Will lens from a sf1 fit the newer models like the Kr or better

besides being a old model, you also must think about getting
parts for the machine if that becomes neccessary.
and sometimes parts are hard to come by and some times there
are no parts.
it would be a better idea to get a newer model sewing machine, one
that is being sold by the elna agency in Africa, that way there
should be a better chance of getting parts.

It is not worth repairing at such a cost as it is bettter that you can buy a newer model with an extra bit more. Also sometimes it is possible to get the spares freely from a repair store from a camera which was scrapped for a optical failure.
So until you get one for a cheaper cost the best option is to buy a newer model with better features. Some companies are taking old models for an exchange and this must also be checked .

Looks like you are in luck:

Hi ericm675, Yes they will. What you run into is were one uses a auto focus lens on a newer digital such as a D40. Some of the new digital cameras do not have the drive gear to turn the autofocus on the lens. Those newer cameras use electronics. Look on your camera lens mount at 7:00 you will see the drive pin. Look on your old autofocus lens you should see a slot where that pin fits. Hope this helps you.

In most cases, the camera is beyond economic repair. If the camera is a few years old, buying a newer one is a better option. I'm seeing brand name 10 MP models NEW for $60. you might check online auction sites for used ones. I've picked up 5 MP ones for $5.

The #4 Little Chief element is 7 inches and more importantly is 250 watts, this is the correct wattage for ALL Little Chief Smokers newer than about 15 - 20 years old.
The #5 Little Chief element is 8.5 inches and is also 250W but is for newer models before 2006.
Look at www.smokehouseproducts.com for clarification & best fit.
For very, very old models (20+) there is a ceramic disk (175W) that heats the chip pan and is hard to find and expensive, a person would be better off finding a new one on sale at the big box boys store

prasadsu,

any camera store will have a flash for your KR5. buy a non dedicated type that fits on the hot shoe.
or try ebay for a used one.

Sunil, there's a huge array of flashes that will suit that camera.
What you have is one of the old-faithfuls of the camera world. Not over-the-top glamerous bits, just basic necessary features that work well, and that camera will go for a long long time.
The hotshoe, the 'slide' on the top of the camera that accommodates the flash, is NOT a 'dedicated' shoe which means there is no auto or specific links between the flash and the camera.
You need to talk to someone over the counter because models of flashes are changing every day and I do not keep up to cover them all.
What I would be asking for is firstly, a hotshoe flash, then, an auto flash (this means the flash itself will meter the light output and adjust itself), then you want to buy a flash for its power output (guide number) don't waste your money on useless features for that camera, put the money into to flashes power, higher the guide number the better (GN20 is low, GN30 is good, GN40-45 is very high and likely a huge flash).
So, and auto flash, not dedicated, no fancy features, good GN (high 20s-mid 30s)
Also, don't buy brand names (ricoh, canon, nikon), pointless in this case. Look for generics, Metz, Sun, Sigma etc.

Yes the mz-7 Definitly uses a K mount.

You didn't state whatbrand of camera you have. Nikon, Canon, Pentax and Minolta all make digital cameras that take their old lenses. In the case of Minolta, Sony took over the production. The only things that may not work are the old flashes. The new digital cameras may need upgraded models of the flashes. Never use an old flash on a newer digital model without checking if it could damage the camera. You need not buy a 12 mega pixel to print 4X6 prints. Their older and less expensive models will work just fine.
