"Sb-28 vs Sb-50.. any thoughts?"


CA
          

The SB-28 is packed with lots of great features but the Sb-50's price is way more attractive. Any thoughts?

I also like the ability to use the SB-50 with the Camera's popup falsh simultaneously. I want to learn to use bounce flash but not necessarily to the side. Just up.

Any one else have thoughts about this?

The SB50 does not seem to be a lower priced alternative to the SB28. It was apparently designed to be used with the N80, by someone who has some flash experience and knows how to get the most from it. There are less expensive third party flashes with more raw power, and similar features to the SB28. If you want to stick to Nikon, consider the SB22s or a used SB24,25,26.---scott

It may not be an exact alternative but it has bounce capabilities. It also allows me to use my F80 popup flash simultaneously. In addition, in Canada, it is $170 less than the SB28. List price of $499 for SB-28. $329 for SB50. That seems like a lower priced alternative to me.

So you are suggesting I don't get this flash? ANyone else have thoughts on this matter? i would appreciate more input thanks!

It depends on what you want to accomplish and what photography you do.
Consider Guide Numbers: the SB-28 speedlight has a GN of 138 (at 50mm, in feet); the SB-50DX has a GN of 72 (feet) at ISO 100 when used as accessory. Guide Number of 82 (feet) when used in combination with the built-in speedlight on a N65 or a N80.
On the other hand, the SB-50DX provides the flexibility of a slave. The SB-28 has to be used either with an off-camera cord or on a SU-4 control unit for creative lighting or on an alternative non-OEM slave unit.
Prices: SB-28 $310 (USA), $275 (Imported)
SB-50DX $180 (USA), $160 (Imported).

I guess something got lost in the translation. Granted, the SB50 costs less than the SB28; I meant it's not just a stripped down, lower power unit for those who cannot afford the SB28. That is more or less what the SB22s is. The SB50, it seems, is intended for a different type of user, and just happens to cost less than the SB28. If you have the F/N80, and want an accessory flash to use with the built-in, then you are the intended user.---scott

Hi Scott,

I see what you are saying now. So is it time to look at other alternatives such as the SB22s and 3rd party flashes such as Metz or Sunpacks?

Hi JRP,

Thanks for the Info. I don't see myself needing any off camera type of flash. Actualyl, what exactly is a slave?

The 138 GN looks great but the 72GN/82GN is already miles above my 12Gn with my pop-up. I am amateur and I don't see myslef needing such a high GN.

So now it's time to decide between the Sb50 and 3rd party falshes right? SUnpakc or Metz?

Hi Jrp,

Why would u not consider a decent 3rd party flash? I am curious.

Go to the B&H website, and spend an hour looking closely at the Nikon-dedicated flashes of all brands. Pick one that has EXACTLY the features you need, such as bounce, tilt, manual settings, whatever. Look at guide number, price, and whether it needs an extra-cost "module". Then go to photographyreview and see what people say about your selection. Remember, "build-quality" is usually a subjective aesthetic evaluation; I know of no site that has statistics on failure rate or breakage of various models.---scott

My first inclination would not be for third party or non-Original Equipment Manufacturer's equipment due to my accumulated bad experience with them. One notable exception is the manual Vivitar 283 of which I keep several.
I wait until I have saved enough to get the real thing.

Just a simple correction about guide numbers.

The SB-50DX has a GN number of 72 at 35mm and the built in flash of the N80 has a GN max of 39. So adding both GN numbers equals 82GN.

If you look at the specs of the Sb-50DX, it shows that the GN number at 50mm is 85GN so if you add the GN of the N80 it goes up to 93GN.

Calculating the GN of two or more speedlight goes like this:
Square root of ((GN of first speedlight)^2 + (GN of second speed light)^2).

^ means square of.

Frank

Looks like a sort of Pthagorean Theorem for flashes. I'm adding that to my little notebook of formulae. Thanks.--scott

P.S. Another way to write "square root of X" on a keyboard is "X^.5"

And to think, I thought 'square root of X' was simple enough rather than cryptic symbols.

Aha! Can we gather then that
Total GN = Sum of all (GNi) {from 1 to n), each to the 1/n power for an n number of flashes?
(Sorry, cold not get the right symbols to show here)

That's a good question, JRP...for THREE flashes, do you solve for the CUBE root of the summed squares? I, for one, am trying to learn something here. Thanks.---scott

Too hard to read, let me try, here is the correct formular:

(for n flash of guide number of Gn1, Gn2, ... Gnn repectively):
combined GN = square_root (Gn1*Gn1 + Gn2*Gn2 + ... +Gnn*Gnn)


---
if all the flash has the same GN, then combined GN = square root of N (where N>1), simple to calculate, you need 4 flashes to double the GN

Nope. I just checked on the formula.
The aggregate GN is always the square root of the sum of each flash GN squared.

#19. "Experience with: Sb-28 vs Sb-50"
In response to Reply # 0



          

I have an N80. I bought the SB50DX. I shot 3 rolls of film and also played with its' built in slave feature. I shot with my Tamron 28-200XR and also one roll at night with a 50mm 1.8f (which is a pretty fast lens). I was not happy with the results. I am sure that is due partly to my own inability to get the most of out my equipment (being somewhat of a beginner), but people were not properly iluminated that were 15 feet away. I returned the SB50 and bought the SB28 (and the SU4) after just a few rolls with the SB28 I can clearly see the difference in the power of the flash, not only in the subject (people) but in the eveness of overall lighting too.
I did not have great luck using the SB28 as a slave with the SU4 so far- if you want to read more about that, it was in a previous thread (which I never got a good reason for why the TTL did not work properly)
Also I am a firm beliver that its more knowing how to use it than what you are using. I have lots to learn .. .. ..
