Why ask us? You are the one taking pictures.

Well, OK, tell us what you want to shoot at least. You are going to get 9 opinions about those lenses, anyway...

I think you have to ask yourself what you will be taking pictures of most of the time.

I have the Pentax DA 16-45mm F4 and a Pentax SMC-M 50mm F1.7.

Which one would I buy? Both. They both have their special uses, and I use one or the other depending on what I want.

Since I tend to shoot a lot of wide angle shots, I bought the DA 16-45mm F4. Great for outdoor shots, and a decently wide angle for what I do.

I have many other lenses (see my signature) and will put them on depending on what I like to shoot. On occassion, I may just put on my DA 40mm Limited pancake lens and take pictures.

I'm with SpecialK on this one. Tell us what you want to take pictures of most of the time.

Maybe i will buy them all in time. The problem is that i have to choose 1 zoom and 1 prime for now for my budget.

Another option you might want to consider is the Sigma 17-70/2.8-4, as it covers just about the whole range that the 16-45 and 28-75 covers. Here's a link to pbase.com where you can see some image samples taken with this lens.

As for your prime, as to which one you should go with depends on whether you prefer to shoot more wide (35mm) or nomal angle (50mm). If you can afford it, the 43/1.9 Ltd falls between the 2 and is also an excellent lens. Here are some sample images taken with this lens: Pentax smc P-FA 43mm f/1.9 Limited Lens Sample Photos and Specifications
Since they're all small apertures, they'll do well for any low-light shooting you may want to do.

Ive had/have all of those except the 35 F2 but I know that is a great lens just by word of mouth. So I can safely say, BUY THEM ALL!!! First I would get the Tamron 28-75mm, it is a great great great all around walking zoom lens. Then I would get the 50mm f/1.4, that would give you a solid prime lens to work with when you want to get creative and really explore photography [sorry I do not know your exprience with photography].

From there you can branch out in either direction, wide or tele.

In this case, I'd go w/ the DA*1650 plus a DA70. That'll make a good combo for most work

I thought Fa 35 f2 would be a good prime for microstock or book shots. Nice to have f2 for subject isolation and it is a light prime to own. (Only if this is the only intention you need with photography)

I thought the OP wasn't taking photos of a book or microstock but photos for them?

Oops, my bad ... The issue with working 48 hours straight ...

Then your suggestion Da * 16-50 and Da 70 sound a great combination

Definitely...

...the 16-45...because I'm selling one right now in the marketplace.

Seriously, though, on the zooms, they are both great. Personally, I would go nuts if I could only get to 28mm wide, but the Tamron is an awesome lens. I'm selling the 16-45 because I want to go even wider and there's too much overlap with both lenses. The 16-45 is a perfect walkaround lens, wide for tight spaces and long enough for most other things in a city walk. Good for landscape too. And lightweight. Some think it rivals Pentax primes in IQ. I couldn't speak to that as I don't own primes. I don't think you can go wrong with either, but I'd recommend wider first.

The 16-45 has very high resolving power as well. Not as good as the 16-50 but then it doesnt cost twice as much and grabbing a good copy is not like winning the lottery. Its also a very solid performer with controlled lighting situations like product photography. Also look at the Tamron 90 macro as an alternative to the 70, more reach if and when you need it, relatively fast or at least the same speed as the 70, cheaper, and just as sharp plus its a true 1:1 macro for those times you want to get real close for stock photography.

thanks for your advices !


The sigma 17-70 has a great zoom range , its true!

I saw some sample photos and it seems to me that the sigma 17-70 is not as sharp as tam 28-75 and as the 16-45 , am i wrong?

The 16-50 is out of my budget .

The 43mm seems a very good prime , but do you thing it will be a better portrait lens than 50mm? And the 50mm has the advantage of f1.4.

Thanks
