Thanks. But which is the "the metering gear DOG"?

I find this answer by David Odess in an old thread on overlapping A12:

 

"Overlapping anywhere else on the roll can be caused by any of the

following:

 

1. Sluggishness of the metering gear dog caused by over-lubrication.

Some technicians lubricate this part, but they shouldn't. It must be

clean and free of lubrication to move freely. I have seen many brand

new film magazines with overlapping problems that were caused by

someone at the factory puting grease on this part. Then the film

magazine sits on the dealer's shelf for a while, and the grease

coagulates, causing the dog not to move freely.

 

2. The rivet that holds the dog to the metering gear could be lose.

 

3. The upper drive gear could be worn, even in a fairly new film

magazine. I have seen, in some cases, where there is a burr on the

dog, causing wear on the inside of the teeth on the drive gear."

 

My question is: what are "the metering gear" and "the metering gear

dog"? How can I identify them in the opened A12? Thanks.

It is said that Rodenstock Apo-Grandagon 55mm F4.5 is designed for

120 film. So on 4X5 film, this lens has high resolution and is

sharper than Rodenstock Grandagon N 65mm F4.5. Is this ture? Does

anyone has any experience with these two lenses? Any

information/comment is welcome. Thank you very much.

Zoom lens for Hasselblad 6X6. Yes! If so, great! Say 45-90 F4, strongly needed!

I am using three Nikon AR-3 for my two Hasselblad 503CW and one Xpan. They work OK.

'Quite often, despite taking care to align the lead tongue of the film with the appropriate mark inside the camera body, the film fails to advance and wind through on closing the camera back.'

 

Yes. My Xpan dose the same sometimes. I have shot 1200 rolls of 36 EXPs film with this Xpan from fall, 2001. Now its main switch gets stuck. I have it repaired.

I use 45 mm 50% of the time. 90 mm 50%. The proportion would be 30 mm 10%, 45 mm 45% and 90 mm 45% of the time IF I have the 30 mm which I consider is over priced.

Interested in Markins M20 and M10 ball head. Any experience and

critique is welcome. Smoothness, precision and durability are

concerned. Especially the performance under critical conditions as

long distance travel, cold weather, rain and dust. Thanks.

200 series products have stopped. Bad. Hasselblad should have improved them .

Sorry. And the bad news is that there will NOT be a new 200 body because all the 200 products have stopped producing.

Should be a new 500 series body with TTL metering. And the bad news is that there will be a new 200 body because all the 200 products have stopped producing.

I am interested in the Foba Mini Superball. Any comment on this ball

head is welcome. Both good and bad. Thanks a lot.

1228 and 1277 ball head is ok for 503 and 80. But the 1325 is surely better. My suggestion is 1227 or 1327.

Three of my four A12 backs encountered the same problem. The small

handle grip in the winding crank fell off. So there is only the

plastic needle like axis left. That I have to nip the small needle to

wind the film is hurting my finger tips. Anyone has had the same

experience and has managed to fix the grip back to the crank? Any

instruction is welcome. Thank you very much.

60mm. Easy to use. very good image.

I am now using the Gitzo 1327 tripod + Gitzo 1277M ballhead +

Hasselblad 45144 quick release clamp. On the top is 503CW body or

CFE350Sa lens. This system works fast and well. But in the wind the

clamp and the head seem not rigid enough. So I have been considering

to buy an Arca-Swiss B1. I would like to know if there is an A-S B1

or other product similar to the B1 which has a Hasselblad style quick

release clamp. And is there a Hasselblad style clamp which can be

attached to a ballhead except the Hasselblad 45144? If the answer is

yes, should be very good that I can mount my Hassies directly with

the integrated Hasselblad style quick release plate. If the answer is

no, why? Thanks a lot.

Can a Hasselblad be mounted to Gitzo G1387 Universal DoveTail

Adapter? If yes, that means the intergated quick release plate of

Hasselblad body or lens fits the Gitzo quike release base. Thank you

very much.

I did not use 2XX in winter season. I can just confirm that the 5XX works well above -25 C. For your refrence, one of my friends have been shooting with his Pentax 67 which has a bettery powered plane shutter in very cold weather for many years. The tepm sometime drops to -40 C.

If you mean 0 degree centigrade by saying "freezing point", there is no problem of both center shutter and plane shutter. The problem will take place when the temperature drops to -25 degree centigrade and below with my the Hassy leaf shutters. The limit of the plane shutter depends on how far the batteries goes.

'F801/N8008 cannot drive AF-S lenses'? At least AF-S lenes(not G type) work on almost all Nikon bodies even though without 100% function. The reason of "why don't you just get those Canon products' simply is I already have Nikon system. Canon also dose not custom make products but indeed have more extensive body and lens line than Nikon. As a senior Nikon user I just hope Nikon makes more and good products to meet the customer's need!

Shun Cheung, thank you for agree that 80-200 f4 AF-S would be nice. And I agree that if Nikon makes this lens, it might be G type. But the point is Nikon FM3A is a new model! Nikon just makes G lenses not work with all of the bodies they are making!

The shutter of my F801s has been run more than 40,000 cycles since 1994. What I like to have now is 17-35 and 80-200 zooms with constant aperture(say f4) and build-in silent wave motor(AF-S type). Also with aperture ring(not G type) and must be light weight. F100 is a little bit heavy. A light and cheap Nikon body like Canon 30V which has at least 4f/s driving speed sounds very good.

I have used Nikon system for 17 years. Now have 17(Tokina), 24AF,

60AF M, 80-200AF2.8ED(one touch type). And one F801s, two FM2 bodies.

I am planning to buy new system with AF-S function. I need the 17-35

and 80-200 range zooms and hope: 1,They can be used with my old

bodies; 2,They are light weight. So my dream Nikkors are 17-35 f4 AF-

S (not G type) and 80-200 f4 AF-S(not G type too). I guess there must

be many Nikon users also want to have my choice. Now Canon lens line

just seems to have any lens a photographer may need like the 17-40 f4

and 80-200 f4. To say the body line the situation is the same. The

Nikon does not have a light and cheap body like Canon EOS 3,30,and

the new 30V. Nikon F80? The viewfinder is too dim and 2.5 frames/s is

too slow!

Is the AF-S 80-200mm f/2.8D IF-ED still under production? Thanks.

Yes. CFi 100 is super.
