Default Which one of these please?

hi,i want to buy a new lens for my a550,i like shooting everything,but mostly landscape and portraits,so i am looking for something that will serve me in both ends,prices are a little high but i am willing to wait...so which one of the bottom would be a better choice?thank you all for your helps!

Tamron 28-75mm f/2.8 XR Di LD (probably the most expensive choice)

Tamron SP AF 24-135 F3.5-5.6 AD Aspherical IF Macro (if i can actually find one)

Sigma 18-125mm F3.8-5.6 DC HSM (quite tempted with the range)

Minolta AF 24-105 F3.5-4.5 D(if i can find a good copy for a good price)

Minolta AF 24-85 F3.5-4.5 RS (probably the cheapest option)

Minolta AF 28-105 F3.5-4.5 RS (it isnt wide enough but range looks good)

Minolta AF 28-135 F4-4.5 (hard to find a good one)


Image queslity is very important to me,and also being able to use it for both purposes would be great,i am very tempted with sigma and tamron 28-75(f2.8 sound great) but again money is important....if you have any other suggestions please tell me,thank you all again!

Have you researched these on Dyxum?

On an A550, 28mm, or even 24mm, is not very wide for landscape.

The Sigma 18-125 might do the landscapes well, but the maximum aperture is small for portraiture.

Any one lens will be a compromise for what you've got in mind.

Is there something about your 18-55 kit lens that you find unsuitable for shooting landscapes?

Is there something about your 50/1.8 lens that you find unsuitable for shooting portriats?

If you want to utilize all the features of your new camera, you will want a lens with 8 electrical contacts on the mount. Older Minolta (use only Maxxum lenses) have only five - they are optically excellent, but do not support all the functions of newer cameras. If you want more modern through the lens flash automation with external flashes make sure the lenses are maxxum D or DT, and that the flash supports that function. Any digital AF Pentax mount lens from any major manufacturer will have the necessary contacts.

The extra 3 contacts are just for the Advanced Distance Integration, which was first introduced in the Minolta Maxxum 7. It provides focus distance information to the flash. If you're not using flash, then these three contacts provide no essential, or even useful, information.

The "DT" designation identifies Minolta and Sony lenses that project a smaller image circle than conventional lenses. This smaller image circle is appropriate for the smaller APS-C image sensors in most dSLRs, but doesn't cover the area used for 35mm film or 'Full Frame' image sensors in some dSLRs.

On an A550, the "DT" designation is inconsequential, and if you're not using flash, the "D" designation is also inconsequential.
