Tamron 28-300 ld instruction manual

It is an internal focusing lens though, which is nice when shooting close-ups, although the 1. We're not complaining, but you might want to try this lens on your camera before committing to its purchase, just to make sure that it will focus properly for you at full tele.

Manual focus adjustment can be a little tricky with this lens, as there's very little rotational travel on the focus ring, from closest focus to infinity.

We found we could focus it manually OK, but it was definitely a little tweaky with middling subject distances. Macro operation happens as a natural consequence of the lens's design: There's no separate macro mode that you have to select for close focusing. Normal focus operation covers the full range from 1. Build Quality and Handling The Tamron mm handled better than we might have expected from a bargain super-zoom: Zoom operation in particularly was very smooth and fluid, and the lens as a whole felt quite solid and well-built.

The downside of the very smooth zoom operation though, was that the lens showed a slight tendency toward zoom creep. Any amount of jostling would let it overcome the restraint and zoom out beyond wherever we had left it. It wasn't as bad in this respect as some zooms we've used, but it's definitely still something to watch for. Besides its smooth zooming, we were also pleased by how compact this lens is: Set to its widest-angle position, it extends only about 85mm about 3.

Stowed at its wide angle setting, it presents a surprisingly demure profile, great for times when you don't want your camera rig to call a lot of attention to itself. The Competition As of this writing in early February, , we haven't tested any other lenses that cover this particular focal length range, but from what we've seen to date, it's awfully hard to find any sort of a zoom lens even a more purely telephoto zoom that performs well at mm for an affordable price.

These lenses likewise aren't stellar performers at telephoto focal lengths, but they do offer the one-lens solution for vacation travel that many casual users are looking for. Since this describes the shooting and usage patterns of a lot of casual photographers, the Tamron mm could indeed be a good choice for vacation use when you don't expect to need a lot of wide angle capability.

Sharpness Given the larger image circle that's required, we were surprised to see that the mm's corner sharpness in the trouble zone from mm didn't deteriorate much at all when we moved to the full-frame EOS-5D body.

On the other hand though, the corners got a lot softer from mm. Chromatic Aberration Looking at chromatic aberration, the increased demands of the larger image circle very closely balanced the relaxed tolerances of the 5D's larger pixels, leaving CA performance more or less the same on the 5D as on the 20D body.

Shading "Vignetting" Shading is probably where you'd expect to see the biggest difference going to a full-frame body, so it's probably no surprise that this was exactly what we saw with the 5D.

You can correct this in Photoshop reasonably easily, but who wants to spend that much time? Distortion Geometric distortion was also quite high on the 5D, interestingly shifting from strong barrel to strong pincushion over a very narrow range of focal lengths from mm Pincushion distortion decreased slowly from about 70mm onward.

Conclusion We've said it before, and we'll doubtless say it again in the future: If you've invested in a full-frame DSLR, it really doesn't make sense to subsequently try to economize by buying cheap lenses for it. If you only shoot snapshots with your own 5D or 1Ds Mark II, you might be happy with the Tamron mm on it which does in that case provide truly wide-angle shots at its short end. But if you're just shooting snapshots, do you really need a full-frame DSLR?

It's much lighter, a little smaller, a fraction of the price, doesn't draw nearly as much power and I rarely need IS anyway. Even so it's just better to avoid needing to use it. Trying to take handheld shots when it's so dark that I need to use IS, that's not a great way to get good photographs.

On this I have to chalk one up for "old-school" lenses. They force me to either use good technique or not bother to take the shot. Telescoping isn't a problem with the lock and having checked-out the Nikon and Canon options this lens actually looks the best, in terms of overall performance. It just pays to know how to get the most out of it, and to realize that at the longer focal-lengths you're going to need to shoot F13 or so to get a reasonably flat-sharp shot and a decent DOF.

I'd go through the blur-chart and note the F s of lowest blur at each FL. I wish that I could just program those into my camera. Beyond that, buy and enjoy. It is interesting to read the wide variety of reviews pro and con of this lens. It may not have the technical specs of a group of available lenses that together encompass this large zoom range, but for one lens it has no competition as far as I've found.

To put what you are about to read in context, I am an accredited photojournalist and have won several awards for my photography. I was on a tight budget and the camera store recommended it, so I took their advice. I have since upgraded my cameras several times, now shooting primarily with a Nikon D3, with a D as a second camera body.

I also have several Nikon lenses, for limited-use applications. The problem is a lack of a broad range, Nikon brand zoom lens for their full frame FX sensor Nikon cameras as opposed to DX lenses for the smaller chip. Even though I never use my D anymore, most of my shots taken with the D3 are taken in combination with my trusty Tamrom mm lens. It consistently takes good photos. I made a huge mistake a few months ago by buying Tamron's new VC version of this lens.

That lens is a disaster. After missing several easy shots at my daughter's graduation due to the lens not focusing instead, it hunted back and forth , I took the lens back to the store -- only to learn that other shooters had returned their Tamron VC mm lenses too. Another of my fellow journalists returned his for the same reason. This non-VC Tamron mm Nikon-mount lens is great if you want or need to travel light by bringing only your camera with a single, attached lens.

It has a great zoom range and auto-focuses well. Note that there are some Nikon models that this lens will not auto-focus with, so be sure to verify your application before ordering one. Granted this lens is not great in low light with older cameras, but the newer Nikons including the D3, D, D and others have terrific low light sensitivity so the lens' low light capabilities do not matter that much.

Simply set these camera bodies in their Auto-ISO mode, attach this Tamron lens and you'll be good to go for most situations. Using a relatively high shutter speed, my Nikon D3 and my aging Tamron lens, I was able to shoot sharp shots of a motorcycle stunt-jumping exhibition outside of the Palms hotel in Las Vegas at night, during the recent SEMA Show.

The motorcycles, as they jumped high in the air, were lit only by a couple of spotlights. The results were amazing. I have repeatedly asked Nikon reps for such a lens from Nikon for use with their new, full frame cameras D3 and D They tell me they cannot make one that would sell for a low enough price that people would be willing to pay. Go figure. Perhaps someday Nikon will listen and make such a lens available. I have an older non-DI version I bought as a travel lens because of the zoom range.

I've used it on a F3, F and a D Because mine is made for FX, much of the distortion is cut off on the Dwhich helps. The lens seems to have its best optical performance between 50mm and about mm at f8-f Forget about the extremes in range and f stops, it just gets soft and washed out.

I recently bought a Nikkor VR for the D80 which I think is a much better lens over the Tamron's usable range - for less money. I've taken some outstanding shots with this lens. I've also taken some not so good shots which could have been better had I had a sharper, faster lens. This circular diaphragm retains a nearly circular shape even at two stops down from its maximum aperture.

MTF Modulation Transfer Function curves describe to what extent the tested lens can faithfully reproduce contrast of the subject in images it captures. Lens performance differs depending upon directions.

Solid lines show performance in the sagittal radial direction while dotted lines indicate performance in the meridional circumferential direction. When sharp lenses capable of delivering uniform optical performance over the entire image field are tested, MTF charts show curves plotted in good balance. Performance characteristics of photographic lenses cannot be expressed with only MTF charts.

There are other factors that are expressed in different methods, such as taste of softness and degrees of compensation of various aberrations. But you can use MTF charts as a scale to measure lens performance. Catalogs Photo Gallery Spanish page. Tamron mm f3.
