Editorial Review

The Canon LA-DC58 conversion lens adapter lets you use specially made Canon conversion lenses and 58mm filters. To use the converter, remove the ring around the lens and screw the adapter into place. This adapter is necessary when using the WC-DC58 wide-angle converter, the TC-DC58 teleconverter, and theclose-up lens 250D with the PowerShot G1 camera. ... Read more

This dont work with G3
I bought this accesory thinkingthat itwas compatible with the Canon powershot G3 (because it is in the list of accesories for this camera) but it doesnt work with the G3. Buyers beware. If you have a G3 you should buy a LA-DC58B instead.

My [two cents worth]
I have this adapter just in the need that I want to use the special effect filters..it serves this purpose very well, however, I've also noticed some drawbacks that annoy me quite often.

a) it blocks the build-in flash if you don't zoom in.
b) it blocks the low-light focus-assistant beam!! and for my G2, although it is a Canon Type-A camera, the red-light focus-assitant beam of the external flash Speedlite 420EX won't work.That said, you are taking risks on using autofocus, and if you are using those converters, say bye bye to autofocus.
c) my silver G2 looks bad with this BLACK adaptor...

Good if you have 58mm filters and Canon SLR Camera
This lens adapter has some advantages: 1- Wide opening (58mm) so reduce vignetting 2- Same filter size for Canon SLR like ELAN 7E, thus same filter set can be used for both Digital and film. 3- You can always keep it on the camera with an UV adapter, protecting your lens, don't forget the cap. Disadvantages: 1- Blocks viewfinder, you have to use LCD, which I always do because viewfinder never shows %100 coverage of real shot. 2- Blocks a slight portion of low light sensor, but I did some tests, it does not have much blockage and low light sensor works OK in my camera with this converter attached. 3- Blocks microphone, I did not test the effect of converter on microphone. Some notes: If you buy this converter, don't buy a non-coated filter because camera has an excellent coated lens, and you don't want to reduce your image quality with a [price] lens. Go for a [price] B+W or at least double coated hoya filter. ... Read more

Editorial Review

The field reference of choice for serious birders since its inception, the third edition has been updated to reflect new bird ranges in North America as well as the always controversial reclassifications of species and subspecies. The expanded text includes even more notes on identification, behavior, habitat, and song, while the illustrations--now revised and sharpened--depict individual species in varying plumage, often with habitat cues in the background. Like the first two editions, the guide combines accurate illustrations with useful maps and text in a portable format. Beginners and experts alike will flock to this handy field guide. ... Read more

Still a fine work
My natural history interests are mainly in botany and mycology, but I also have an interest in birding, and I own dozens of bird identification books, and this is one of my favorites. Although there may be better books for the field or for home reference now, such as the newer Sibley, Kaufmann, or Smithsonian books, this is still a good work for general identification purposes, and it's served me well for that. Since this one was written there has even been a large, Reader's Digest volume about 10 years ago that was actually pretty well done, I thought, so everybody seems to be getting into the act.

As another reviewer here perceptively pointed out, the paintings in this book are more modeled and 3-dimensional looking, compared to the classic Peterson book, which look flatter and less solid. Also, the colors are more muted, and therefore more realistic to me. Both the Peterson and NG books have good field notes and tips on behavior which are useful. The 3-volume Smithsonian guides have great pictures, of course, but they're better for home use since carrying three books in the field usually isn't practical.

There are other specific differences between this and the Peterson book, but others have already pointed these out here, so I'll just conclude by saying if I had to have just one guide, this would definitely be in my top 3 for the honor.

No longer required
5 years ago this field guide was required for all serious birders but with the new field guides this one isn't need any longer. It's a bit too big to easily carry around the field and Sibley's is a better guide for the home. Kaufman's Birds of NA is a better book to carry around.

If you like to have bird guides this is one of the best but it's no longer the best.

A bird book for the car......
For years, I've used the Peterson field guides to identify birds.Most of my bird watching has taken place in the Eastern U.S. mountains and north and south of the coastal area where I live, as well as WI (summer) and LA (winter). The Petersen guide book for the Eastern region meets most of my needs, but I also own several other books (Smithsonian and Audubon). I became interested in the National Geographic book BIRDS OF NORTH AMERICA because I admire the NG magazine.

The NG is a heavier book than the Eastern Peterson, perhaps because it shows birds from both the Eastern and Western areas of the country, but the Peterson maps show the full range of "Eastern" birds--even if a range extends to the West. Both books show ranges that extend into Canada. The NG book is nifty because the little maps that appear in the back of the Petersen books are on the same page as the bird illustrations.

The birds illustrated in both books are clustered by category. For example, Petersen shows male and female Downey, Hairy, Northern Three-toed, and Black-backed woodpeckers together, as does the NG. The Petersen guide has little arrows that point to distinguishing marks, but NG does not. I find these indicator arrows very helpful when I am trying to tell two closely marked birds apart. The NG does show a tiny row of variants across the bottom of the page (For example, the woodpecker page = fasciatus, dosalis, orius, etc.)

The bird colors are less differentiated in the Peterson than the NG illustrations. For example, stripes on the Peterson Three-toed woodpecker's belly are less articulated than those shown on the NG bird. I don't think this matters as one seldom gets close enough to see the mottling. The Peterson birds are hand drawn and relatively flat, while the NG birds are more rounded, i.e. modeled. The Petersen birds look like the Audubon paintings. The NG illustrations remind me of digital photos of taxidermist stuffed birds (probably why the colors are so differentiated).

Both books provide measurements and Latin names. The Peterson book provides text that describes birds that might prove confusing with your bird of interest. The NG book provides text that describes the attributes of regional variants. This latter feature won't help you in the field since you almost never see regional variants in the same location.

If you are a serious bird watcher you will probably want both books and the Audubon and Smithsonian books as well. If you can only afford one book, I recommend the Peterson book. I have used my Peterson book for so long it just falls open when I hold it in one hand, so I am probably prejudiced. ... Read more

Good Bird Note Book
As a black and white companion to the National Geographic bird book it is great. This note book gives you room to write and draw on the species of birds. One can use this book as a "life list" and record your sightings, locations, etc., into this. It is amazing to sit down with this book years later and review your past findings. This book goes along exactly with the bird book and I usually keep both with me at all times for recording and identifying.........

An excellent gift for any North American birdwatcher
Now available in an updated and expanded second edition, Mel Baughman's The Birder's Journal is a consumable volume for the personal use and notations of North American birdwatchers. Though it has very basic information on over 60 North American bird families, the bulk of this thick compendium consists of accurate, detailed black-and-white sketches of over 850 bird species, next to allotted writing space where the birdwatcher can make his or her own notes about when, how, and where that species of bird was successfully observed. The Birder's Journal is a perfect aid to keep track of the all the different feathered friends one has seen, and an excellent gift selection for any North American birdwatcher.

NGS Field Guide - A Disappointment
This journal is a gray-scale (black and white) version of the popular and very useful NGS field guide.Nothing new is added except blank lines for brief field notes - which replace the descriptive text adjacent to the colored illustration as found in the field guide. Most - but not all - of the birds currently listed by the AOU are represented.

However, as a "fully illustrated" journal in which to record one's first sightings, it functions only marginally better than the check-boxes in a field guide index - again, by providing something more than a margin in which to record notes.

...

Also compare the Audubon Society's entry into the field.This pretty journal, in the style of a diary, would serve quite appropriately as a gift for a young woman or teenage girl just beginning the birding experience.Very few of the 1000+ birds in the AOU Checklist for our region are represented, however.

Each of these journals serves the purpose of providing space for keeping track of the birds one has identified in the field, but each will appeal to a select audience.The NGS Birder's Journal doesn't go beyond the basic requirement of providing space.

Life-List Illustrated and the Audubon Journal bring a desirable esthetic element to the process. ... Read more
