Other than lighten your wallet by at least $100, there’s little to gain from this package deal. Although, the 58mm universal lens hood MAY be of some benefit. It may also cause problems.
The 58mm wide angle and 2x telephoto lenses are really cheap products. I learned the hard way. I bought a ‘set’ like these two on
ebay about a year ago and on my first experiment with the telephoto, my autofocus 18-135mm lens could not focus (continuous hunting) so I went to manual focus. The results were worthless. Unscrewing the tele, the two parts of the tele itself unscrewed and the two elements and a couple of spacer rings went crashing to the floor. Both the tele and the unused macro immediately ended up in the trash. The 300 end of your 75-300 lens should be MORE than enough telephoto for you. And nothing says you can't zoom in on an ant from 5 feet away and get its picture.
As for the 3 piece filter set…the UV is worthless. Some may say it makes a good lens ‘protector’. But unless you deal with ocean spray or other watery, muddy, or other sloppy situations (doggie kisses?), it’s a decoration, and will likely degrade the image quality. The polarizer MAY be worthwhile. But as part of a low-price ‘set’ of filters, I’d be very leery. The polarizer will cut out reflected glare off surfaces like water, windows, etc. It can also be used to make the sky slightly bluer, if rotated just right. As a low-price filter as well, I’d be concerned with image degradation. And the FL filter, you have to be kidding me! Unless you are shooting film, and depending on which KIND of film, the FL filter is used to properly ‘color balance’ the florescent lighting and film. There’s all kinds of fluorescent lights ‘colors’ these days. Your camera has a ‘white balance’ (WB) setting, that can be set to ‘FL’ (fluorescent) or any other general setting such as daylight, shade, or even ‘automatic’. In many situations, using automatic will suffice. But it will bite you, especially indoors with incandescent lighting. Setting a Custom White Balance (CWB) requires a grey-card and setting it in the camera. If lighting changes, another shot of the grey card and re-setting it in the camera is required. It took several years for me to figure out I had to learn about the whole white balance thing. I still have a long ways to go before I could consider myself anywhere near ‘proficient’ at it.
The blue and orange filters? ??? Unless you want to experiment with unusual photograph coloring, they are probably worthless. If you have just about any photo editing software, you can change the colors to chartreuse or magenta or anything else with just a mouse click and drag or two.
One general note about filters. Myself and many others have found that in most cases, the lower priced, lesser-quality filters generally degrade the picture a noticeable amount. ANY glass placed in front of your lens will degrade the image. The quality of the glass and the quality and number of anti-reflection/diffraction coatings applied directly affect the results. One generally gets what one pays for. One lens rental dealer stacked a bunch of UV filters together and took a picture. The results were barely identifiable! Also, as expected, 10 ‘quality’ UV filters stacked together had significantly less degradation than 10 ‘cheapo’ UV filters stacked together.
Lastly, we come to the lens hood. I have strong reservations whether a ‘generic’ 58mm lens hood could work properly on both a wide-to-normal lens and a short-to-long telephoto lens. Frequently, hoods for wide to normal lenses are flower-petal shaped. This is due the rectangular shape of the image sensor and the wide ‘angle of view’ of the lens. The wider the angle of view, the shorter the lens hood, or else you’d see the lens hood in the corners of the image…or perhaps just a darkening of the picture corners, if it’s close. Telephoto lenses typically have longer hoods, as their angle of view is much narrower. Putting a short hood in front of a telephoto lens may not prevent much ‘light from odd side angles’ from entering the lens. Conversely, a longer hood on a wide angle lens would seriously limit the view to be very narrow. In short, a separate hood, designed for each particular lens, should be used. Check out your favorite web sites like
bhphotovideo.com (my personal favorite) or amazon.com, and search on the manufacturer of your lens and range like: Canon 18-55 or whatever. When looking at that particular lens, on the right side of the screen are optional equipment to go with that lens. You’ll find the correct hood listed there. Where you buy one is up to you.
Unfortunately, it is common for photographic dealers to sell ‘packages’ of filters, hoods, cleaning equipment, or even camera bags. Most of these items are at the lower end of quality and the higher end of markup (profit) for the dealer. Rather than some package deal, first determine what you need, then do your homework (web sites like this one or others), then buy decent equipment from a reputable dealer.
