What they did to obtain how the lens should 'talk' to the body at that time may not be the entirely correct language/protocol, so with newer bodies they may not fully understand each other. Same goes for flash and other accessories which requires electronic communication.
There is nothing wrong with the interface just that it requires a new chip which is more well behaved that can 'talk' properly with the new body. So that's probably what the $100++ would be for.
Thanks Simon for the prompt. Will call NSC tomorrow and ask them and ask for a quote as well. Likely for info only as I am unlikely to send for repairs.La Fontaine, you can called up nsc to enquire about this problem with the technican over the phone and do ask for servicing quotation as well.

too bad for me i forgot about the "Carl Zeiss" glasses.
Carl Zeiss Planar T*50mm f/1.4 Nikon mount can be bought with a very affordable price of S$19,745 :bigeyes:
Quite cheat!!

Edit: Yup.. Just tested.. The tab is used to tell the camera that the aperture ring is already at the minimum aperture via a tab on the aperture ring. Maybe the tab on the lens you used is damaged or the plastic wedge on the body is damaged?
Thank you very much, Isisaxon. Really appreciate it for all your effort. I will go back tonight and check it.
Any luck?
Hi Bro Isisaxon, have been very, very busy and didn't have time to check it.
Checked liao. Yeah, it is the plastic tab in the camera that is damaged by a lens. Went to NSC to ask them to check. To change that tab, it cost a whopping $100 for parts and labour.
So, just live with it la. So, if I wanna to use a D lens, just have to be careful and manually push down that tab.
Or, if I got time, I might wanna to try filing and smoothen down the tab to see if it works. I will report back soon.
If you're game enough, you can find a small piece of plastic, glue it on the broken tab and try to sculp the excess off to form the correct shape using a hot knife (so that you will not generate plastic debris). It will take some steady hands though. Another option is to use epoxy and build it up to shape slowly layer by layer like how dentists do cosmetic filling for front teeth.
On this National Day, I did a little DIY in the morning.
Using some fine sandpaper, wrapped over the file of a nailclipper, I got the wedge shape tab of the D40 filed down to smoothen the surface. Tried with my old Tamron28-200 lens, it worked. Noticed that the wedge tab is now grey in colour, I got a marker pen to colour in back to black. Then, to make doubly sure that it is smooth, I applied a little Singer oil on the surface. So, this time, it is really smooth and flawless. And my D40 is now working like perfect.
As I got a bit more time in my hands, I did some cleaning of the lens mount as well, both the cam side and the lens side.
I don't think the Sigma 50/1.4 HSM is out on f-mount yet, but the Canon version is already out here in Japan. It's about 650++ SGD. I don't expect the Nikon F-mount version to cost any less, unfortunately.
That places it way over the Nikon 50/1.4 - bad news for us D40/40X/60 users hoping to get a 50/1.4 prime with AF compatibility at a "happy" price.
Anyway there are a few third-party lenses more expensive than Nikkors on the market. Look no further than the Carl Zeiss lenses on F-mount. Hehe.
sorry guys, im quite a noob. so if Sigma 50/f1.4 HSM is not out on f-mount, we can't fit it on the d40 right? :sweat:
also, any idea if this Sigma 50/1.4 HSM lens can auto focus on a d40?
And since all Nikon DSLR support HSM (I think confirm please) YES it will AF on D40/X & D60.
It's not for Nikon to support HSM.. It's for the 3rd party makers to make their lenses to be compatible with the camera manufacturers. Nikon does not need to be responsible if 3rd party lenses don't work.
