Promaster 7500EDF Flash

somethinchill · 07-08-2009, 10:25 PM

I just bought the Promaster 7500EDF flash for my Pentax K20D. If I use the flash on PTTL/Auto, what settings should I have my camera on for a wedding? Indoor and outside, evening and day. Thanks.

I am actually curious too about this flash.
Could you post a review once you have gotten the hang of this?
Thanks in advance!

somethinchill · 07-09-2009, 05:58 PM

Sure no problem.

Broad subject.

First off, what kind of lenses will you be using and is this wedding all indoors, or half in and half out?

Also, no one has seemed to gived this flash a review ( I checked on a Google search). Can you review it for thye forum members here?

Give me the equipment info and I will give you my guidelines.

GerryL · 07-10-2009, 01:10 PM

res3567, I think this might have some similarity to the Vivitar DF 383 that you recently purchased.

somethinchill · 07-10-2009, 06:51 PM

I have a Pentax SMC DA 18-55mm. The wedding will be indoor and out side.

If that is your only lens, then shoot in AV.

The flash should compensate for whatever apeture you choose. Shutter speed will change according to the zoom of the lens per the flash communicating with your camera. It will stay locked below 1/180 sec.

Indoors I would use ISO 400. This will save power to your flash as it will not have to use a lot to get the proper exposure. The K20D has excellent noise suppresion at high ISO's You could probably use ISO 800. I have a K10D and 400 is what I use.

Outdoors you can set your ISO to 100 as there should be plenty of light in the daytime and evening.

As for RAW or JPEG that is your call.

WB should be set to flash.

That is pretty much it for camera settings; that is what I use for weddings.

If you require more info on how to shoot a wedding, I responded to a thread a while back. Let me knoe and I will find it for you.

I just answered your basic camera settings question and I hope this helps.

somethinchill · 07-14-2009, 11:22 PM

Unfortunately this is the only lens that I curently have. I am saving up to buy a better one, do you have any suggestions?

Thanks for the help.

It would be great to get the extra wedding info, if it's not too much trouble.

I read a comment that the Promaster 7500 on a K20D owner was giving him/her exposure problems.They were saying that it could be a problem with the connection points between the flash unit and the camera causing this,not connecting properly.Whether it's true or not I can't say,but just out of curiosity,I would like to know how your new flash goes after you have given it a good run,and whether you encounter this exposure problem.I'm looking at a few different brands,so this would help me on whether the Promaster brand would be a worthy buy.

First off I must say that flash photography is not very easy.

I did not see the post about the settings until after I tried using the flash. I took some great photos and then I took some that sucked.

I need to get used to the different settings that the flash and camera offer. I had no connection problems. The only problem was that the hall where the wedding was was super dim. The best pictures came when I would bounce the flash off of the celing. After editing the photos and lightening them up a little, they looked great.

I will keep everyone posted as I continue to play with the flash.

Can you please tell us what mode of the flash (P-TTL? Auto? Manual?) you used?

somethinchill · 07-16-2009, 10:53 PM

I used it in P-TTL mode.

That may be the reason. I'm not happy with Pentax P-TTL (K10D body + Pentax 540 flash). Direct flash results in inconsistent exposures. Bounce flash is better (but not as consistent as auto mode).

Does the Promaster have 'auto' mode (measuring light using its own sensor)? If yes, try auto mode to see if you get better results.

GerryL · 07-17-2009, 05:00 PM

How's the AF assist of the flash?
Is it better than the strobing flash of the camera?
Does it AF faster in dim light?

Lenses for weddings is such a broad subject; but here are the basics.

Money. How much are you willing to spend?

Two good zooms will cover most of your shots.

I would reccomend the Pentax 16-50, and the 50-135.

These are quite expensive as a pair; well over $1000.

There are cheaper alternatives, however.

What is your budget?
