The new lens dilemma [16-35L] took a nose dive and now I have to start over. Our county fair starts this week,and I really needed a wide angle lens. I stopped by a local photo shop and came across the lens I took this photo of our 2 girls with. What a deal,the oldest looks like me [she's a brute,I told her to stick her belly out!] and the youngest looks like mom-blonde,blue eyes,thin. We call them Slim & Sluggo.

Man,this lens is ancient! but it really don't do too bad. Enough to get me by in this pinch. This was shot in jpeg and cropped in photoshop-that's it.

The lens is an old 35-70mm Canon with the old arc drive focus. The old bugger still focuses pretty quick for not having usm-plenty fast for portraits. For $50 I can't gripe too much. 2702999810_9067a36de8_o.jpg

I may remove the photo after while,because whether we like it or not,I'm sure the ocassional pervert rolls thru.

MM, I know a candid pregnancy photographer who still uses the 35-70 because she knows it well and it does what she wants it to do.

Portrait lenses in structured settings don't need to open to f1.2 or focus lightning fast, and many, many portraits require a bit of softness to make them really sing for the customer (how many customers want their stretch marks and wrinkles, their kids' zits, or fleshy pockets emphasized by a razor sharp lens?)

And this looks plenty sharp to me, as do the portraits from the photographer I mentioned. You've got a good tool that works well for you. What else should there be? And when you want wider than 35mm, a new 17-40 f4L is sitting there for way less than even a used 16-35 f2.8L Mk1. And a used 17-40 will be quite a bit lower. You rarely would need the extra stop of aperture anyway unless you're doing low-light performance photography.

And if you want something really sharp, the Canon 50mm f1.8, the so-called "nifty fifty," is about $80 new. Plastic body, slow and loud focus, but golly does it have sharp glass! I know half a dozen pros who keep it in their camera bags at all times. And if it happens to be a little too sharp in wrinkly situations, a little gaussian blur in photoshop goes a long way. gringrin

I agree about zapping the pic. Creepy crawlies are everywhere, and DEET does not protect against that kind of vermin. An ounce of prevention is worth more than a .357 of cure.

I will strongly consider another 17-40,point very well made-and taken!

Now,candid pregnancy photography??..........nope,I'm not going there. Tried it once,and my Sony point and shoot hit the wall and shattered. Guess i should have told the wife I was being "tasteful" eek

MM, there's a market for everything, and photographs of pregnant couples, particularly B&W images in good taste, are becoming very popular.

So much to be done with lighting, angles, shades, lines and composition there, all complementing the most fertile and symbolic of human forms. I'm reminded of the Alfred Hitchcock signature that was a single line showing his distinctive (and pregnant-like) physical profile. gringrin

      Before you begin, make sure you have a good strong battery and make sure it's charged up. If you have a bad or weak battery, you may want to replace it because if it doesn't crank good and strong, you are likely to get a low, inaccurate reading. Make sure your engine is warmed up to operating temperature(if possible). About 10 minutes of riding should do.

      First, take out the spark plug and thread in the adapter for the compression tester. Make sure you have the correct size adapter for your particular ATV. Slide your kill switch to the "off" position. Some ATVs won't crank over with the kill switch in the "off" position, so if yours is like this, then you will need to either unhook your ignition coil or ground the end of the spark plug wire to a good ground. You can use a jumper wire with alligator clips on each end to ground it. Next, make sure the throttle is in the wide open position. You can either hold the throttle lever with your thumb or you may be able to tape it or use a zip tie to fasten it to your handlebars to hold it in the wide open position. If you don't have the throttle in the wide open position, you will probably get too low of a reading. Also, if you are testing a newly rebuilt engine, the engine needs to have been run for, at least, 30 or 40 minutes or you will probably get too low of a reading.

      NOTE: Before you begin with the actual test, make sure the threaded adapter is screwed in good and isn't leaking any air out around it.


      With the throttle in the wide open position, push the start button and crank the engine over until the hand on the gauge stops moving. Each time the engine turns over the hand should raise a little more until it reaches the maximum compression of the engine. When it stops, that is your compression reading. This usually takes no more than 10 seconds. Try to avoid cranking an engine for more than 10 seconds at a time as this is hard on the starter and the battery. Now, push the relief valve on your compression gauge and that will reset the hand back to zero. It's a good ideal to repeat the test a couple or three times to make sure you get an accurate reading. On kick start models, it will be the same procedure, but obviously you will be kicking it over instead of using a start button. Worn piston rings and cylinder walls will increase the number of strokes it takes to reach the maximum reading. If you're kicking, it could possibly take as many as 10-20 kicks to get the highest reading.


      You will need to check your repair manual for your particular model for the correct compression specifications. See note below. Usually, an engine will run OK if it has at least 100 PSI of compression. Most engines will have somewhere between 100-250 and some as high as 300 PSI, depending on the engine. Sometimes they will run with under 100 PSI, but usually not very well. If you get a low reading, you can do a "wet test" to try to help determine the problem.

      If your reading is too high, then you probably have carbon built up on your piston and combustion chamber.

      NOTE: You may get a low reading on some engines because some engines have a decompressor assembly built into the camshaft. Check the service manual for your quad to see whether or not your quad has a decompressor assembly built into the cam.

      WET TEST

      If you got a low reading, pour about 1-2 teaspoons of clean motor oil down into the cylinder through the spark plug hole and do the compression test again. If your reading increases, then your rings or cylinder walls are probably worn. If your reading doesn't increase, then it's probably your valves. You could have a bent valve, you may have leaky valve seats, or your valve clearance may not be adjusted properly. Also, low compression can be caused by a blown head gasket.


      *Worn piston rings or worn or damaged cylinder walls
      *Leaking valves
      *Valve clearance not properly set
      *Blown head gasket

      CAUSE OF HIGH COMPRESSION (stock engines)

      *Carbon buildup in combustion chamber and on piston

      NOTE: Compression testing is a good way to keep track or "gauge" the wear in your engine. When you first get your ATV or when you rebuild the engine in your ATV, you can do a compression test and then later on, you can do them periodically. This will help you determine the wear in your engine each time you do a compression test and will guide you in knowing when your engine needs rebuilding.

      This is about all I can think of. I hope I didn't leave anything out and I hope this helps everyone with their compression tests.
    • As dumb as this sounds how is this done?
    • Try a compression check. And make sure the choke is opening all the way.
    • They are not the best out their but for the price and your average person not too bad I guess, Its going to send lead to where its pointed. This is probably what is going to happen he is going to buy a package shoot it for awhile then start upgrading everything to how he wants it and it is going to end up costing way more than if he just built one himself how he wants it.  
    • Hello, well I convinced my brother in-law to pick up my buddies old 1980 185 although pretty sure he said it was bored out to a 200? Here is the deal it's been sitting for a solid 8 years. I know it ran fine before. Not the delema-----   It starts right up (he bought a new carb odd amazon) although it sounds like a jet with high rpms. Looked at the throttle cable that's fine. Floats are fine. So he plugged this hole in the air filter and got it to idle down although when he hit the gas wouldn't get any power. Read a few things online and they tell you to just bypass the filter box and all that so back to amazon we went to get one of those filters that mount right up to the carb and it's still the same issue..   I just haven't seen anything like this? Do you guys have any thoughts or tricks that we/he could try?! Thanks in advance
    • Hi Everyone,  I'm looking into buying my first true fish finder and I'm a little perplex with the mapping card situation.  I'm looking at Humminbird Helix 5's and 7's.  I'm drawn to the autochart feature.  From my understanding, you can record 8 hours of charting onto the internal storage, but, is there any native mapping included on the unit or do I absolutely have to get some sort of mapping chip, zerolines or lake master, or navionics?  Can I store data on a blank SD card?  I've been researching this a lot and haven't found any conclusive answers. Thanks everyone!
