I agree . The 55-300 doesn't make the cut for FF - I have being shooting with it plenty for little league baseball action.

It is a tough call between the DFA 28-105mm and the DFA 24-70mm for an all-around travel lens, depending on what factors are most important. Since you state you want it good for indoors, so wide is important- that also implies lower lighting, so having that constant aperture of f/2.8 seems like an important factor too, and the DFA 24-70mm does go significantly wider. It also has enough reach for portraits, and the f/2.8 is better for that also. If you ever should do some shooting of indoor sports where you are fairly close to the action, you might find it indispensable, as I do with my Sigma 24-60mm f/2.8 EX DG, which is a favorite of mine for numerous uses.

The minus aspects are its size, weight, and cost. With the hood on, nearly 2 lbs. vs about 1 lb. for the 28-105mm, and about 1" longer, with a filter thread size of 82mm vs. 62mm. But, as always, this is to be expect when going for a pro-level zoom lens having a constant f/2.8 aperture because there is a need for what it offers.

Right now, I see B&H has a sale going on at $200 off of the regular price of the DFA 24-70mm f/2.8, bringing it down to about $97 over the $1,000 mark you are aiming for, with free shipping.

To augment what I've already said, the DFA 28-105mm f/3.5-5.6 will probably perform as f/3.5-4.5 just up to about 50mm. That is, it will hover around 1 stop less aperture than the DFA 24-70mm f/2.8, after which there will be a 2-stop difference out to 70mm. I say this because with my DA 18-135mm f/3.5-5.6, it is good for f/3.5-4.5 out to 70mm, after which the shift to f/5.6 takes place- but it can go out as far as 70mm only because its full range is to 135mm, not 105mm. Also, the 24mm wide end is still very useful for APS-C as well compared to 28mm, which provides no wide angle at all.

The DFA 24-70mm f/2.8 has received an excellent review by ephotozine testing. As to adding the weight, what I do is use a camera/lens holster of a larger size that will accommodate the depth when he lens is mounted. I go cross-shoulders with the case strap, and also use the belt loop to prevent swinging. For a longer tele range, such as the DFA 70-200mm f/2.8, for me that would get to be a bit much if I am doing a lot of trekking, so I simply go the APS-C route for that with my DA* 50-135mm f/2.8 instead.

Thank you all for the responses! I ended up going with the Pentax 24-70 from b and h. Major selling point was the reviews, and 2.8. My second choice would have been the 100wr macro prime with da* 55. But I'm happy with the zoom choice. I already carry cross shoulder so the extra weight doesn't bother me. Super excited!

Hello all!

I need a travel lens(es?) for a trip to the Desert. The ideal lens would be suited for indoor shooting (so wide is important), and just enough reach for portraits. Originally I wanted to go with two primes (135mm + ~20mm wide), but I don't like the idea of changing lenses in dusty conditions. My only issue with the 24-70 is that it looks big and heavy... I can carry a short prime all day long, and a long prime in the backpack for when needed. But with the 24-70mm, I could keep the lens attached through-out the entire trip and not worry about a spec of dust.

Requirements:
WR seals
Autofocus (absolute must)
Full Frame
~$1000

What are your thoughts about this?
I don't get it, you want WR but are looking for fast and wide to shoot indoors, if you are indoors, what is the issue with changing lenses? Am I missing something?

For fast and spwide, I know it is not WR or AF but what about a samyang 14mmF2.8

I love the Samyang, but would need something with autofocus for traveling. Typically I throw the camera to a guide, wife, friends, etc to grab some quick snaps with me in it.

Please let us know how you like your new lens. My guess is you will find numerous times when it is just the thing to fill a need, as time goes on. That has been the case with my old Sigma 24-60mm f/2.8 EX DG.

I've got a shiny new DFA28-105 delivered this morning to be my travel lens. I tried both the 24-70 and the 28-105 on a pre-release K-1 in the Pentax Tokyo showroom last year and decided the 24-70 would get tiring after a full day of lugging it about. I mostly shoot at the wider end so not giving up too much in the way of aperture most of the time.
