Doubtful.

I paid around 55 for a mint WR version.

Not the best lens around but for that price it's something worth having. Certainly not worth the price it goes for new.

I also have a 44 and it works fine. Not the most powerful flash but well built and certainly powerful enough for most situations.

Now back to €310, but number one in sales in DSLRs (no surprise there).

Wow. I had a quick go with a K-S1 before I bought my K3 and it's a nice camera.

I bought the WR version earlier this year to have a smaller long zoom than my 55-300 but I wasn't very impressed with it. I found I usually had to stop down to f/11 to get anything decently sharp. I did get some nice photos with it when on holiday in the US in the summer, despite the lack of resolution.

On Amazon, seems like a decent price.

I've done this in my own office and have a few things to comment that I think will help.

1. Use as small a lens as possible. Big lenses (and cameras) are intimidating. I found the DA 70mm ideal for this purpose.

2. If someone really doesn't want their photo taken then don't force the issue.

3. Have a "helper", even if they do nothing more than ask people if they're willing to participate. This will help create more of a team spirit and make you appear less like just one guy doing a task and more like a team organising a fun activity. If the helper is an extrovert and knows everyone then much better.

4. If you use a flash then make sure it's bounced off a ceiling. You'll probably need to go to manual mode if you only have vintage units but within an office it's unusual for light to vary drastically. Unless you have really good natural light available then bounced flash is the best thing for improving overall IQ.

5. Show the people the photos straight away to make sure they approve. Do a good job and they'll be glad they chose to participate.

6. Make your workflow as fast as possible. Get your settings right and shoot jpeg for speed and to avoid the temptation of PP'ing every photo. This will depend on the numbers though - I did this for around 130 people and had to get them to a computer, arranged four to a sheet of A4 and printed, all in the same day. If you're doing fewer then you may have more time to retouch.

7. I printed something akin to contact sheets with file names so that people could identify their own photo and I could send them the original for their use. Many ended up as intranet ID photos at work or on facebook or linkedin.

I've used this method for ages, that's what the two-second delay is for.

I'm still using the version I got for that price a few years ago in the BF deals. I think I might need to upgrade the laptop before getting anything significantly more powerful.
