DA 18-55 vs. DA 16-45 & DA* 16-50 wide open

For a kit lens, I had low expectations of its performance wide open.
Perhaps this snapshot was taken in optimal light conditions, but I'm quite pleased with its sharpness wide open (f/4.0) at 34mm. Anyone comment on their experience with shooting wide open on this lens?



This may have been discussed at length previously, so please excuse the repetition. I'd just like to know the significant advantages in IQ that the DA 16-45 and DA* 16-50 may have to the DA 18-55.

The 2mm difference between the 16mm & 18mm on the wide end is quite a noticeable difference. That said, the 18-55mm kit does give decent results (definitely better than Canikon's kit lenses) but can suffer a little light falloff at the corners at 18mm and wide open.

I imagine being a faster lense and higher quality it will definately be extremely noticeable taking photos of people in doors. The difference between the FA 1.4 and the kit lense is extremely noticeable when shooting people and indoors.

Out doors the kit lense does a great job, which is the main reason why I have not purchased a wide angle lense to add to my LBA. I use it for the 18mm, then anything else I would use the FA 1.4, then so on.

I took this with the kit lense the day I got the k10d in the mail (UPS comes at 6sh so it was already dark out). I did not have a tripod so I just left it on a old wooden bench to help avoid the shake for the long exposure. I think the kit lense performed very well.

18mm, 20 sec, f/8 (just crop on jpg right out of camera)

Thanks all for your input.

Simon, your shots show off the kit lens's ability beautifully. But I couldn't compare the kit lens to the FA 50/1.4, Chris. It's just in a different league.

What I guess I'm more interested in is a consensus on the benefits of upgrading the kit lens to the DA 16-45 (or DA* 16-50). I do find myself going to 55mm a lot with the kit lens, but would be happier if the same shots taken at 45mm with the 16-45 came out nicer (whatever that means...)

What IQ advantages does the 16-45 have over the kit lens, especially at wider apertures? At 16mm is there large CA, vignetting or loss of sharpness? That would help me decide whether to save up for this lens as the walkaround/landscape lens.

I'm sure the DA* 16-50 is a great lens, but is it a significant leap from the 16-45?
Thanks for all your opinions.

Ash,

I am currently having similar thoughts regarding the kit lense for wide angle and if it is worth purchasing a new/better? walk around lense. It seems many have found that for under 200 dollars the FA 1.4 is practically the best value/extremely good performance to replace the 50ish mm part of the kit lense. While the wide angle there is nothing really in a sweet price point that offers fantastic, noticeable results. Also, there are a bunch of options going wide for the k10d, the DA* 16-50, the 16-45, 12-24, Sigma 10-20 and the handfull of fixed lenses like the 31, 24 etc. Its a tough call and involves a lot of thought as all of these a priced a wallet or two above what the FA 50 1.4 did for replacing the other end of the kit.

Keep us updated on your decision as I am sure the information will be valuable to the rest of us following a similar path.

I have both the 16-45 and the 18-55. The 16-45 is good indoors and definitely better than the kit lens at the wide end. The constant f/4 max aperture of the 16-45 is useful, esp if you use studio setups. It is a fine lens in it's own right but one that requires putting in some time to understand it's characteristics (mine underexposes a little). Nonetheless, it gives me great results which is one reason why I don't have plans for the more expensive DA*16-50.

Here are some recent shots with the 16-45.

Good point Chris,

The FA 50/1.4 is no doubt a must-have. Didn't take me long to 'feel the need' and buy the lens with money I didn't have at the time. But now I'm at least trying to keep LBA in check.

Dennis, I see what you mean. The 16-45 is a serous consideration, although at more than AUD$500 I have to really save up for something I'm not making money out of...

Ash .... I agree about it not being able to compare with the FA50 ... I have just brought all my FA50 images into work with me ... will be posting many up later on from Xmas (as I got it for Xmas) ... and I can tell you ... it's a superb lens indeed.

The DA 18-55 is versatile in the fact that it is a zoom lens .. whereas the FA50 is fixed ... although with a bit of moving around ... it can be accommodated for many shots.

Making the move to DA 16-45

After doing some research, it's clear the overwhelming consensus on the 16-45 is positive, both economically and optically, and clearly a good upgrade from the kit lens.

A few erraneous negative sentiments on the lens were posted on forums, mainly from Canon users...

But I'm personally convinced, it's worth the cost, but I'm going to look for one second hand - from someone who's upgrading to the DA* 16-50 or the like....

Anyone in that position?
A colleague wants to offload his for a good price ($275) but it doesn't have the original lens hood (can't find a replacement anywhere). So I'll wait for another one to come on....

Cheers.
