What type of camera and lens can i buy for interior or architectural shots. Need this for my porfolio.?

Don is right that most professional interior and architectural photographs are done with 4x5 cameras due to the ability to control the film plane to give you parallel walls, etc. If you can only use a 35mm or digital SLR camera, you can get a "tilt-shift" lens. Canon and Nikon have made them in the past but I don't think they make them now. They can be found used on Ebay and at larger camera shops like B&H, KEH, Adorama and Calumet.

In general, wide angle lenses are used for interiors. For 35mm, you'll want 28mm, 24mm or possibly even 21mm for this. For digital SLR cameras, 20mm, 17mm or even down to 12mm might be useful. Thus, an "ultra wide zoom" like a 12-24mm on a digital SLR will cover this range.

Because there is so much perspective distortion with wide angle lenses, you can certainly use Photoshop or similar program to correct for this. It is probably because of Photoshop that camera companies no longer make tilt-shift lenses.

Hope this helps.

You have latitude with the interiors, 35mm will work fine but I recommend medium format for the quality. The very best architectural shots are done on large format cameras, 4x5 or 8x10. The large format lets you manipulate the film plane in relation to the lens, this will eliminate the "falling over" effect common to similar shots taken on the smaller formats. For both shots, but especially the interior ones, be sure to have a variety of lens types but to include for sure some wide angle capable hardware.

Sounds like you're a newbie in photography. Frankly the idea of a beginner using a medium format or large format camera is complicated and VERY expensive. I'd suggest you look for a digital SLR camera with a fixed wide angle lens or a wide zoom. Be aware that digital SLR factor up the focal length between 1.3 to 2 x depending on the manufacturer.

You should look for a lens that minimizes barrel distortion...since you want your verticals to be straight.

Perspective distortions used to be handled through expensive perspective control lenses, now you can correct perspective distortions easily and cheaply through photoshop.

The best is a large format camera. You have total control over the image, you can fix distortions caused with normal lenses. Although they are very bulky, heavy and take alot of time to set up for each shot. So i would recommend a meduim format camera with a shift lens. Or use a digital slr with a shift lens. They fix the distortion somwat.

I'm going to take this question in a very different direction and suggest you go for a simple point-and-shoot digital camera. As an architecture student, you should familiarize yourself with editing programs like Photoshop rather than waste too much time learning to be a professional photographer. Spend your time and energy on post-production!
