Granted it is not fixed aperture. Looks like the max aperture may be f/8.

So I wanted to ask you gurus if you know of anything other than using my other eye that I also have vision problems with,Is there any type of adapter you can use to help in focusing since these older lense are all focused by hand rather than a program in the camera or lense.

Guess what I'm saying is I have Glaucoma and an astigmatism in my right eye and wear eyeglasses,but try to use my left eye (I'm right eye dominant) to achieve better focus.

For now I simply move my focus in and out by fractions to achieve what I hope will get me a highly defined picture ,download them all and take the best of the lot.

I have seen an eyepiece cover that will fit my cameras that say + or -,.5,.1.0,1.5 that would seem maybe to help a bit.Any ideas or info would be helpful as my intentions are to spend more time outdoors traveling my state this yr to places I can drive to relatively easy as I have recently had surgery and looks like more is on the way.So my benchrest shooting days are going away for a while and thought this will be an interesting hobby to get back into in the meantime while I heal hopefuly.

Walking and sitting for lengthy period of time are probably out but I did purchase an adapter to mount my camera to my car window and can probably make relatively short ventures in N.W.Ga.and my local areas to take pics and just in general photos of the many scenarios locally(waterfalls,dam's lakes,widlife areas,etc)

Thanks,Tommy

you might look for a nice used newer model with large 3in lcd screen and use the 'live view' for focusing. this will allow you to use both eyes (or either one) to aid in the fine focus.

I thought about that.I don't know if it would help what I see thru the screen tho.I have been looking at some programs that I could use a phone with attached to the camera,but that still seems to require a camera or lense that works utilizing a motor of sorts.These are not those types of lense so still looking around at things,maybe my optometrist knows something I can look into

I'm getting close but sometimes actions require a quicker shot to be taken,still shots or waterfall shots shouldn't be a problem as the cameras allow multiple shots in succession and I am using a remote to aid in keeping the shots off a tripod stabilized.

I'll attempt some moon shots soon hopefully if it would just appear in the future with the big zoomer as I call it,or maybe even a few planets as I have attached a 2x adapter to it.

Dunno,maybe just keep speramentin I may keep and eye out for a decent price on a possibly newer camere.The older 20D's had a good reputation and have a lot you can do with them so that was an easy decision

Thanks for the suggestion tho. Hope somebody here got that tripod,it was a great deal for the $10 it got sold for seems

Hah,I found I have an diopter adjustment on the camera (helps to read manual) that should take care of things

Thanks Tommy

I've been trying to work on my bird shots. Above is one by a friend I went to high school with. It is far from his best but one I readily found. Brian Smith takes nature shots and works hard at it. He is somewhere in VA and near a large military base. Apparently these guys have set up platforms, use camouflage outfits, screens, tents, including covering their cameras and tripods.

Brian uses a high end full frame Canon with a f4 600mm lens. He says that is what his friends use also. Nikon or Canon. These are $5K bodies and $12K lenses. The lense have a large diameter and are pretty long and heavy. Heavier than I'm going to carry. I am using the latest Oly mft with pro lenses including a 2x teleconverter and cannot duplicate their image quality. Oly makes a pro lens that is 300mm f4 ( same as 600mm f4 ff lens). It is a step above any I own at about $2,500. I've yet to come close to these 600mm f4, fframe efforts.

Regarding sharp focus, Oly and perhaps others have a feature called focus peaking that helps with manual focusing. Automatic focus is very, very fast but in some shots you might want to manually focus. When using this feature whatever is in sharp focus is highlighted with red, or yellow or whatever color you choose. This is pretty sensitive and seems to be very accurate. The object is magnified and you get sparkling lighting around exactly what is in focus. There is also eye priority...even left or right eye. It is very important to get the eyes in focus. One of the first things an observer looks at. Out of focus, dead eyes ruin the shot.

Having said all of that some award photos are more about capturing a interesting photo rather than technical perfection. However, most are by experienced photographers with top of the line equipment. Playing around with old equipment is ok in my opinion but won't likely compete with the latest stabilized systems when it comes to telephoto shots. Street shots and a lot of cameras are good for the job including cell phones from what I see.



This bird is 12' away, shot with 600mm f5.6 and is nowhere near as clear, sharp and bright as Brian's shot. It has also not benefited from any post processing. I don't know how to do that. I'm wondering if my mft sensor is going to be able to compete with ff sensors...regardless of lens quality, stabilization, etc. On the other hand....visiting the Oly site shows some folks are just better photographers than I am. Getting better shots, better lit, more character to the image, etc. and using my imagination are all things I am constantly working on. Photography is fun....but like a fine target rifle, I'm not sure I am going to be able to compete with the equipment I have. One day I am going to rent one of these expensive rigs and see if it is camera or me. I expect it is some of both.. 1917

I picked up this Nikon Nikkormat FTN in 1970, and took it all over the world until I retired it in 1987.


At that time my company started selling Canon Video equipment and offered us their photographic equipment for 50% off retail!
So I switched brands.

This camera has been in a leather camera bag along with 3 other lenses, filters, and other paraphernalia sitting in the attic above my garage for 32 years.
It gets somewhat cold in the winter, but over 100 during the summer.

My wife brought it down yesterday when she was retrieving Christmas stuff.
Shockingly it's in perfect condition except for some nicks on the Nikkormat name plate.
I have no idea how those happened, but it's in mint condition other than that.
Today I installed a batterie, and everything seems to work perfectly.

I'm still astonished by how great of condition it's in.
I take good care of my stuff, but come on man, that camera had a ton of use over those 17 years, and then was unused and got been baked for three decades.
So I'm kinda proud of myself for being such a good care taker. Maybe I should say a "lucky care taker" after leaving it to die in the attic.

It will now be displayed on a shelf in my Library.

Great result! As I age, I love AF! On most cameras in the viewfinder, there should also be a focus indicator...Nikons it is two triangles, with a central dot. When the dot is illuminated steadily, you are is in focus. Then there is that blasted, annoying beep that you can engage through the menus that lets you know if it is focusing.

Now we're a four Sigma lens family

Mrs. Cow:
100-400mm
Just bought - 17-70mm for close-ups

Me:
150-600mm
Just bought - 18-200mm for walking (street photos)

Both lenses are remarkable. I'm very pleased!
