Someone should address the use of a TC on the 55-300 or 18-135. It will work fine on any of the DA*s but I don't believe I've seen examples on a lesser quality zoom. I know the TC works great with the DA*60-250, which coupled with the DA-18-135 is my normal walk around kit. I take those, and whatever primes I feel up to carrying. The 21 ltd and 40 XS are favourites, because they are so light. I almost always take my FA 50 1.7, for low light situations. A DA 50 1.8 is a cheap alternative and a DA 35 2.4 is also a nice cheap "standard" lens, though it's not as fast.

Anyway, I've post lots of images in the thread below.

And a few more here.

FA 31 Ltd will do those jobs nicely.

I think picking one to do both duties is sort of impossible - maybe something like the DA 35 2.4 (or FA 31 if funds allow) for close ups INSIDE the ship (anywhere you need DOF control or are dealing with low/artificial light) and the DA 18-135 for just about anything outside save for EXTREME telephoto shots?

I don't think there's a great 18-300 f/2.8 zoom for Pentax - otherwise you could always try super high ISO shooting with the 18-135 and embrace the noise

PS - I agree with Norm and wouldn't recommend the TC for variable aperture lenses. Focusing is painful

The k3 is pretty large, are you sold on that? There are smaller weather sealed bodies, some of which allow AA batteries to be used if needed which could be very useful.

I would think weight and size would be at a premium, and push you towards light equipment. If that is the case then the DA 20-40 f28-4 is another option to consider. And maybe a

If size matters aren't as big of an issue, get two k3's, mount a 16-50 f2.8 on one body, and either the 50-135 f2.8 or the 60-250 f4 on the other body.

If you were forced to pick only ONE (weather sealed or not) for taking both close ups inside the ship as well as long photos of distant shorelines then what would it be? I suppose I could always crop the photos later on as long as the image was sharp to begin with. ...
Single lens solutions:

Weather-sealed - Pentax 18-135 mm
Non-WR - Sigma 18-250 mm.

Didn't notice the one lens question. How dark is it inside? Either the 18-135 or 16-50. The difference comes down to better lighting vs more cropping.

The DA* 16-50 wins if I have to pick only one. That's the widest weather-sealed lens, making it good for below deck images and but enough zoom range to be servicable above decks. The extra 2mm width (compared to 18-whatever zooms) is more significant than the numbers suggest.

The 18-135 would be a close second. It's weaker for interiors and low light, but gives you more reach above deck. The 18-135 is also more compact than the 16-50. Other all-purpose weather-sealed zooms include the 18-55 WR (most compact, worst image quality) and new 16-85 (haven't read a review yet).

If you bring multiple lenses, then you have more options, but I think you still want to base things around the 16-50 or 18-135.
  • DA* 16-50 as your main lens, with something else to fill telephoto needs. The 55-300 would be a good pairing because it's compact and relatively inexpensive.
  • The 18-135 as your main lens, with something wider for interiors. The DA15 is a great lens and very small so you're less likely to bang it into things below decks, or maybe use an ultrawide zoom like the Tamron 10-24.
It's easy for us to spend your money. What lenses do you already have?

if price is not an issue get the 18-135 and the 60-250+TC. Otherwise instead of the 60-250, go for the 55-300, skip on the TC and get a decent prime instead for some vessel interior shots.

This is what I was going to recommend, and DeadJohn beat me to it.

I tested this for backup. Just put the card in and let it sync. 16 GB takes 20-25 minutes and to make sure it worked you can connect to it via wifi.

The HD DA 1.4x Rear Converter does not work optimally with lenses of maximum aperture above f/4.0
For a maritime environment I would go with the DA*16-50, DA*60-250 and (maybe) the teleconverter. And a flash for interiors.
I would buy a good 77mm circular polariser (and maybe a 67mm as well) and no other filters. The DA* lenses have very tough coatings on the front elements and do not need protective filters.
SanDisk Extreme Pro cards are excellent.

Thanks for all the replies everyone! I am doing lots of research into the options and looking at all the suggestions. Here are the autofocus lenses I have now. I am not including the manual focus ones because given the limitations for what I can bring I'd rather pack autofocus lenses.


Promaster 28-200 f/3.8; Sigma 18-50 f/3.5; Sigma 28-80 f/3.5; Sigma 30-300 f/4; Takumar-F 70-200 f/4.


As far as the teleconverter goes I am impressed with the results with the 60-250. Those look sharp! That would give me a lot of range as well. As far as the size of the K-3 I am happy with it. I considered getting one of the WG weatherproof cameras and using that for extreme situations and then using the K-3 for the milder weather situations aboard the ship. That would alleviate the need for a shorter focus lens outside the ship. The inside of the ship is not that dark. It's no darker than the average household with a 75 watt bulb to light the room. If the choice comes down to the DA* 16-50 or the 18-135 I think I'd choose the 18-135 because if it gets damaged I'd be willing to live with that loss. The price of the DA* 16-50 isn't a concern but I would just feel like crap if I dropped it by accident and the lens cracked. Everyone makes stupid mistakes and I know I could live with losing a $500 lens rather than a $1,300 lens. I am genuinely interested in getting the BEST lenses to travel with but I also have to factor the possibility of some stupid incident destroying the lens or rendering it inoperative.


I should also mention that I did use a circular polarizer for many shots aboard the ship when I had my Canon S3IS. I found it very useful and I should consider bringing one along. I have several of them and I'll test them out with whichever lens I grab. Filters are easy to pack and I know I could bring a dozen if necessary. I like the results with the Hoya filters so I'll stick with them unless someone gives a better suggestion.


Thanks again for the advice! I am digesting all of it and taking all the considerations seriously. In the meantime if anyone has photos taken at a pier or harbor they would be willing to share then that would be greatly appreciated. I found that the high contrast shots of ships are very difficult with the sunshine reflecting off of the water.

I don't know why no one pointed you here: https://www.pentaxforums.com/forums/attachments/137-photographic-industry-pro...fghanistan.pdf

Our own Heie has spent significant time in Afghanistan with his 2 Pentax cameras one with 16-50 and the other with a 60-250. Maybe PM Heie, he's bound to understand your specific situation more than us.

One lens? Certainly not the mediocre 50-200. It would be the DA*50-135. It's a compromise in focal length between near and far But.......gives you an F2.8 for inside pics. Images will be comparable to a prime lens. Otherwise I would have chosen the 60-250, but it's F4.

When I get off work this evening I can give better ones taken into a sunset, but this is one I took with the K3 and 18-135 WR in Rotterdam last week. It has been cropped too.
