If you routinely do cropping it is. In my case I finally have 24 MP APS-C cameras in both Pentax and Canon (K-3 II and 80D) this year. K-3 III will have to wait. I plan on doing some telephoto ...

I just bought one of their 128GB U3 micro-SDXC cards and it worked fine in the used Canon 80D I just picked up. Have not tried one in my K1 or K3II yet. I will buy another one and try it in a ...

If I remember correctly Pentax's native exposure is designed so that data from the low light parts can still be pulled out without blowing the highlights out.  Canon's native exposure is very ...

Too slow. If the AF is to start you will never get a good shot until the 3rd shot or so if the AF turns on because it can only check the AF accuracy between the shots when in AF-C. The reason why ...

It says PASM and records EXIF data so I would say PKA or even KAF3 w/no AF. I actually have the Irix 11/4 Blackstone I just don't remember as I have not been able to shoot much lately. What ...

Wide lens? I have the Irix 11mm F4 Blackstone in PK. Kent Gittings

True, not enough sensation of speed in the photo.  Wheels, like an aircraft propeller, have to blur completely if you can do it. Kent Gittings

Its an Oreca LMP.  Nice panning. I shot the 2017 Rolex 24 at Daytona. It was my last race as a photographer. I was actually down there invited by one of the Porsche teams in the Weathertech GT4 ...

Can't really use a TC on a lens that is slower than F5.6, at least to get AF to work. But this is a manual lens and I would stillnot bother myself. In my film days I had the only AF lens that ...

I think I still have both a 60-300 and a 70-210/3.5-4.2 ADII lenses but no Pentax adapters for them. May have a couple of original ADaptall ones like the 38-100/3.5. Also had a pair of the 90mm ...

I once used the Pentax AFA 1.7x TC with both the 60B 300/2.8 and my later 360B model also. My 400/4 belonged to the person who ran the Adaptall.com website. It was fully restored by him and he ...

When I had a collection of all the big Tamron ADaptall II lenses I pretty much used the 400/4, 300/2.8, and the 200-500/5.6 only on monopods. I used them only with the Tamron KA adapters. I did a ...

Pretty sure its a replica. The gas cap is in the wrong place as it should be on top of the right rear fender. Kent Gittings

Oh I really like those, Dean. Excellent panning and AF point control. Pentax 300/4 I presume. Kent Gittings

I agree. I recently acquired a kit with a K-3II and a Sigma 180/3.5 EX DG HSM Macro. Another lens thrown in was a  Pentax DA 16-45/4. I love fixed aperture zooms as they tend to be best of brand.  ...

If the camera you are using is a combined F8 it needs to be a pro one to get the most out of it because only those cameras are guaranteed to focus fast and accurate at F8 or you have to use it in ...

Correct. Plus you had to find some object you could carry with you that corresponded to the greyscale level of Zone VI for metering. In my brother's case it was a gray sock believe it or not. He ...

Not me but my brother is a pro who works in B&W a lot. You have to be a master of natural lighting and fully understand the Zone system to get the correct level of contrast. I never had the chance ...

Ditto buy the factory refurbished one. Grey market means it has to be shipped overseas to get fixed. You don't want that if you live in the US. You might check to see if the retailer has their own ...

Are you sure you don't have the 60D? the D60 was their second DSLR and it only had 4 MP. Kent Gittings
