For the last year I've been using my Canon EF lenses on an A7rii with the Sigma MC-11. With good lighting and contrast the AF is decent but slow, and in low lighting it's quite poor.  Is the AF ...

I have a 70-200mm f4 IS lens that is in need of repair. I have the focus slipping issue which started a few years ago when I tilted the lens upward. It's now slipping when the lens is parallel to ...

I have about 8 Minolta lenses. I recently did a test on my A7rii between the Rokkor-x 50mm 1.4 MC & MD lenses.  Bokeh is very much the same on these, but there is a slight sharpness advantage that ...

Has anyone personally tried the Tokina 35mm 2.8 macro lens on a Sony A7 camera?  Just wondering how well it works (vignetting wise) at various distances and how satisfied you are with the lens?

Over the last year or two, I've experimented using some of my Canon lenses on my A7Rii using the Sigma MC-11 adapter.  I've had decent success with AF trying different combinations of settings, ...

Lots of praise here for the bokeh and general performance of Sigma's 40mm. Just wondering... when folks are comparing the 40mm with the 35mm, is it the older 35mm 1.4 or the newer 35mm 1.2 you are ...

You ask about the specs on my filter. I don't have one as yet. I'm looking for a round solid 52mm ND filter to use on various (mostly) manual lenses. They will be used on Canon 6D & SL1, Sony ...

BBuilder... I use Sony, Canon & have one Fuji camera. For the Sony & Canon, I should be ok at f1.2 with a 3 stop (if my math is correct).  There may be an issue with Fuji as they only go as low as ...

I have a general question regarding ND filters.  For shooting in bright sunlight on a camera who has fastest shutter speed of 1/4000.  How many stops in a ND filter would be appropriate for ...

Although I haven't seen that many samples of the 40mm, I did read a comment that the 40mm 1.4 and the new 35mm 1.2 have a similar great look regarding the bokeh. It's also a very usable focal ...

Some outstanding responses so far!  Great detailed explanations on the rendering of each lens and same amazing photos as well.  The amazing photos from the 20mm by Ben are surprising and ...

Sigma's art lenses have had a great reputation for sharpness, but the reviews seem to be varied when it comes to bokeh. (I'm referring to both out of focus lights and general smoothness of ...

The person who made the statement "creating something that doesn't exist, which is what PP is" has no clue as to what post processing is all about.  I worked once with a woman who thought the only ...

An update... I received the new 8gb cf card and the 30D still shows the error, so unfortunately, this old camera has had it. I have plenty of other cameras, so I'm not left without.  Thanks to ...

It probably would. Raw shooting would no longer make sense and I would be stuck with whatever came out of the camera. Post processing is not about taking a nice perfect picture that comes out of a ...

Thanks for the replies. Actually, I only paid $250 for the camera (used), but your point is a good one, $125 is too much for a thumb grip.  I did go on the website and do understand about the ...

I am considering purchasing the Lensmate thumb grip for a Fuji X-T100.  I use manual lenses quite often and I need access to press down the wheel which gives magnification to focus. I don't want ...

Thanks Kevin. I tried different lenses & cleaning the contacts. The new CF card should arrive at any time and I'll try that. Next attempt will be that smaller battery.

Well thanks everyone. I think I'll be fine if I stick with 8gb or less.  Hopefully my issue with the 30D is CF card related. We'll see. Thanks again.

Actually, I have plenty of bodies, so its not that I'm in need of one. I just enjoyed using the 30D occasionally. If I tossed it, I wouldn't replace it. There is a possibility that the issue is ...
