Question about Sony HVL-F56AM TTL Flash

1 Answer

My speedlite HVL-F42AM bought for Old Sony A100 fires before the Mirror has time to expose the CCD sensor as I can see the light through the viewfinder during shooting time. Only in Manual mode I fires like a normal Nikon setup that is I see no flash light leakage in the viewfinder. Also pictures are not bright enough as I can make them in M mode with controlled light output. IS SOMETHING WRONG WITH MY DSLR??? Please let me know as all my friends have only Nikon or Canon.

No I wouldn't say there is anything wrong with your DSLR I would think that the flash sync speed is set incorrectly. Each camera model will have a specific shutter to flash synchronized speed.
I've had and used SLR cameras with sync speeds as low as 1/30 and DSLR's at 1/250.
With my studio camera under studio strobes with a shutter speed at 1/60th I do get a slight blink of light BUT, it's the flash duration that makes the exposure.
There is also a difference between a flash made for a film camera and one that is made for a digital camera check make sure teat the flash is compatible with the camera you are using, also check see what the camera syn speed is and set your shutter speed to that. If your camera is equipped with an "M" mode then it also has a "P" mode for program this is a common mode to use flash because the camera sets everything for you all you need to do is compose, focus and trip the shutter. If the exposures are not coming out right then another thing may be a factor and that's the light metering mode (if you camera is equipped) look in your manual there could be as many as four different metering modes, check to see what the manual recommends for flash photography for your camera.

Another thing I use digital flash on my film cameras BUT not a film flash on a digital camera they just don't sync right.

CCD or CMOS senser better ?

Depends on what you want. The Professional mid frame camera's all used to have the CCD sensor, because they most of the time were used in studio environment. The ISO of the sensors is low, but with enough light there is o problem. But now you see the CMOS sensors are so good, the mid frame cameras now move to the CMOS. CCD is good till 100 ISO. CMOS now can work at 1600 and 3200 ISO and still give superb quality.
So for speed (Canon 1D xx and Nikon D4S) they use CMOS and shoot brilliant pictures even in bad light conditions. When you have time (in a studio) and enough light use CCD like Phase One and Hasselblad.
Goto to see what camera's give the sharpest pictures with the greatest dynamic range. You would think the Phase One with the biggest sensor, but till now it is the Nikon D810, Nikon D800E second and then the Sony A7R. position 8 is the first CCD a Phase one. In the top 10, 3 times Sony, 6 times Nikon, all CMOS and only one CCD from Phase one.

I was needing a new flash for my sony a230 camera and I ordered a sony flash from Anyway to make a long story short, they were out of the flash I wanted and said that they had got...

Missed the model number in your comment
the sony appears to have a longer zoom 105, the vivitar 85 the sony has 6 levels, vivitar 5 levels And the Sony talks about ttl control with wireless - which means you can use fully off the camera - if thats really the case I would buy the flash just for that feature - I have always used my flash guns off camera with brackets etc - reduces the chance of redeye, and gives a better effect ..
re price, in my comment you can see the vivitar at a much higher price then the $199
hope that helps a little

Can a canon speedlite 200e work with a nikon dslr ?

The Speedlite 200e was developed to work "exclusively with [Canon] EOS [film] cameras" according to the manual. It is not even compatible with Canon digital SLRs. Most modern (digital) SLRs control the strength of the flash to properly expose the pictures being captured.

The flash will probably fire when used with a Nikon DSLR but there is no guarantee that the images will be properly exposed. Also, the flash is designed to properly illuminate focal lengths of 35mm minimum. If you are using a wider lens (i.e., 24mm or 28mm) the edges of the image will not be adequately illuminated.

Lens cap off but pictures all black. Tested another SD card same thing happens. Black on review on camera and black when put SD card in computer. Camera a few years old and never had a problem before....


Is this a Canon ? If it is, you need to call Canon. You might have a CCD sensor failure.

Take a look at

If it is not a canon (You do not mention the brand) you are still best to contact the vendor. CCD failures can happen accross the board.

If the lens is a removable SLR type, take of the lens and take a photo. Does the mirror flip up at all and expose the CCD ?

Spots on my sensor, any way ''I'' can clean it?

Make sure the battery is fully charged (or use the optional AC adapter).

Select "Clean CCD" from the Setup menu.

Select "Yes" in response to the prompt, then press the center of the controller. After the CCD vibrates for a short while, the mirror lifts.

Detach the lens.

Use a blower brush (NOT canned compressed air) to clean the sensor and the surrounding area.

Reattach the lens and turn power off.

This procedure is given on page 103 of my copy of the A100 manual.

If this doesn't do an adequate job, you can either buy some swabs from a good camera store, or take your camera in and have it done professionally.

Immage not centered and dark corners on pictures

If it's done it on two different bodies than it may be a lens issue(slim chance). Try another lens on your body. Sony also uses a movable ccd instead of moving optic for its image stabilization and may be a bad design and really prone to screw up. I would lean toward a super steady shot problem and the ccd is not lined up right. Personally I've not been impressed with anything sony for a long time, when it comes to DSLRs the only real choices are Nikon or Canon. They own the market and have all the experience and product lines to back it up. In recent years build quality has leaned toward Nikon. I would make sony fix it and then sell it asap before it does it again, then buy something more reliable. Just something to think about.

Don't even attempt it as it's not amenable to DIY repair.

if you have a warranty then get it repaired. if you don't have any warranty left then contact Sony directly as they have a good track record for offering free out of warranty repairs to cameras with faulty CCD assemblies.

Dust inside my d200

The view finder and focusing screen are separate from the CCD sensor. The mirror reflects the image to the view finder until you take a picture. Then the mirror goes up, the shutter opens to expose the CCD to capture the image.

If you have a lot of dust, you should look into a cleaning kit, or have it professionally cleaned. This will show up on your images as white and/or black specks.
