Next lens for K-7 user

Hi Guys,

I have had my K-7 for about 3 years now and feel I need a bit more diversity with my lens choices. My favourite and most used lens is my Pentax SMC 50mm 1.4. I also have the DA 18-55 stock lens that came with the camera, however I don't like the limited aperture at length. I also have a Sigma DG 28-300 3.5-6.3, which was an early acquisition that I now never use, frankly that purchase was a mistake.

I want a two lens kit, which will consist of my 50mm and one other lens. I take quite a lot of photography of food, however want some wider angle shots for traveling and feel that the DA*16-50mm f2.8 would be a good fit.

Let's say money is no factor, what are your recommendations for a fairly un-specialized photographer who wants a bit more range. Would a wider prime lens be a good match for my 50?

I have a 43mm F1.9, 77mm F1.8 and 200mm F2.8, all of which I use very regularly. I mostly shoot wildlife so the 200mm is usually on my camera. I also do a lot of people photography, using all three lenses.

Sitting unloved in a cupboard are a 16-45mm F4, which gets very occasional use for flowers as it does macro, and a 55-300mm f4-5.6, which just never gets used any more.

I guess my favourite subjects take me in the opposite direction to yours - ie: tele instead of wide.

It does sound like a wide prime - say around 30mm - might really suit you. However, I can see that a quality zoom at around F2.8 would be very versatile.

I think the DA* 16 - 50 would be an outstanding lens for your needs.

Why not read the attached review, which will give you some insight into the performance of the various 2.8 16-50 available.This would seem a good versatile lens options for food photography.

Some years ago I picked the Tamron 17-50/2.8 for this general purpose use. It is a great versatile lens, but some time after that I decided that I can live without zoom capability, so now I stick with a few fast primes for vacations.

BTW, PF has reviewed these fast zooms here (boy, was it hard to find this link).

Thanks for the advice guys. Second question, if I were to go a prime lens of shorter focal length than my 50mm, what would be some good options?

Both 28mm and 35mm seem popular these days.
I managed to cover off both with the Sigma 20mm-40mm with I luuuurve. It practically lives on my K5 these days.

(PS; if you think of selling the 28-300; lemme know )

I really like my Sigma 30 mm 1.4, which of course is equivalent to 45mm on full-frame, a great prime lens for lots of low-light, inside work, even including portraits. For more money,I also like my Pentax 43mm ltd. I second the recommendation of the Tamron 17-50mm constant f 2.8, excellent for inside parties and gatherings for ease of use in ambient light, and also a great "walking around" lens for its focal length coverage. As a walking around lens, it is wide enough to do architecture and landscape, yet narrow enough for portraiture. There are reviews of all these lens on this site, of course.

If price is no object go for the FA 31mm ltd. It is a stellar lens and still in high demand even after 12 years (it came out in 2001) It is an auto focus lens. And a true jem.
