My Budget (Amateur) Wedding Photogaphy Setup

I've done a few weddings in the past for friends or helping friends. I've always found them quite stressful, big day, no repeats etc.. One friend asked me to take a few snaps, so I took along my trusty OM2 with 50mm lens, intending to do a few background informal shots only to discover I was doing the lot! I then discovered that the camera was giving me the same meter reading no matter where I pointed it. I guessed all my exposures all day and thanked the latitude of film. They were very pleased with the results luckily and I just handed over the developed films for them to turn into an album but I think that might have been the last time I took a camera to a wedding, from then on I concentrated on drinking the couples health and sparing my own nerves.

I used to do weddings in my youth for some extra money...I started with a Yashicamat 124G and a Pentax MX. On the MX I had a Vivitar series 1 28-85 ( or was it 90) and a 50/1.7. Later I replaced the Yashicamat with a Hasselblad 500C with the 80mm T* and a Kenko 2X. I also got 2 A24 back. For 35mm I upped to a Super Program. I used Vivitar 285 with my own lead acid batteries that got me up to 800 full power flashes. I always used a bracket for the flash. I only did one wedding for a friend with digital...Pentax K2000 with a Vivitar 285 on a bracket. I don't know why someone would think Pentax lacks for flash photography. I saw allot of wedding photographers using 645s back then. Maybe because I don't use all the advanced capabilities of modem flash... A few thinks I can say about wedding photography... Don't monopolize the couple time...they aren't there for you. Get your posed shots done quick...and the usual required shots...cutting the cake, toasts, garter and bouquet, etc. Take alot of candids, tables and the people there. When they look back on their wedding they will enjoy seeing picks of friends and family...not just themselves. If I we're going to shoot a wedding now with the dslr I have, I would take my K-70 with my Tamron 10-24, FA 50/1.4, 18-200 and 100/2.8 macro. I'd prefer a fast 17-50 but I don't have one. And my flash bracket. You can shoot with higher iso indoors, but why? The flash will freeze action better and lower iso will look better. I'd use an umbrella or diffuser on my flash. I have a bracket with a small umbrella. My 2 cents...

I agree with this based on my K-5IIs.

In my film days I did half a dozen weddings for friends and family as the 'official' photographer. When people asked me to do them, I always made a point to tell them I was a hobbyist, not a professional, so don't expect professional results. I always went to the wedding rehearsal to scope out where I needed to stand and when so I wouldn't miss any important shots. I also always asked the minister how he felt about flash photography. Some said 'no flash' during the ceremony itself, but OK before and after. At a recent family wedding the minister told me 'no problem at all'.

I found it very useful to have my flash mounted on a bracket so it was above and to the left of the lens, so red-eye was never a problem.

24 on crop isnt that wide,I have these 2 as well as the Sigma SW AF,all are good.

The Sigma zoom is the cheapest, note the most recent comment compared to Tamron 17/50.All are film era.

What's cheap? $200? $250?

You could find a 21 Ltd for under $250, and it certainly is worth that much - I find it's my default walk around lens for pretty much everything. (Unless it's pouring out, then the 18-135 takes the throne.)

If you can find a used Irix 15 within your budget that might be worth considering. There is currently one on Amazon for $400 but I don't know what that translates to in Australian dollars or what shipping would be. I haven't checked ebay. Most reviews on this lens are very good.

Being retired I'm in the same financial situation as you so I can relate. This year I've been trying to slowly assemble a lens kit of primes for my K-1 and it's been very difficult, even though all of them are used.

Flash exposure using PTTL

This should not be a problem in most cases as long as the ISO is not set very high with the subject very close. The K-5II manual suggests ISO 1600 as an upper limit. Whether auto-iso will respect that upper limit, I don't know.



This also should not be a problem for general shooting as far as the flash portion of the exposure is concerned. If the ambient exposure is set to overexpose, say full sun on the subject at high ISO and maximum aperture in Av mode with the display blinking, the flash will only make things worse.

There is a lot of good advice in the comments above. I can only add that for general shooting, P-TTL requires very little user input and works in all camera exposure modes. Yes, it even works in "B". That being said, there are limits. Those limits are:
  • Maximum flash output too low for subject distance at set aperture and ISO

  • Minimum flash output too high for subject distance at set aperture and ISO

Here is where a decent understanding of manual technique can help one anticipate when and why things don't work. This is also where the camera's P mode comes into its own. My suggestion is to spend some time with the camera's built-in flash shooting a variety of subjects and lighting conditions to build confidence. Once that is accomplished, learning the ins and outs of using the Yongnuo will come easier.

Is P-TTL totally trouble-free? The answer is obviously no. Nothing in photography is totally trouble-free. Here is a list of common causes of P-TTL grief:
  • Poor support from third-party flash, particularly for features such as multi-flash master/controller/slave relationships

  • Flash not in P-TTL mode. It is never automatic except for the built-in flash in green mode.

  • Attempts to use P-TTL when using the aperture ring to control the iris diaphragm. While this is theoretically possible, your camera will politely disagree and will fail over to full flash output.

  • Having flash exposure compensation set (body or flash) and not remembering such

  • Combination of subject distance, ISO, and technique beyond the maximum flash output. This is most commonly encountered when attempting bounce flash with a very high ceiling. Note that this is a general flash concern and not limited to P-TTL.

  • Combination of subject distance, ISO, and technique beyond the minimum flash output. This is commonly encountered when attempting narrow DOF (wide aperture) close-up work. Again, this is a general flash concern and not a P-TTL thing.

  • Pre-flash output is too high for set ISO, aperture, and/or subject distance. This case creates an error condition with the system failing over to maximum flash output. This is a corner case that primarily affects attempts to do high ISO close-up work at wide apertures.

  • Use of KA lenses. Yes, all lenses allowing body control of the aperture are P-TTL compatible and are listed as such in many Pentax body and flash manuals, that for the K-5II included. However, recent guides have a footnote that exposure errors may occur with non-AF lenses. The short explanation is that the P-TTL pre-flash output is tailored for subject distance when that is known. Auto-focus lenses provide an estimate of such through the mount data pin. Without this information, pre-flash will always be at maximum output, resulting in the error in the bullet point immediately above under some conditions with resulting maximum flash discharge. When using non-AF lenses, it is good to be aware of this weakness and scale back ISO or wide aperture on even moderately close subjects when doing P-TTL flash.

  • Problems with master/controller/slave when doing multi-flash P-TTL work. Everyone should try this at least once if they have both a master/controller and a potential P-TTL slave. Setup is complex. I have used the feature on occasion, but prefer manual technique for off-camera flash.

  • Mixing P-TTL master/slave and non-P-TTL optical slaves. Yes, this can be done and can be done with brilliant results, but requires the slaves to be properly configured.

I think that about covers it. ;)

Again, P-TTL flash is pretty easy and transparent for uncomplicated stuff. It only gets strange when the edges of functionality are probed.

I had a problem with a new Yongnuo with PTTL and downloaded/installed their latest firmware. It works fine now.
